High-carbon and high-vanadium powder high-speed steel contains a lot of W, Mo, Cr, V and other elements. The alloy carbide formed with carbon improves the properties of the steel. Because of the uniqueness of smelting high speed steel, the content of alloy elements is higher. Especially high V and high Co steels are widely used. Powder high speed steels have higher hardness, red hardness, wear resistance and toughness.
