Description
Chrome Carbide Overlay Wear Plate is made of Q235 steel plate as the substrate, and then chromium carbide is fused on the surface of the substrate by open arc welding, which is perfectly combined with the surface of the substrate to form a wear-resistant protective layer. The wear layer of chromium carbide wear-resisting plate is mainly chromium alloy, and manganese, molybdenum, niobium, nickel and other alloy components are also added. The carbide in the metallographic structure is distributed like fiber, and the direction of fiber is perpendicular to the surface. The microhardness of carbide can reach HV1700-2000 and the surface hardness can reach HRc58-62. Alloy carbide has a strong stability at high temperature, maintain high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.
