Composite wear-resistant steel plate, the chemical composition of the alloy wear-resistant layer has a carbon content of 4 to 5%, and the chromium content is divided into two levels: 18 to 30% and 30 to 40%. The volume fraction of Cr7C3 carbide in its metallographic structure Reaching more than 50%, the macro hardness is HRC56~62, and the hardness of chromium carbide is HV1400~1800. Since carbides are distributed vertically in the direction of wear, even compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.
