Stainless steel is a corrosion-resistant steel due to its composition, containing a minimum of 10.5% chromium. They possess many strengths and outstanding advantages that many conventional metals lack.In the article below, MRS Steel will analyze in more depth the characteristics of each type of stainless steel so you can better understand this versatile steel.The stainless steel composition plays a crucial role in determining the material's properties and applicationsWhat is stainless steel?Stainless steel is an alloy containing at least 10.5% chromium and a maximum of 1.2% carbon by weight, by mass. The chromium acts as a protective coating on the inner steel layers, preventing the impact of environmental agents on the steel structure. That is also the reason why stainless steel has high corrosion resistance, making it an ideal material for projects.Characteristics of stainless steelThe most outstanding feature of stainless steel is its ability to resist corrosion in different environments, including acidic and chemical ones. However, this does not mean that stainless steel will last forever. It is still capable of rusting and corroding under prolonged harsh conditions. The average lifespan of stainless steel is still many times higher than that of conventional steel, making it a premier choice.The manufacturer analyzed the stainless steel material to ensure its quality met industry standardsAdvantages of stainless steelCurrently, stainless steel is still one of the top priority materials in construction because it possesses many strengths as follows:- High corrosion and oxidation resistance ensure longevity and sustainability, reducing maintenance costs.- Recyclability without compromising its properties makes it an everlasting eco-friendly material.- Stainless steel has a bright surface, is easy to clean and also increases the aesthetics of the product.- Environmentally friendly and safe for users, it's a top choice in medical equipment, food processing and more.- High strength and melting point along with standard plasticity and hardness for the production of industrial equipment, machinery,...Application of stainless steelStainless steel is produced in coils, plates, wires, bars or tubes, so it can be widely applied in many fields:- Kitchen utensils, medical equipment- Construction materials in projects and works- Industrial equipment in chemical plants, oil refineries,...- Oil tankers, chemical and food storage tanks The application of stainless steel in various industries demonstrates its versatility and durability.Classification of stainless steelAmong thousands of different stainless steel alloys, there are 4 main types as follows:Austenitic stainless steelThis is the most common type of stainless steel with a much higher chromium content than other steel alloys so it is more resistant to corrosion. Another characteristic of this alloy is that it is magnetic after cold working.Ferritic stainless steelThe second most popular form of stainless steel after Austenitic is Ferritic. They have low nickel content so they are more cost effective but still retain the properties and strength of stainless steel. This alloy can be hardened by cold working to retain its magnetism.Martensitic stainless steelMartensitic stainless steel has a chromium content of 11.5 - 17%, 1.2% carbon and some other metallic elements. Martensitic steel has a low nickel content, so its corrosion resistance is weaker than other stainless steels. They are widely used in the field of medical instruments, mechanical valves, turbine parts, mechanical instruments, oil industry and many other applications.Duplex stainless steelDuplex stainless steel possesses both the strength of Austenitic and Ferritic steels by containing 50% of the physical properties of both steels. Duplex steel is the top choice for applications requiring durability, corrosion resistance and formability.The classification of stainless steel involves categorizing it based on its chemical composition, microstructure, and mechanical propertiesImporting affordable Vietnamese stainless steel easily from MRS SteelVietnam ranked 12th in the world in steel output with 19 million tons in 2023.

MRS 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,...MRS 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.

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.

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 MRS Steel via Email: vanloc@mrssteel.com.vn or Hotline: +842836223358 for the most thoughtful support!
