about wear resistant steel NM400
    
    NM400 wear-resistant steel plate is a kind of heat-treated constructional wear-resistant steel with high wear resistance and good impact performance. It can be cut, bending, welding and so on. The equipment and parts that need to resist wear and bear certain impact load mainly use NM400 steel plate.
    
    NM400 steel plate has good cutting performance, bending performance, surface performance, heat treatment performance. Through quenching and tempering, the tensile strength can be increased by more than 1250 MPa, the average Brinell hardness is 400, and the surface can produce a protective film with a good adhesion. With the increase of hardness, its wear resistance is greatly improved and its impact resistance is also greatly improved.
    
    In order to improve the wear resistance of NM400 steel plate, we add alloy elements such as Cr, Mo and so on in the smelting process, change some process parameters, do double vacuum smelting, double normalizing and tempering, and the surface is sprayed with high wear-resistant alloy. As a result, the NM400 steel plate has higher wear resistance, making it especially suitable for applications that require high wear resistance and impact strength such as excavator buckets, crusher blades and other structural parts.
    
    Furthermore, the NM400 steel plate can also be used in atmospheric corrosion-resistant special structural parts, such as marine containers, bridges, chimneys, vessels, vehicles and so on. In addition, the NM400 steel plate can also be used as a heat-resistant container wall, can withstand a temperature of 500 ℃, but the heat treatment must be careful and not exceed the temperature of 430
    
    Therefore, the NM400 steel plate has good wear resistance and impact resistance, which is an ideal material for structural parts with high wear resistance and impact strength, such as excavator buckets, crusher blades and other structural parts. It is also suitable for atmospheric corrosion-resistant special structural parts and heat-resisting container wall.
