1.Wear-resisting Steel Plate is composed of low Carbon Steel Plate and alloy wear-resisting layer. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity of resisting external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.
2.Wear-resisting steel alloy wear-resisting layer and base plate are metallurgical combination. By means of special equipment and automatic welding process, the high-hardness self-protecting alloy wire is uniformly welded on the substrate, and the composite layers are one to two or even more. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.
3.The wear resistant layer of the alloy is mainly chromium alloy, while manganese, molybdenum, niobium, nickel and other alloys are added. The microhardness of carbide can reach above hv1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy has a strong stability at high temperature, maintain a high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.
4.The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly composed of chromium alloy, while manganese, molybdenum, niobium, nickel, boron and other alloy components are added. With 40-60% carbide content, the microhardness can reach above HV1700 and the surface hardness can reach hrc58-62.
