NM450 material equivalent

    
    NM450 material is a special heat-treated high-hardness abrasion-resistant steel plate, produced by quenching and tempering process. Its chemical composition is as follows: C: 0.31~0.40, Si: 0.10~0.35, Mn: 1.60~2.00, P<0.015, S<0.018, Cr: 1.50~2.50, Ni: 0.7 and Mo: 0.2~0.5. NM450 material has good mechanical properties with yield strength 4 times greater than that of carbon steel, and its hardness and impact toughness can be improved further. Under impact load, NM450 material can absorb energy which is equivalent to 2-3 times that of carbon steel.
    
    NM450 material can be used for different applications. It can be used for producing safety facilities and components for coal mining machinery and other mining machinery, cement mill, power plant equipment, hoisting equipment and other construction machinery. It is also suitable for loaders, bulldozers, excavators and other wear-resistant equipment.
    
    The equivalent of NM450 material includes the ASTM A128 grade B2, ASTM A131 grade A, ASTM A514 grade F and UNS K11820. ASTM A128 grade B2 is an austenitic manganese steel with a minimum yield strength equivalent to NM450 material. ASTM A131 grade A is a normalized and tempered heat-treated steel plate with a minimum tensile strength equivalent to that of NM450 material. ASTM A514 grade F is a high-strength, quenched and tempered heat-treatable steel plate with a yield strength of at least 100,000 psi (690 MPa) and ultimate tensile strength of 110,000 psi (760 MPa). UNS K11820 is a wear-resistant steel alloy designed for improved wear-resistance for wear applications. It is composed of iron, chromium and boron and has a minimum hardness of 420 HBW.
    
    In summary, NM450 material is a special heat-treated high-hardness abrasion-resistant steel plate with excellent mechanical properties. Its equivalents include ASTM A128 grade B2, ASTM A131 grade A, ASTM A514 grade F and UNS K11820. NM450 material has a wide range of important industrial applications and can be used for producing safety components and wear-resistant equipment in various industries.
