The Wear-Resistant Layer of Hardox 400 Plate

The commonly used Hardox 400 plate is made of common low-carbon steel or low-alloy steel with good toughness and plasticity by surfacing a certain thickness of alloy wear-resistant layer with high hardness and good wear resistance.

The wear-resistant layer of Hardox 400 plate is mainly chromium alloy, and other alloys such as manganese, molybdenum, niobium and nickel are added. The carbides in the metallographic structure are fibrous and the direction of the fibers is perpendicular to the surface. The microhardness of carbides can reach over HV1700-2000 and the surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperature, maintain high hardness, and have good antioxidant properties. They can be used normally within 500℃.
