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.

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.

Pre-engineered steel buildings are becoming increasingly popular in construction projects due to their superior advantages over traditional concrete steel buildings. Let's MRS Steel explore this type of building and its pros and cons in today's article.1. Overview of prefabricated steel buildingsPre-engineered steel buildings refer to a type of house or facility constructed based on pre-manufactured steel components. Once these parts are produced, the construction team transports them to the site for assembly and completion. The entire construction process of a pre-engineered steel house goes through three main stages: design, component fabrication, and on-site assembly. Because of using available steel structures, the construction is faster and requires less manual labor.Compared to traditional houses, pre-engineered steel buildings have a distinct structural system. The main structure includes steel columns and beams designed to bear the load for the walls and roof. Regarding the foundation, which is the primary load-bearing base for the house, the pre-engineered steel homes still use reinforced concrete for their foundation. However, depending on requirements, one can choose for shallow or deep foundations. The supplementary structural system, which enhances the house's completeness, includes partitions, stair-support frames, and roof trusses made from C, Z, or I-beams.The roofing structure is typically made of metal sheets to shield the house from environmental and weather impacts. Commonly, the favored material for these roofs is PPGI/PPGL because of its excellent corrosion resistance and high heat tolerance.2. The outstanding advantages of prefabricated steel buildingsPreviously, prefabricated steel buildings were mainly used for constructions like warehouses, workshops and exhibition halls. However, in recent years, this type of building has become popular for residential purposes due to its flexibility, time efficiency, and affordability.2.1. Cost savingsThe steel houses generally have a lower construction cost than traditional concrete houses. This is because the number of materials used to construct the house is significantly reduced, mainly relying on columns, beams, and trusses for main structural support. Additionally, steel is a durable material, and the anti-rust and oxidation properties coming from galvanized steel can help reduce maintenance costs.2.2. Quick on-site constructionThe design, assembly and construction process of these houses is faster, more precise, and safer than traditional building methods. Main components like columns, beams, and steel bars are pre-manufactured in factories, so when these components are transported to the construction site, the assembly team simply follows the provided instructions.All processes such as cutting, drilling, welding, hole punching, and anti-corrosion painting are performed in the factory by using automated machinery. This means that measurements and quantities are pre-determined based on technical drawings, eliminating direct handling at the construction site and reducing technical errors and safety risks. A small prefabricated steel building can be completed in just a few weeks or even some days, while traditional houses can take several months to finish.2.3. High flexibilityUnlike traditional houses, which are permanent, the steel houses can be easily moved to another location. The structural components are connected with bolts and screws, allowing for easy disassembly and relocation.2.4. The prefabricated steel buildings are a type of multi-purpose houseOne of the outstanding advantages of these buildings is that they do not occupy too much space due to their compact structure. With just the addition of some furniture and fixtures, a comfortable living space can be created. Moreover, this type of house can serve multiple purposes across various sectors, including industrial, commercial, and residential.3. Looking for unit bring steel solution for your prefabricated steel building projectThanks to its flexibility and convenience in construction, as well as its cost-effectiveness, it's considered a solution that overcomes the drawbacks of traditional concrete houses. However, it's worth noting that the prefabricated steel buildings may be less sturdy than concrete houses due to their features such as reasonable costs, versatility, and convenience for various models. Therefore, to build such a house, contractors must find stable ground along with a mild climate to achieve better efficiency.While there are some concerns about sturdiness, selecting quality steel sources from the beginning process for the structural framework can significantly enhance the durability of this type of house. Therefore, choosing companies specialized in steel solutions will bring benefits to pre-engineered steel house construction projects.MRS Steel, with its extensive experience in the steel industry, is your ideal partner for prefabricated steel buildings projects.
