The alloy wear resistant layer and matrix of NM400 wear resistant steel plates are metallurgical bonding. The high hardness self-shielding alloy welding wire is welded evenly on the substrate by special equipment and automatic welding technology. The composite layer is one to two or even multi-layer. The uniform transverse cracks appear in the composite process because of the different alloy shrinkage ratio. This is the remarkable characteristic of NM400 wear resistant steel plates.
NM400 wear resistant steel plate has high wear resistance and good impact performance. NM400 steel can be cut, bend, weld and so on, and can be connected with other structures by welding, plug welding, bolt connection and other ways. With time-saving, convenient and other characteristics in the process of maintenance, NM400 wear resistant steel plates are widely used in metallurgy, coal, cement, electricity, glass. Mining, building materials, bricks and tiles and other industries. Compared with other materials, NM400 steel has a high cost performance ratio, and has got more and more industries and manufacturers favor.
