AG真人游戏 Steel has detailed a comparison of steel vs stainless steel, including properties, applications, costs and many other important factors.Stainless steel and steel are alloy steels with unique strengths and applications. Understanding the difference between these two types of steel is fundamental to choosing the right material for the project. The difference between steel and stainless steel lies in their composition and propertiesGeneral introduction to steel vs stainless steelsSteel is an alloy of iron and carbon, combined with a number of other elements such as nickel, molybdenum, manganese, titanium,... to determine the mechanical properties. Steel is a metallic material so it has metallic luster, strong electrical and thermal conductivity. At temperatures of 500-600 degrees Celsius, steel becomes ductile and its strength decreases. At -45 degrees Celsius, steel is brittle and prone to cracking.Stainless steel is also a type of alloy steel commonly used in life. The difference is that they have a minimum chromium content of 10.5 wt% and a maximum of 1.2 wt% carbon. Thanks to this special composition, stainless steel has outstanding resistance to corrosion and rust.Stainless steel is generally stronger than conventional steel in various applications due to its unique composition and propertiesLearn about the difference in properties of steel and stainless steelSteel vs. stainless can be based on the features in property of steel below:Corrosion resistanceCompared to conventional steel, stainless steel has superior corrosion resistance thanks to its 10.5% chromium content. When exposed to outside air, chromium creates a layer of chromium oxide (III) that cannot be seen with the naked eye, so the surface of stainless steel is always shiny. Molybdenum in stainless steel is also highly resistant to corrosion, even in acidic environments.StrengthIs stainless steel stronger than steel? Steel is a material with high tensile strength ranging from 400 - 1882 MPa, good bearing capacity. Meanwhile, the tensile strength of stainless steel is about 518-827 MPa, with standard strength, heat resistance and hardness.Therefore, while stainless steel can be strong in some applications, high-carbon steel can have a higher tensile strength than some types of stainless steel.DuctilityThe carbon content in steel is no more than 2.14% by weight. The more carbon in steel, the higher the hardness and durability of the steel. While stainless steel only has a maximum of 1.2 wt% carbon, it is more flexible and easier to shape than conventional steel.AppearanceStainless steel has a high chromium content, so it has a smooth, shiny appearance. For applications requiring high aesthetics, stainless steel is a more ideal material than conventional steel.MagnetismUsually people still think that stainless steel is a non-magnetic or non-magnetic material. In fact, the structure of the metal will determine whether stainless steel is magnetic or not. Of the 4 groups of stainless steel, only the Austenitic group is non-magnetic and the remaining 3 groups are all magnetic. Therefore, if the stainless steel you are using belongs to the magnetic Martensitic, Ferritic or Duplex groups, then when tested with a magnet, the steel will still be attracted like ferromagnetic materials.What is the difference between steel and stainless steel?Steel vs stainless steel: which is the better cost?The input materials of steel are mainly iron, carbon and some other chemical elements, while the chromium content in stainless steel is very high, further increasing the cost. The steel production process is also simpler than stainless steel, optimizing energy and labor costs. In addition, processing and manufacturing stainless steel requires high expertise and complexity, leading to the price of finished stainless steel being more expensive than steel products.How is the difference between the applications of steel vs stainless steelStainless steel stands out with its resistance to corrosion, rust and extremely high aesthetics, so it can work in many harsh environments such as the petrochemical field, aerospace, marine,... Stainless steel does not contain chemicals harmful to users' health, so it is an ideal material for use in the medical and food industries.Meanwhile, steel has high mechanical properties, has many different types and uses, so it is applied in a variety of industries such as construction, mechanics, shipbuilding,...Conclusion on the most distinctive differencesFactorsSteelStainless steelKey raw materialsMade of iron, carbon and some other metalsMade of iron, chromium and some other metals.StrengthHigh tensile strength, susceptible to corrosion and rust in natural conditions, low heat resistanceLower tensile strength, easy to shape, extremely good resistance to corrosion and rust.ApplicationUsed in civil construction, equipment, automobile components,...Used in the fields of medicine, food, furniture, chemicals,...AG真人游戏 Steel - Bringing the best Vietnamese steel import experienceOnce one of the smallest economies in Southeast Asia, Vietnam has now become leading economic markets in the world, especially in the field of metal import and export.

With new roles such as helping to shape human life, participating in all current fields, and contributing to revolutionizing industries.However, not everyone knows about the development history of this industrial revolution. AG真人游戏 Steel sends you information about this revolution in the article below!The steel industrial revolution is a step in the development of human civilizationWhen did the steel industrial revolution begin?When was steel first made? Steel was first manufactured in ancient times, but in this period, the steel industry was located in places with raw materials, electricity, and running water to facilitate the production process. However, it was not until the 1850s that the history of the steel industry began to develop. In 1857, thanks to the development of the Bessemer converter by Henry Bessemer, steel was mass produced. Since then, steel has become a staple of the world's industrial economy and soon replaced iron in the construction industry.The steel industrial revolution marked a leap forward in the history of human civilization. The flexibility and sturdiness of steel today is not only used in construction but is also commonly used in many other industries.What was steel used for in the industrial revolutionThe steel industry has opened new doors for human civilization. The steel history timeline has marked the development of the world economy. With its advantages and versatility, steel is used in many different industries. Below are some applications of steel in the industrial revolution.Steel is widely used in construction architecture. After gradually changing iron in the construction process, steel seems to open a new era of skyscrapers and modern architectural works. Iconic skyscrapers represent famous architectural works today, such as the Eiffel Tower, Burj Khalifa in Dubai, Shanghai Tower in China, and Lotte World Tower in Korea. It's all a testament to the transformative power of steel in building architecture.Eiffel Tower - A famous structure made of steelSteel is used in transportation The steel industrial revolution plays a huge role in the development of transportation infrastructure. The advent of the railway industry saw a transformation with the widespread adoption of steel rails, allowing trains to travel at higher speeds and carry heavier loads. Besides, steel also contributed to the construction of iconic steel bridges, including the Brooklyn Bridge and the Golden Gate Bridge. These are two bridges that demonstrate the outstanding strength of steel in building modern transportation routes. In addition, steel in the industrial revolution was also used to build ships, cars, and aircraft.Steel and industrialization The steel industrial revolution ushered in a new civilization in human history, and steel played a central role in driving this enormous change. Steel is associated with the industrialization process as it gradually replaces iron to become the main component in the construction process. Thanks to Henry Bessemer's Bessemer converter, the history of the steel industry reached new heights by revolutionizing production processes and increasing productivity on an unprecedented scale. Steel has had a great impact on the industrialization process, contributing to promoting economic growth.Steel in daily life Steel is widely used in daily life; household appliances, furniture, tables, chairs,... all have the appearance of steel; they help our lives. We become more modern and aesthetic. Steel's ubiquity in everyday life speaks to its invaluable role in shaping modern society.Steel is used to make household appliancesChallenges and innovations in the steel industrySteel production is one of the core industries of the global economy. However, like any other industry, the steel industry is facing challenges and innovations in steel production.Fluctuating market conditions In fact, the steel industry has passed through the development stage and is in a period of saturation when facing volatile market conditions. In the context of inflation and the global economic recession, steel prices continuously decrease, which reflects the difficult reality of the production and business of steel industry enterprises.Climate changeClimate change is one of the biggest challenges today. The steel industrial revolution led to mass production of steel, which in turn uses a lot of energy and produces large amounts of emissions. Reducing emissions and saving energy is one of the important requirements for this industry. This also requires steel manufacturing businesses to find ways to reduce emissions and increase sustainability in the production process.New technology When technology continuously changes and develops, it directly affects the steel production industry. This forces steel manufacturing businesses to keep up with new technology to improve product quality. However, along with new technology comes the cost of investing in production lines, which is also a big barrier for steel manufacturers.Future direction of the steel industryThe steel industrial revolution has brought the steel industry to develop dramatically, becoming a key sector of the world economy. Looking at the current situation of the iron ore market and steel industry, one of the future directions that the steel industry wants to aim for is the development of the green steel industry. When governments around the world introduce many new regulations as well as carbon taxes to improve the environment, green steel production is a goal that is both vital to the steel industry and contributes to limiting warming.Currently, many of the world's leading steel manufacturers have started producing green steel or have set goals in the next few decades to no longer use fossil fuels. Vietnam's steel industry also aims to be carbon-neutral by 2050. Green steel is not only a trend but also a necessary step to protect the environment and create a sustainable steel industry in the future.Green steel production is gradually becoming a trend in the futureAG真人游戏 Steel - The future of Vietnam's steel industryIn recent years, Vietnam has grown to become one of the world's major crude steel production powers.

The importance and significance of steel in today's world cannot be denied. Steel is considered the spine of a modern, civilized, and progressive society. But when was steel invented? How is the development process?In the article below, AG真人游戏 Steel will help you learn about the history of the formation and development of the steel industry.When was steel invented? Let's find out belowWhen was steel invented?It is difficult to have an exact answer to the question 鈥淲hen was steel invented?鈥� Many people think steel appeared at the beginning of the industrial revolution, but it appeared a long time ago. After the Iron Age, from the 13th century BC, steel was invented by heating iron in a hot fire, at which point the iron would become harder and stronger. Since then, people have found traces of steel in many different cultures and territories around the world, and usually only a few shapes of steel are made for use in everyday life.However, the early invention of steel had a wide range of carbon in the metal, from less than 0.1% (low carbon steel) to 1% (high carbon steel), which could lead to steel with a higher carbon content being very brittle. This brittleness can be reduced by tempering the steel, which is a form of heat treatment that was used in Egypt as early as 900 BC.Later, in the mid-1850s, Henry Bessemer, the British inventor first created a method to produce steel in large quantities. Since then, steel has been produced based on the Bessemer process. The operating principle of this process is to heat iron ore and other chemicals, then blow oxygen into the blast furnace to separate impurities from the metal mixture. This method is similar to the steel production method we are using today.Bessemer steel making processUntil now, the creation of steel was essential to human life. Steel is always ahead of the game and is commonly used in construction and many different industries. There are a number of reasons for this, from the variety of shapes it can be formed into to its relatively low strength and weight compared to other metals.Development stages of the steel industryTo continue answering the question, when was steel invented? What is the development history of steel? Let's study the development stages of the steel industry below.Early stageThe steel industry began to form in the late 19th century under the leadership of two leading developed countries, China and India. During this period, the steel industry was often produced manually, by forging or hand casting. This is the initial stage of the steel industry, when production methods have not been automated and the production scale is still small.In 1856, the birth of the Bessemer furnace helped steel production happen faster with cheap costs and large output. By 1865, Andrew Carnegie brought the Bessemer process to America, and from then on, America suddenly rose to the top of the steel industry.Historical period that saw a rise in steel makingAfter its infancy, the steel industry experienced a period of strong growth. During this period, steel production technology was improved, production processes were automated, and production scale increased. This leads to increased productivity, reduced production costs, and increased competitiveness in the steel industry. This is also considered a historical period that witnessed an increase in steel making.Steelmaking by BOF blast furnaceAt the beginning of the 20th century (1970s), many wars occurred. Leading to increased demand for steel to serve the needs of manufacturing and producing weapons and tanks. Western countries entered the stage of industrialization and modernization. Since then, the demand for steel has increased dramatically to serve the construction of infrastructure projects and buildings. From here, the appearance of "Oxygen Blowing Furnace (BOF)" and "Electrical Arc (EAF)" technology has created a major turning point for the development of the steel industry.Saturation phaseAfter going through a historical period that witnessed an increase in steelmaking, the steel industry entered a period of saturation (from the 1980s until now). During this period, the steel industry was able to balance supply and demand, and the growth rate gradually slowed down. Businesses in the industry are forced to expand their markets and seek new development opportunities to ensure continued growth and competition. However, the history of steel is still in the development stage, and we are aiming for more sustainable goals in the future.China currently dominates the global steel industryThe role of steel in today's lifeIt can be said that there is no field that does not use steel; steel is present almost everywhere. With the invention of steel and its durable and flexible properties, steel is known as an extremely important source of raw materials and is widely used in life, especially in the construction field. Below, let's learn about some of the roles of steel in today's life.The role of steel in constructionWith tough properties and the ability to be easily shaped at high temperatures. Steel invented has replaced iron, making it an indispensable material in the construction industry to increase the solidity and durability of projects. An important application of steel in construction is to use it to make reinforced concrete and house foundations, bringing stability to each project. In addition, steel is also used to build infrastructure, roads, public works, and transportation to serve the needs of the community. And until today's rapid development, there is still no material that can replace steel.The role of steel in everyday lifeBesides being an important element in construction, steel is also used in everyday life. From household products such as kitchen utensils and thermos bottles to interior decoration equipment such as tables, chairs, stairs,... With the invention of steel, people's lives have become easier, more modern and smarter.Household appliances are made of stainless steelAG真人游戏 Steel - Vietnam's leading steel supplierAs one of the pioneers in exporting Vietnamese steel, AG真人游戏 Steel is proud to always bring the best-quality steel products to customers.

Carbon steel is steel made of iron and carbon with some other ingredients such as manganese, silicon, phosphorus,... Let's delve deeper into the characteristics, applications, and important aspects of this type of steel with AG真人游戏 Steel.Carbon steel is among the top 4 most popular types of steel, used in many fields such as industry, manufacturing, civil use,... because of its flexibility and hardness.The more carbon in the steel, the higher the hardness and durability of the steel, in which carbon steel components can contain up to 2.1 wt.% carbon. The relatively low production cost of carbon steel makes it more preferred over other types of steel. Below, AG真人游戏 Steel will explore with you the pros and corn, production methods and applications of carbon steel.Carbon steel is steel made of carbon along with other elementsWhat are the different types of carbon steel?Carbon steel is categorized into three types based on its carbon content:Low carbon steelLow carbon steel has a carbon ratio of 0.04 - 0.25% or 0.29% with small amounts of other elements. Therefore, steel has low hardness and durability, so it is also called mild steel. However, they exhibit good ductility and can be easily shaped by pressing or bending, even when cold-formed.Medium carbon steelMedium carbon steels with average carbon content (0.25 - 0.5%), providing good corrosion resistance and high durability. Medium carbon steel has good heat treatment and cutting performance but poor welding performance, requiring preheating in welding. This type of steel is mainly used in high-strength moving parts such as air compressors, pump pistons, turbine blades, gears, crankshafts, rollers,...High carbon steelThanks to the carbon content of 0.6 - 2%, high carbon steel has good bearing capacity and high durability. The hardness of this steel can be up to 60 - 65 HRC according to Rockwell C. High carbon steel is mainly used in the production of springs, wear parts and high-hardness tools.Each type of carbon steel exhibits unique properties and applicationsWhat is carbon steel made ofCarbon steel is primarily made up of iron and carbon, combined with a number of other ingredients such as manganese, silicon, phosphorus,... In which, the carbon content determines the mechanical properties and durability of the steel. If the amount of carbon is low, the plasticity is high, convenient for shaping, bending and vice versa. However, the hardness and brittleness of the product depends on the metallurgy and heat treatment process. The carbon ratio can range from 0.02 - 2.1% depending on the amount of steel but the common ratio is 0.1 - 0.3%.Pros and cons of carbon steelAdvantagesEach carbon steel type has unique mechanical properties when undergoing metallurgy and heat treatment. Manufacturers can adjust technical parameters to create outstanding advantages for carbon steels as follows:High durability and hardness: High carbon content enhances the steel's bearing capacity and resists environmental impacts.Corrosion resistance: Carbon steel has extremely good corrosion resistance, so it is often used in the chemical, petroleum and marine industries.Good bending and melting ability: The amount of carbon can be easily customized to help the steel have flexibility for shaping, which is crucial in manufacturing and construction processes.DisadvantagesCarbon steel still have some disadvantages such as:Easy to rust: Manufacturers often add about 10-12% chromium to the composition, which acts as a moisture-proof layer to help limit rust when exposed to the environment.Poor aesthetics: Carbon steel lacks the smooth, shiny surface like stainless steel. Therefore, they are often applied to products that do not require high aesthetics such as pipes, machinery, spare parts,...Carbon steel strength helps it be applied in many areas of lifeHow is carbon steel madeCarbon steel can be produced from iron ore, scrap steel or a combination of both without losing its properties and strength. By heating iron ore and coke in the absence of air at a temperature of about 1650 degrees Celsius, the molten iron is enriched in carbon from the burning coke. The remaining impurities combine with lime to form slag, which floats on the metal surface to be removed. The product initially contains approximately 4% carbon, which is then decarbonized to reduce it to the desired level. Decarbonization occurs by passing oxygen through the melt forming monoxide and carbon dioxide.Applications of carbon steelsPossessing many outstanding properties, carbon steel is a material widely used in many different industries, typically:Road and bridge construction: Carbon steel has good corrosion resistance and high durability, suitable for building infrastructure such as roads, bridges, buildings, tunnels,...Automobile industry: Carbon steel is an ideal material for car parts such as vehicle frames, wings, hoods, exhaust pipes,... because of its high hardness, lightness and durable structure that helps reduce weight and increase space efficiency for vehicles.Aerospace industry: With its lightweight properties and outstanding mechanical strength, carbon steel is used in the production of aircraft components, spacecraft bodies and rockets.Oil and gas industry: Carbon steels are used to produce equipment and oil pipes thanks to its good bearing capacity. This will ensure the safety and performance of pipeline systems under the harsh conditions of the oil and gas industry.Manufacturing and machinery industry: Carbon steel has ductility and flexible shaping, so it is suitable for processing and producing machine parts such as shafts, bearings, gears,...Carbon steel's resilience makes it ideal for infrastructure, vehicles, and machineryImport the best quality Vietnamese carbon steel at AG真人游戏 SteelAccording to Worldsteel, Vietnam ranked 12th in the world in crude steel output with 19 million tons in 2023 and belongs to the group of steel exporting countries with a turnover of over 10 billion USD.

Stainless steel is one of the most popular materials in construction and civil manufacturing fields. Because of its durability and higher aesthetic properties compared to most other materials, the stainless steel production process is also quite complicated.History of stainless steelStainless steel is closely associated with the name of a British steel industry expert - Harry Brearley. He invented a special type of steel that has strong resistance to corrosion and rust by adjusting the Carbon and Chromium content appropriately.During the production process, Harry Brearley researched and added 8% Ni and 18% Chromium, successfully creating the 304 stainless steel grade that is very popular today. Because of its outstanding strength, stainless steel is widely used in many industrial and civil sectors.Understanding the stainless steel production processThe preparation of raw materials is the first factor that determines the success of the stainless steel production process. The elements iron, chromium, carbon, manganese,... are processed to remove impurities, ready for the next steps.Melting and castingSteel and alloy metals are added to an electric arc furnace and melted at temperatures above 2800 degrees F for continuously 8 -12 hours so that the metal completely turns into liquid. During the melting process, experts must regularly check the temperature and chemical composition so that the finished products are as desired.After completely melting the metal, the liquid mixture is crystallized with argon and oxygen to remove impurities such as sulfur, excess carbon and slag.To increase product applicability, refined steel is cast into billets, plates, bars,... or different shapes to suit all applications.FormingMost cast steel is shaped by hot rolling into sheet form while the billet is heated and rolled through a large roller to form steel plates, strips or bars.In addition to hot rolling, billets can also be cold rolled to form custom-sized steel blocks. Cold rolling typically uses small diameter wheels to produce a smooth, shiny surface with the smallest tolerances.Heat treatmentStainless steel is heat treated by heating and cooling under controlled conditions to relieve internal stress and soften the stainless steel. However, this stage requires strict control of the annealing temperature to ensure the quality of the stainless steel interior.DescalingAfter annealing and rolling, stainless steel still has a layer of oxidized residue on the surface. The factory needs to clean off the residue to restore the shiny surface of stainless steel. Currently, nitric acid and hydrofluoric acid are the most popular descaling agents. In addition, the electrolytic method is also used to remove residue from the surface.Stainless Steel TemperingThe purpose of heat treatment of steel is to increase the hardness and durability of the material. After annealing, stainless steel tends to become softer. When tempering steel, factories often use water because of its low cost and quick cooling effect. First, experts heat the material to about 815 - 900 degrees Celsius, then transfer the alloy to a water bath to suddenly reduce the temperature, maximizing hardness and durability.Cutting and machiningAfter the above processing steps, stainless steel is almost complete and can be manufactured into various industrial applications. In this step, the factory can cut and process steel into different shapes and sizes by cutting, sawing or techniques such as plasma, high pressure water jet,...Surface finishingStainless steel is famous for its high aesthetics and outstanding corrosion resistance, ease of cleaning and high applicability. To achieve these properties, stainless steel needs to be surface finished by annealing, hot rolling, cold rolling, grinding, polishing, sandblasting,...Methods of controlling stainless steel quality after productionAfter production, stainless steel needs to undergo a number of quality tests before being distributed to the market.Mechanical testMechanical testing measures the physical capabilities of stainless steel such as load-bearing capacity, stress, tensile strength, Brinell, toughness,...Chemical testingChemical testing aims to check whether the chemical properties of stainless steel meet standards through spectroscopic analysis. Besides, factories also test and measure the corrosion resistance level of materials by spraying salt water.If you have any questions or need to import Vietnamese steel, please contact AG真人游戏 Steel via Email: [email protected] or Hotline: +842836223358 for the most thoughtful support!

As a material used in most fields, the steel refining process is of great interest. Join AG真人游戏 Steel to learn more about the steel refining process in the article below!1. Iron Ore Processing: The First Step in the Steel Refining ProcessThe first stage in the steel refining process is to process iron ore and other metal components to make steel. Iron ore includes a lot of minerals, the processing of which will help remove impurities to obtain the main ones.Usually, iron ore will be mined in mines in areas with high mineral potential. When put into the kiln, iron ore will be added to other additives such as limestone, coal,...2. Create a stream of molten steelAfter being processed, the steel refining process begins with the introduction of iron ore from the top of the blast furnace, hot gas is blown from the bottom. After being heated at 2000掳C, the iron ore will transform into molten steel. During this period, steel usually appears as black steel. Black steel hides carbon, sulfur, silicon as well as many other impurities.After obtaining the finished product, the steel will be directed to the smelters. At this time, the molten steel is processed, removing the remaining impurities during the heating process. From there, creating a correlation between chemical components in the steel refining process.3. The next fuel castingThe finished steel of stage 2 is sent to the billet furnace; after being cast, there will be three basic types of billets:Bar workpiece: workpiece with a cross section of 100x100 or 125x125, length 6-9-12m. Usually used for rolling or pulling steel coils as well as rebar steel.Slab: Usually use rolled-out hot-rolled steel coil, hot-rolled steel plate, cold-rolled steel coil or shaped steel.Bloom billet : Used to replace bar or slab workpieces.In the process of steel refining, after being cast, the workpiece is in two states: hot and cold. In particular, the hot state will be maintained at a high temperature and then taken to the hot rolling place. On the contrary, if it is in a cold state, the billet is transferred to other factories, reheated and then transferred to the rolling process to form the product.4. Finished products of steel refining process: Hot rolled coil and cold rolled coilIn the steel refining process, at the 4th stage, billets are sent to factories to roll out different construction steel products:Bringing a billet into the steel plate factory to roll out cast steel plates.Put the billet into the hot-rolled coil factory, and the billet will be rolled into a hot-rolled coil.Bringing billets to the section steel mill to roll out rail products, U, V, I, H and bar steel products. Bringing billets to steel mills to roll out smooth construction coils. If you want to roll out a cold-rolled coil, the coil temperature will be lowered to an appropriate level. Then pass through the rust removal line and proceed to roll with the required thickness and size. At this time, the cold-rolled products will have a brighter, more glossy and harder surface. 5. Galvanized steel coil and steel pipeAfter the steel refining process, the cold-rolled steel obtained in stage 4 will undergo galvanizing to finish the coil surface. The zinc coating protects the steel against corrosion and increases the life of the product. Galvanized steel coil is the raw material for the production of steel pipes. In addition to steel pipes, galvanized steel coils are also used to produce Square Steel Pipes, Steel Rectangular Pipe,... with diverse designs and sizes.Above is the steel refining process made from ore that is applied in most factories.

Today, environmental protection is one of the main goals of all activities and businesses aiming at sustainability, stability and community value. In addition to ways such as limiting the use of plastic and not littering, recycling steel is also one of the solutions that many people trust, especially in the construction industry. In this article, AG真人游戏 Steel will analyze efforts to reduce the environmental impact of steel products throughout its life cycle of steel, from raw material exploitation to end-of-life stage.1. Recyclability of construction steelSteel is one of the most recycled materials in the world with 93% of all structural steel capable of being recycled into new products without losing its inherent properties, while only 8% of plastic is recycled. When using recycled steel, the production process can reduce electricity consumption by 80% compared to completely new production, while also reducing environmental impact and completely eliminating the exploitation of raw materials.During the life cycle of steel, materials are recycled and used in many large and small projects with the construction method of prefabricated steel frames. This is a construction solution chosen by many investors because of its outstanding advantages such as saving time, labor costs, shortening the disassembly and assembly process,...2. What is the life cycle of steel?By understanding the life cycle of steel, we can take advantage of its infinite reusability to create sustainable economic and environmental values.Collecting raw materialsFor recycled steel, you can find sources such as factories, shipyards, large construction projects, ships,... around the world. This process also includes classifying and separating scrap steel from mixed materials so that the recycling process takes place quickly, minimizing residue. Steel productionSteel factories focus on two common production processes: producing steel from iron ore in blast furnaces or from scrap in electric arc furnaces. With advanced technological improvements in production lines, CO2 emissions are reduced during the production phase.Recycling leftover productsDuring the steel production process, there will be surplus products that can be reused such as slag, iron scrap,..., which act as a substitute for some raw materials, used for the next production stages. This both reduces waste into the environment and saves significant costs and time for production processes throughout the life cycle of steel.Production of finished productsHigh-strength steel has superior properties compared to conventional steel structures because of its extremely good durability, impact resistance and corrosion resistance. Therefore, projects that require high bearing capacity such as factory frames, warehouse steel frames, cars,... often use high-strength steel to consume less material, optimize weight while still ensuring durability, safe in use.Steel recyclingFinally, steel returns to its life cycle as post-consumer scrap. At this point, it has already finished its first life cycle and is ready to be recycled to begin the life cycle of new steel.Steel is an industrial material that is recycled many times but still retains its properties, so there is no need to worry about reducing durability and safety when used for projects. Steel recycling not only contributes to reducing industrial waste in the world and protecting the environment, but is also a cost-effective solution for investors. Thus, steel scrap can be 100% recyclable and continues to exist forever throughout the life of the steel.3. Some examples of the life cycle of steelSteel is not only an environmentally friendly material but also an economical construction solution. The structures themselves can be constructed from many different types of recycled steel. Let's consider with AG真人游戏 Steel which common applications best represent the life cycle of steel.AutomobileMost of the car's structure is made from steel, so after long-term use, even though the car loses its usability, it can still be recycled. Currently, automotive steel is the largest source of recycled steel in the United States. After processing, this material continues to be used in the automobile manufacturing industry with durability and an average lifespan of up to 15 years.Packaging and containersOne of the most common uses of steel that few people know about is packaging of goods. Food, wine, paint, crude oil, etc. are often preserved and transported in steel tanks to ensure product safety and quality when it reaches the user. Recycled steel is not only used to make containers, belts, etc., but can be manufactured into large containers and then recycled during the life of the steel to make other applications.Steel structureThe use of wood as a building material can deplete natural resources, cause environmental disasters and cannot be recycled or recovered. Wood structures also generate more industrial waste, so steel structures are becoming increasingly popular in housing construction. Not only do they bring modern, sophisticated, cost-effective aesthetic beauty, but steel buildings can be completely recycled after they stop being used.Infrastructure projectBesides housing, steel is also the main material for projects such as bridges, roads, railways, silos, tanks,... Thanks to its high strength, steel is used for frames or roofing, providing high durability and ability to bear large loads. These structures, after long periods of use, may become degraded or need to be removed. At this time, steel materials can be recycled and used as materials for completely new projects, starting a circular steel life cycle.

The most important factor of a sustainable building is the source of quality construction steel. Depending on the property of each project, the contractor will choose some criterias to evaluate construction steel. Below is a list of common criteria for evaluating the quality of construction steel.Construction steel quality standardsThere are countless different types of steel on the market today, in order to create a common uniformity in the steel production process, quality standards have been issued. Manufacturing mills will often rely on these quality standards to adjust the specifications to ensure the quality of the steel grade is in the best condition.Three common quality standards including Vietnamese, American and Japanese standards are applied to steel constructions such as plain bar and rebar. In which, when the product meets Vietnamese standards, construction steel is considered as standard steel and is completely suitable for construction projects.TCVN - Vietnam steel standardVietnam confirms quality standards for steel grades is abbreviated in the form of TCVN, of which there are 4 general standards: TCVN 1651-1:2008, TCVN 1811_2009 (ISO 14284-1996), TCVN 6287_1997, TCVN 7937-1-2013.The plain bar steel used to make reinforced concrete and on each of them are marked CB240-T, CB300-T and CB400-T. Similar to plain bar steel, rebar steel also owns 3 standard steel grades including CB300-V, CB400-V, CB500-V, CB600-V. The numbers in the symbol will represent the strength of the steel. Specifically, the CB300-T series will indicate the value of strength is up to 300N/mm2, meaning that a steel bar with a cross section of 1mm2 will withstand a tensile force of up to 300N (equivalent to 30kg).ASTM - American steel standardThe American Standard is identified by its common abbreviation ASTM, will focus on key topics such as specifications, testing, and grading guidelines. The American standard applied in the current range of construction concrete steels is ASTM A615/A615M with 3 steel grades including GR40, GR60 and GR75.Most steel grades according to American standards are highly appreciated for their outstanding hardness when all 3 steel grades GR40, GR60 and GR75 possess tensile strengths of 420 MPa, 620MPa and 695MPa. Having the high tensile strength will be a plus point of this standard for building framing applications because they provide extremely good loading.JIS - Japanese steel standardThe Japanese standard is also one of the familiar standards in the steel industry with the abbreviation JIS. Currently, two popular Japanese standards are applied in construction steel including JIS G3505 - 1996, JIS G3112 - 1987.Construction steel specificationAnother important criterion in the selection of construction steel is the appropriate size including diameter, length and volume. Knowing the construction steel diameter will help the contractor easily calculate the required volume of construction steel for the project, especially for large projects that always require meticulousness and calculation in detail.If the contractor is not careful in choosing the right size, it is easy to make the structure weak because of unbalanced transmission forces in some loading parts. Famous construction steel suppliers in the Vietnam market such as Hoa Phat, Pomina, Viet Italy, ... are at risk of being faked as poor quality versions. Normally, the fake version of construction steel will have a smaller size from 0.5 - 0.8mm than the authentic one.Specification of steel standard TCVN 1651-2008Outside diameter桅6桅8D8D10D12D14D16D20D25D32D36D40D50Cross section(mm2)28.350.2750.277.8511315420131449180410181 2571 694Specific weight (kg/m)0.2220.3950.3950.6170.8881.211.582.473.856.317.999.8615.42Tolerance specific weight (%)卤8卤8卤8卤6卤6卤5卤5卤5卤4卤4卤4卤4卤4 Specification of steel standard JIS G3112 - 1987Outside diameterD10D13D16D19D22D25D29D32D35D38Cross section(mm2)71.33126.7198.6286.5387.1506.7642.4794.2956.61140Specific weight (kg/m)0.560.9951.5592.2493.0393.9785.0436.2347.5098.949Tolerance specific weight (%)卤6卤6卤5卤5卤5卤5卤4卤4卤4卤4 Specification of steel standard ASTM A615/ A615M-08Outside diameterD10D13D16D19D22D25D29D32D36Cross section(mm2)711291992843875106458191006Specific weight (kg/m)0.560.9941.5522.2353.0423.9735.066.4047.907Tolerance specific weight (%)卤6卤6卤6卤6卤6卤6卤6卤6卤6 Steel origin and the market priceThe standard steels must be the steel lines having clear origin, usually the manufacturer will attach labels showing characteristic symbols and brand names on each steel bundle.In addition, quality construction steels from reputable brands will always have a fixed price and the retail price will be listed from the manufacturer. If the price of steel is too low compared to the factory's selling price, it means that the quality of the steel will not be guaranteed.Quality construction steel must come from a reputable supplierBesides considering the quality criteria, choosing a reputable steel supplier is also an important factor to help get good construction steel.

For decades, metal corrosion problems have always been one of the challenges for steel manufacturers. The making use of a steel coating method to create a protective layer for the steel core is considered the most effective process. Currently, there are many methods of steel coating and these types possess different characteristics with advantages.The role of the steel coating method for the durability of productSteel is a product derived from metal ores, so wear and rust will occur if we leave them for a long time in the environment. Therefore, manufacturers often conduct steel coating stages before putting them on the market to create a protective layer for the steel surface to help resist external effects.Prevent rust and oxidizing agentsZinc components present in the coating layer when exposed to oxygen and carbon gas, it will form a layer of zinc carbonate (ZnCO3). Thanks to this chemical reaction, the steel core can minimize approaching oxygen, thereby avoiding corrosion and rust.Keep the surface of the product in top conditionCoatings not only strengthen the steel, but they also support the surface of the product in its best condition by resisting scratches or chipping.Improved loading capacity Steel coating method can help enhance the loading capacity of steel, which has been proven by several studies. Specifically, components such as aluminum, chromium can increase the mechanical properties of steel when they can deposit crystals through the surface, thereby playing a role in increasing the solidity.Savings cost for long-termAlthough galvanized steel products will have a high initial cost, in terms of long time for use, they help optimize costs significantly. Thanks to the durability as well as the limiting surface oxidation, users will not have to spend a lot of money on maintenance as well as replacing new products periodically.5 most common steel coating methods in the manufacturing industryAll current steel products before being put on the market will have to go through steel plating stages to improve durability. Currently in the steel manufacturing industry, manufacturers often apply 5 common coating steel methods and each method has its own characteristics and different applications.Hot dipped galvanizedGalvanizing method mainly refers to dipping the steel into a hot zinc bath. Through this method, the outer layer of the steel is melted into an alloy with zinc under high temperatures of up to nearly 500 degrees Celsius. As soon as the zinc and steel start to react with each other, the operator will put them out of the tank and let it dry, normally hot dip galvanizing will take place within 30 to 40 minutes.Thanks to dipping the entire steel into the zinc solution, the steel coatings are completely wrapped around the surface as well as firmly adhered to the core steel layer, making the zinc layer difficult to peel off. The hot-dip galvanizing method is used by many manufacturers because it brings high economic value along with simple practical operation and does not require much technical calculations.Steel coating method with electrogalvanizationContrary to hot-dip galvanizing, electrolytic galvanizing will not directly immerse the product in a hot zinc bath, but the manufacturer will use equipment to spray zinc solution directly on the steel. Spray solutions contain a large amount of zinc ions with a positive charge while the surface of the steel product has a negative charge, when the two charges approach together, they will form an extremely tight zinc coating.Usually the product will be hung or carefully positioned to make the handler spray the solution in the most convenient way. The first special feature of the plating process is that it takes place quickly, it's only about 5 or 10 minutes. Electrolytic steel coating method is considered to be quite safe when the handler does not have to be exposed to high temperature solutions, limiting dangerous incidents. The most common application of this method is mainly in electronic components or interior decorations.However, the electrogalvanization method produces a coating that is neither thick nor evenness compared to the hot-dip galvanizing method. In addition, the average thickness of electroplating is about 15-20 micrometers. Although electroplating products still maintain good rust and oxidation resistance, they are inferior to other products, especially products coating by hot dip galvanizing process.Thermal sprayingThermal spraying is a term that refers to the steel coating method with molten liquid droplets that form a mist over the surface. Coating materials usually exist in powder or wire form, then they will be heated through fire, plasma jets or electric arcs, when the material reaches a molten state, it will be sprayed directly onto the surface. Under the influence of heat energy and electrical conductivity available in the material, the solution particles stack on top of each other and adhere to the steel surface.Thermal coating will help steel reach an ideal plating thickness from 20 micrometers to several millimeters depending on the needs of the manufacturer. By providing a wide range of coating thicknesses, thermal spray coating can be applied to a wide range of materials from steel, stainless steel, nickel alloys to plastics and ceramics. Even steel products possessing complex surfaces can be completely uniformly heat-coated thanks to modern robotic manipulation applications.Thermal spray steel coating method is considered an advanced method in the plating process that promises to bring a lot of convenience to the manufacturer along with a thick and uniform coating for the product. However, the method will require manufacturers to spend high initial input costs due to technological requirements.Powder steel coating methodPowder coating is a popular coating technology today with the principle of using electromagnetic force to make the paint adhere to the surface of the steel layer. The manufacturer will take advantage of the negative electrical charge on the steel surface, but use a mixture of paint powder with a positive charge to create a strong bond to help the paint layer adhere and spread evenly throughout the surface.It is thanks to this physical principle that the powder coating method will give better results than conventional coating. Powder coating is well known for providing products with a thick and smooth finish, providing a high gloss finish to the product's appearance.Although powder coating brings durability along with highly aesthetic color to the product, it consumes a considerable amount of input costs. The powder coating process requires manufacturers to own spray booths and specialized spray equipment to perform, so this method will not be feasible for small manufacturing businesses.Paint coatingThe last steel coating method mentioned in today's article cannot mention the paint coating process. In order to create a protective coating on the surface of the product, the manufacturer will perform 3 layers of paint including: primer, intermediate coat and top finish paint. Weather conditions will also significantly affect the paint, so the right temperature for the paint to be durable and beautiful is usually between 10 degrees Celsius and 35 degrees Celsius.The implementation of the paint coating method not only helps protect the steel surface from harmful agents from the environment, but also creates an aesthetic appearance with outstanding colors. Although the durability of the coating method will not be better than the other methods, they are highly appreciated in supporting the cost of input materials, this plating method is extremely suitable for most businesses in both small and medium scale.The steel coating method has appeared and become popular for a long time in the manufacturing field because it acts as a protective shield for the steel core. The above article lists the top 5 most popular steel coating methods today along with the advantages and disadvantages of each method.
