wear carbide steel plate and the substrate is metallurgical bond. Through special equipment, using automatic welding process, the high hardness self-protection alloy wire welded evenly on the substrate, the composite layers from one to two or even more layers, the composite process due to different alloy shrinkage ratio, uniform transverse cracks occur, which Is a significant feature of wear-resistant steel.
wear carbide steel plate mainly chromium alloy, but also added manganese, molybdenum, niobium, nickel and other alloy components, carbide distribution in the fibrous structure, fiber orientation perpendicular to the surface. Carbide microhardness can reach more than HV1700-2000, the surface hardness can reach HRC58-62. Alloy carbide has high stability at high temperature to maintain a high hardness, but also has good oxidation resistance, completely normal within 500 ℃.
