Mainly used for smelting alloy steel. About 90% of the vanadium consumed in the world is used in the steel industry. In ordinary low alloy steels, vanadium mainly refines grain size, increases steel strength and inhibits its aging effect. In the alloy structure steel is to refine the grain, increase the strength and toughness of the steel; Used in conjunction with chromium or manganese in spring steel to increase the elastic limit of steel and improve its quality; In tool steels, it mainly refines the structure and grain, increases the tempering stability, enhances the secondary hardening, improves the wear resistance, and prolongs the service life of tools. Vanadium also plays a beneficial role in heat - and hydrogen-resistant steels. Vanadium added in cast iron, due to the formation of carbides and promote the formation of pearlite, the cementite stability, the shape of graphite particles fine and uniform, refining the matrix grain, so that the casting hardness, tensile strength and wear resistance to improve.
