Fuji medium grain tungsten steel carbide steel G70 Hardness: 85 Bending force: 2940 Extension Zhang: 1620 Compression strength: 3530 Shock level: 74 Uses: There are good toughness and resistance to shear failure strength for forging dies. Tungsten / carbide there is one is one or more carbides (such as TiC, WC, etc.) for the hardening phase in alloy steel (such as high-speed steel, molybdenum chrome steel, etc.) Yong Chao powder binder system Cheng, called steel carbide. Its hardness is between between steel and carbide, but the toughness and can greatly improve the machining and heat treatment processing. The typical hardness of steel Carbide: After quenching - tempering hardness 69 ~ 73HRC, high-speed steel 65%.
