with the properties of high hardness, high temperature resistance, high abrasion resistance, etc., tungsten carbide has been widely used in all kinds of knives, tools, but the density of tungsten carbide is small and it is considered as brittle material.So its application is limited.Based on chromium molybdenum steel, high carbon martensitic stainless steel, high-speed steel matrix phase made of steel bonded carbide TiC, WC, hard, this alloy has both the advantages of steel and carbide.
