What is en NM400 steel equivalent astm material

    
    NM400 steel is a wear-resistant steel, which is a type of high-strength steel alloy and has excellent wear resistance properties. It offers better mechanical properties than ordinary steel, such as excellent toughness, high resistance to abrasion, good dimensional accuracy and better weldability. Its hardness level is between 370 and 430, which offers very good wear resistance properties and is ideal for applications where frequent impacts of medium intensity are expected.
    
    NM400 steel is equivalent to ASTM A128, a type of manganese alloy steel. ASTM A128 grade B2 is a wear-resistant steel, which means that it provides excellent resistance to abrasive wear. The A128 grade B2 is a heat treated and quenched medium carbon steel, which offers a higher hardness than the standard AISI and SAE grades. This medium carbon steel offers very good resistance to abrasion, impacts, and shocks and is used for applications where a higher degree of wear is expected.
    
    NM400 steel and ASTM A128 grade B2 are used extensively in industries such as mining, construction, and heavy machinery. Due to its high wear-resistance and good mechanical properties, it is also used to manufacture armour plating and parts for military vehicles, cutting edges of blades, armor plates on construction machines, and even wear-resistant components used in industrial parts.
    
    NM400 steel and ASTM A128 grade B2 have a good formability when compared to other wear-resistant steels, making them suitable for many fabrication processes, such as cutting, bending, drilling, welding, and machining. By utilizing its high strength, NM400 steel and ASTM A128 grade B2 can achieve lighter and thinner components and thus design freedom is achieved.
    
    Since NM400 steel and ASTM A128 grade B2 are designed for abrasive wear conditions, they offer protection against corrosion in adverse environments. This provides improved performance in environments where corrosion and abrasion are agent factors and where they may cause premature failure of the components.
    
    Overall, NM400 steel and ASTM A128 grade B2 are excellent wear-resistant steels that offer superior mechanical properties, good formability and excellent corrosion resistance. These steels are commonly used in applications that require wear resistance, like mining industries, construction industries and military vehicles.
