NM400 Grade equivalent

    
    NM400 steel is a wear-resistant steel plate with a hardness of 400 HBW (Brinell hardness number) with a yield strength of more than 2300 MPa and abrasion performance reaching 4-5 times the original low alloy steel. NM400 has features such as high strength, abrasion resistance, impact resistance, non-temperature sensitivity, etc. It is widely used as wear-resistant inner layer materials in industry and has gained a good reputation.
    
    NM400 belongs to high-strength wear-resistant steel plate, which is widely used in engineering machinery, ports, pesticides, river transport, and the pavement of mines by the characteristics of high wear resistance and impact resistance and good weldability. It has the characteristics of high strength, high toughness, and good plasticity, which can be applied to various harsh environment conditions, such as abrasion, and wear. Structural parts.
    
    Compared to the conventional low-alloy steel, the yield strength of NM400 can reach 2434MPa, and its impact toughness can reach 31J/cm2. The hardness of the wear-resistant layer is HRC58-62, which is more than 3-5 times than the common low-alloy steel. NM400 also has good corrosion resistance, cold and heat resistance and good flatness, and its hardness can be up to 500HB compared to ordinary steel, forming a high-strength wear-resistant surface layer.
    
    Therefore, compared with ordinary low-alloy steel, NM400 is more resistant to wear. NM400 has an equivalent hardness of about 750HBW. This high hardness can meet the demands of most wear-resistant applications, and it can resist wear, deformation and crack, which proves its excellent performance.
    
    NM400 has abrasion resistance that is comparable to a variety of wear-resistant materials such as Mn13 and various types of hard wear-resistant alloy steel, but its physical performance is much better than any of them. In concrete mixing, NP400 can perform a better mixing experience performance, which is superior to alloys of other materials.
    
    In addition, the weldability, plasticity and molding of NM400 are also very good. For example, after the NM400 armor plate is welded by friction welding, it has a better hardness and wear resistance. In addition, NM400 is not only a wear-resistant material but also can provide certain anti-corrosion performance.
    
    NM400 is a high-strength wear-resistant steel plate that can provide satisfactory wear-resistant performance and can meet different working environment needs. It has excellent hardness, yield strength and impact toughness, which make it one of the main wear-resistant steel for industrial applications.
