Application
Mainly used for smelting alloy steel. About 90% of the vanadium consumed in the world is used in the steel industry. Vanadium in
ordinary low alloy steels mainly refines grains, increases the strength of steel and inhibits its ageing effect; in alloy
structural steels, it refines grains and increases the strength and toughness of steel; in spring steel, it combines with chromium
or manganese. With the use, increase the elastic limit of steel and improve its quality; In the tool steel, the main refinement of
the steel structure and grain, increase the tempering stability of steel, enhance its secondary hardening, improve its wear
resistance, extend The service life of the tool; vanadium also plays a beneficial role in heat-resistant steel and
hydrogen-resistant steel; vanadium added in cast iron promotes the formation of pearlite due to the formation of carbides,
stabilizes the cementite, and the shape of graphite particles is fine. Uniformly refines the crystal grains of the matrix, thereby
increasing the hardness, tensile strength, and wear resistance of the casting.
