Description
Wear-resistant layer 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 ℃.
