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 MRS 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, MRS 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 MRS 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.

Vietnam's steel industry has made remarkable developments in both production scale and technological lines. Vietnam steel quality has gradually reached important markets such as Europe and America. Today MRS Steel will make an overview of Vietnam quality steel as well as learn about breakthroughs in the country's steel production technology.Vietnam steel quality based on breakthroughs in steel refining technologyPreviously in Vietnam, most steel was produced through electric arc furnace (EAF) technology, but the EAF method was assessed to cause high electricity consumption. In addition, input materials such as iron ore or scrap steel contain too many impurities, which has generated more dust and large slag in the production process, reducing the furnace's life span and affecting the quality of the output steel.In the period from 2010 to 2020, many domestic steel enterprises have installed blast furnaces with large capacity, specifically Hoa Phat has operated 2 blast furnaces with the capacity is 1,350 m3, Formosa Ha Tinh has installed blast furnace No. 1 with a capacity of 4,350m3 and blast furnace No.2 with a capacity of 4,350m3. The improvement of furnace capacity has helped manufacturers minimize dust emissions, eliminate harmful impurities and reuse energy through coal gas recovery to produce thermal energy for the furnace.In addition, the large manufacturers such as Hoa Phat, Formosa or VN Steel,... have installed the technology of basic oxygen furnace (BOF) or the LD converter into manufacturing activities. In particular, the technology of BOF has a significant effect in burning all impurities in liquid iron and the steel scrap. Specifically, Hoa Phat's output steel has the percentages of impurities (Cu, Ni, Cr). ) is very low when less than 0.03% and this figure is lower than the standards of many countries in the world. Based on an extremely low impurity rate, the output steel product will achieve purity and consensus in quality, the steel will have good bending properties, combined with toughness and high yield strength will improve the sustainability of construction.Continuous investment in steel production linesDuring the past 10 years, the domestic steel manufacturers have continuously invested in steel refining technology as well as improved modern techniques in production lines in order to bring more Vietnam steel quality to the abroad markets. Currently, most steel producers in Vietnam such as Hoa Phat, Hoa Sen, Ton Dong A, Nghi Son, ... all use the most advanced steel production lines in the world such as Danieli - Tenova from Italy,  SMS from Germany,...Most of the galvanizing or color coating lines in Vietnam are equipped with gas recovery systems to help manufacturers save energy. Another highlight of these technologies from Europe is low operating costs as well as high flexibility when it can be applied to many types of steel products as well as can accept many different coating materials.For example, the CM4 color coating line of Ton Dong A is equipped with an RTO gas recovery system to help protect the environment or Hoa Sen Group's galvanizing line is equipped with an electric annealing furnace to help reduce waste of gas emissions from the factory. In addition, the color coating lines are also equipped with NOF annealing furnace technology to help the galvanized layers adhere to the steel better, assisting manufacturers to control the exact thickness of the layers, optimally treating temperature of flatness and gloss of the finished product.International standards for output productsCurrently, Vietnam steel quality products have reached many countries around the world including large markets such as Europe, America, Australia, etc. The equipping of advanced production lines has helped domestic steel manufacturers qualify to produce quality steel grades in terms of size, weight, ductility, and bearing capacity. Before being exported, steel products are fully certified standards including JIS of Japan, ASTM of America, BN of UK, AS of Australia.Besides, the quality management system standards at factories are also an important factor to evaluate the quality of output products. Most of the domestic steel factories come from corporations such as Hoa Phat, Hoa Sen, Ton Nam Kim, Ton Dong A, Vn Steel,... all obtained the certification of the latest standard ISO 9001:2015, which partly shows the production capacity and resources of the enterprise.Finding the reputable supplier of Vietnam steel qualityVietnam's steel industry in recent years has made amazing changes as it has gradually become self-production with a wide range of steel products.

The trend of using steel in the warehouse industry is becoming increasingly popular, ranging from constructing warehouse structures, canopies, to storage racks. In the warehouse industry, factors such as efficiency, durability, and cost-effectiveness play a crucial role, and steel is the material that can comprehensively meet these criteria, as outlined in the reasons in the following article.The durability of structures are enhanced through steel in the warehouse One of the reasons why steel is increasingly preferred and widely used in the warehouse industry is its durability and its ability to provide structural integrity. Especially in storage racks, a robust frame system is essential to support the load when storing a large quantity of goods for an extended period. Racks need a certain level of rigidity to avoid bending or deformation under the weight of the goods, and high-strength steel types contribute to ensuring the required stiffness and stability of the racks.The warehouse industry always demands long-term storage, where durability is crucial in facing the challenges of time. In regions with high humidity, fog, or near the sea, steel may encounter challenges from salt and oxidation. However, manufacturers can address this issue by applying additional layers of zinc coating to protect the steel surface and enhance the lifespan of storage structures.Flexibility in design helps expand storage space for goodsSteel with a certain level of flexibility brings about versatility in shaping and designing. Specifically, steel can be easily processed and designed in various sizes and shapes. This enables manufacturers to construct multi-tiered racks that are tall and vaulted without compromising stability. Additionally, the ability to extend the length across spans helps optimize the storage space for goods.Modern warehouses are typically categorized based on various storage needs, such as cold storage or distribution centers. Thanks to the ability to be processed in various forms, steel racks can meet diverse design requirements, for instance, catering to the low-temperature storage needs of cold storage facilities or optimizing storage space for distribution centers. Importantly, steel rack systems offer an open space within the warehouse, enhancing integration with automation systems, robots, and other smart devices to optimize the transportation, handling, and storage processes for goods.Using steel in warehouses helps save installation and regular maintenance costsIn the warehouse industry, cost-effectiveness is considered a paramount factor, and steel is an extremely suitable material for cost-saving solutions during both installation and regular maintenance. Typically, steel components are manufactured and shaped according to customer requirements in the factory. They are then transported directly to the delivery location, and the warehouse section only needs to arrange suitable installation locations. Utilizing pre-prepared components helps minimize installation time, allowing warehouse management to reduce labor costs and expedite project completion, enabling the warehouse to start operations sooner.In addition to its rigidity, one of the primary characteristics of steel is its excellent corrosion resistance, especially in the case of galvanized or stainless steel. Although the initial cost of installing steel components is considerably higher than that of other materials, the durability that steel provides helps management significantly save on fixed costs. The good corrosion resistance implies a reduced likelihood of deterioration, leading to a decrease in annual maintenance costs and limiting the frequency of repairs or replacements for components.Ensuring safety through fire resistanceWarehouses are crucial for storing goods, making safety within these spaces of utmost importance. Specifically, the ability to resist fire and moisture becomes a crucial factor in ensuring the safety of stored goods. Unlike some other building materials, steel is fire-resistant and non-combustible. The metallic nature of steel helps prevent water from infiltrating the structure, providing an effective defense against moisture. The steel's impermeability reduces the risks of damage caused by water, protecting goods from mold or decay due to dampness.Even in the event of a fire or explosion, steel maintains the integrity of the structure better than other materials, even when exposed to high temperatures. This is critical in emergency situations, as steel can withstand temperatures up to 1000 degrees Celsius. The low flammability and high heat resistance allow warehouse managers additional time to respond to emergencies, prolong evacuation times, and limit potential damages.Using steel in warehouse components provides high load-bearing capacity, ensuring that storage racks can withstand significant weights without encountering undesirable deformations. The durability and safety of steel not only help maintain the structural integrity but also reduce maintenance costs and enhance corrosion resistance, making the warehouse system stable and sustainable over time. Through this article, we hope that viewers can gain a more objective perspective on the role and long-term potential of steel in the warehouse industry.If you are looking to import steel for your project and are unsure about choosing a reputable manufacturing plant to ensure quality, please contact MRS Steel for free assistance via email: vanloc@mrssteel.com.vn or Whatsapp: +84 76 911 2358.

Aluminum and stainless steel are the most common materials in manufacturing and metalworking industries. Both materials have their own advantages, and these important characteristics ensure the quality of the final products. In today's article, let's delve deeper into the differences between aluminum and stainless steel in metalworking and manufacturing applications with MRS Steel.Strength and weight ratio of aluminum and stainless steelAluminum is a lightweight and flexible material commonly used in metal fabrication. Specifically, aluminum has a cubic crystalline structure, making it a lightweight metal with a low density, around 2.7g/cm³. Thanks to this excellent strength-to-weight ratio, aluminum is often utilized in the production of lightweight products, such as in the aerospace industry, automotive industry, and applications requiring easy transportation.Stainless steel is an alloy of iron with at least 10.5% chromium. In contrast to aluminum, stainless steel actually has a weight three times greater than aluminum. The density of stainless steel typically ranges from 7.75g/cm³ to 8g/cm³, yet it provides significantly superior strength. In metalworking applications, the bending ability under gravitational force or thermal effects of this type of steel is evaluated to be comparable to aluminum sheets.Corrosion resistanceUnder normal environmental conditions, both aluminum and stainless steel exhibit good corrosion resistance. However, when facing harsh environments such as seawater or chemical exposure, the superior oxidative resistance of stainless steel is demonstrated compared to aluminum. Due to its significantly higher chromium content, stainless steel forms a protective chromium oxide layer through reactions with oxygen in the air, preventing direct contact of the metal with the external environment.Meanwhile, aluminum, when exposed to outdoor conditions for an extended period, can undergo oxidation if not protected by surface treatments such as coating or painting. The surface of aluminum may turn white or corroded due to factors such as moisture, oxygen in the air, and the impact of other chemical compounds. Particularly in environments containing acids or salts, aluminum can corrode rapidly and severely, causing damage to its structure and material properties.Aluminum has good thermal conductivity, stainless steel provides stability at high temperaturesIn contrast to its corrosion resistance, aluminum exhibits much better thermal conductivity than stainless steel. This property allows aluminum to transfer heat faster and more efficiently in applications requiring heat transfer, such as in the automotive, electronics, or aerospace industries.However, when it comes to heat resistance, stainless steel can be used at much higher temperatures than aluminum. Specifically, stainless steel can maintain stable mechanical properties and structure at high temperatures without deformation or loss of hardness. Thanks to its stability at high temperatures, this type of steel is used in industries requiring heat resistance, such as in chemicals, furnaces, or heat exchangers.Flexibility and machining capabilities between aluminum and stainless steelOne of the greatest advantages of aluminum is its flexibility. Aluminum is a very soft metal, easily shaped and formed into various shapes and sizes. This makes aluminum an ideal material for applications such as sheet metal fabrication, where complex shapes and designs are required.Stainless steel, due to its higher hardness compared to aluminum, is much more difficult to bend and shape due to its excellent corrosion resistance. However, concerning welding applications, stainless steel is relatively easy to weld because it has a higher melting point than aluminum, making the welding process more stable and less prone to issues such as sagging. Conversely, welding aluminum can be challenging as the welding process always requires specific techniques to avoid causing thermal distortion.Electrical conductivityStainless steel exhibits poorer electrical conductivity than most metals due to the chromium and nickel structures, which typically have high electrical insulation properties, making it unfavorable for electric current flow. Conversely, aluminum is an excellent electrical conductor, with high conductivity and lightweight, making it ideal for high-voltage overhead electrical wire applications.Although stainless steel has low electrical conductivity, it does not mean that it does not appear in electrical applications. Instead, stainless steel is often used in cases where non-conductive materials are needed to enhance the safety and electrical transmission efficiency of the core. Some specific examples of stainless steel applications in the electrical industry include outer casings of electrical equipment, as these components need to prevent electrical transmission.Aluminum and stainless steel are versatile materials with distinct advantages, and the choice between them depends on the specific needs and requirements of each project. If you need a lightweight and easy-to-machine material, aluminum may be the better choice. If you need a sturdy and durable material with high heat resistance, weldability, and an elegant appearance, stainless steel may be the better option.
