uses of ferrovanadium

Mainly used for smelting alloy steel. About 90% of vanadium consumed in the world is used in the steel industry. In ordinary low alloy steel, vanadium mainly refines the grains, increases the strength of the steel and inhibits its aging effect; in alloy structural steels, it refines the grains and increases the strength and toughness of the steel; in spring steel, it is combined with chromium or manganese. Used in conjunction to increase the elastic limit of steel and improve its quality; in tool steel, the structure and grain of the steel are mainly refined, the tempering stability of the steel is increased, the secondary hardening effect is enhanced, the wear resistance is improved, and the The service life of the tool; in heat-resistant steel and hydrogen-resistant steel, vanadium also plays a beneficial role; the vanadium added in cast iron promotes the formation of pearlite due to the formation of carbides, so that the cementite is stable, and the shape of graphite particles is fine and thin. Uniformity, refines the crystal grains of the matrix, thereby improving the hardness, tensile strength and wear resistance of the casting.
