Nm300 Nm400 Nm450 Nm500 Wear Resistant Steel Plate NM300
Bimetallic composite wear-resistant steel plate by low carbon steel plate and alloy wear-resistant layer of two parts, anti-wear layer one
Generally 1/3-1/2 of the total thickness. The strength, toughness and resistance to external forces are provided by the matrix
Plastic and other comprehensive properties, by the wear layer to provide wear resistance to meet the requirements of the specified working conditions.
The wear-resistant layer and the substrate of wear-resistant steel plate alloy are metallurgical bonding. Through special equipment, adopt
Automatic welding process, the high hardness self-protection alloy welding wire uniformly welded on the substrate
The number of composite layers is one layer to two layers or even multiple layers, and the composite process is different due to the shrinkage ratio of the alloy
Now uniform transverse crack, which is a significant feature of wear-resistant steel plate.
The wear layer is mainly made of chromium alloy, and other alloys such as manganese, molybdenum, niobium and nickel are also added
The carbides in the metallographic structure are distributed like fibers, and the direction of fibers is perpendicular to the surface. carbide
The microhardness can reach more than HV1700-2000, and the surface hardness can reach HRc58-62
. Alloy carbides have strong stability at high temperatures and maintain a high hardness at 500℃
It can be used normally.
