Wear-resistant steel plate alloy wear-resistant layer and matrix are metallurgical combination. Through special equipment, automatic welding technology is adopted to weld the high hardness self-protective alloy wire into the substrate. The composite layer is several layers to two or more layers, and the uniform transverse cracks occur due to the contraction ratio of the alloy in the composite process, which is a remarkable characteristic of the wear-resistant steel plate.
The wear-resistant layer is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in metallographic tissue is fibrous and the fiber direction is perpendicular to the surface. The microhardness of carbide can reach above HV1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy at high temperature has a strong stability, high hardness, but also has the very good oxidation resistance, completely normal use within 500 ℃.
