NM400 steel density kg/m3 material quenching

    NM400 steel is a popular alloy steel used in a variety of applications, including construction and marine. It is created by combining elements of nickel, chromium and manganese with iron at high temperatures and pressure. This forms a tough and durable material that has a high strength-to-weight ratio and high wear resistance. It is also resistant to corrosion and abrasion, making it a popular choice for a variety of structural applications.
    
    The density of NM400 steel is 7.85 g/cm3. This is higher than standard carbon steel, which has a density of 7.87 g/cm3. However, the NM400 steel is not as dense as stainless steel, which has a density of 8.03 g/cm3.
    
    NM400 steel is traditionally used at elevated temperatures where other grades of steel may become softer and lose their strength. To improve its heat resistance and hardness, the steel is often heat treated through quenching and tempering processes.
    
    The quenching process involves heating the material rapidly to a temperature beyond its critical point. The steel is then quickly cooled to room temperature. Quenching increases the hardness and strength of the steel but also decreases its ductility. Tempering then follows, which is a process used to improve the metal's toughness.
    
     NM400 steel is suitable for components used in severe abrasion and wear environments, such as earth moving equipment, agricultural machinery, bucket teeth and blades. Due to its high hardness and strength, this alloy is commonly used in construction, such as reinforced concrete beams, shotcrete pipes, concrete sleepers and other structural components.
    
    Its high resistance to corrosion and wear makes NM400 steel an excellent choice for components used in salt water or other aggressive environments, such as propeller shafts and drivetrain parts. Its corrosion resistance is comparable to stainless steel, making it a good choice for applications where stainless steel would be too expensive.
    
    NM400 steel also finds use in highly stressed parts of machines, such as crank shafts and gears. It is also often used in blades and other cutting tools.
    
    Despite its wear resistance and high strength, NM400 steel is not as strong as some other alloys, such as S7 and H13. Additionally, the quenching and tempering process increases brittleness, which can limit its applications.
    
    Overall, NM400 steel is an excellent choice for applications that require high wear resistance and strength. Its heat-treated and quenched state provides superior mechanical properties, making it an ideal choice for construction, mining, and marine-related applications.
