Main components of alloy wear-resistant layer

Mainly made of chromium alloy, with the addition of other alloy components such as manganese, molybdenum, niobium, nickel, etc. The carbide in the metallographic structure is distributed in a fibrous shape, with the fiber direction perpendicular to the surface. The micro hardness of carbides can reach above HV1700-2000, and the surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good oxidation resistance, making them fully functional within 500 ℃.
The manifestations of the wear-resistant layer include narrow channels (2.5-3.5mm), wide channels (8-12mm), curves (S, W), etc; Mainly made of chromium alloy, with the addition of other alloy components such as manganese, molybdenum, niobium, nickel, boron, etc. The carbide in the metallographic structure is distributed in a fibrous form, with the fiber direction perpendicular to the surface. The carbide content is 40-60%, and the micro hardness can reach HV1700 or above, while the surface hardness can reach HRC58-62.
