Mainly used for smelting alloy steel. About 90% of the vanadium consumed in the world is used in the steel industry

1. In ordinary low alloy steel, vanadium mainly refines grains, increases the strength of steel and inhibits its aging effect;

2. in alloy structural steel, it refines grains, increases the strength and toughness of steel;

3. in spring steel, it is combined with chromium or manganese Use together to increase the elastic limit of steel and improve its quality;

4. in tool steel, it mainly refines the structure and grain of steel, increases the tempering stability of steel, enhances its secondary hardening effect, improves its wear resistance, and prolongs The service life of tools;

5. in heat-resistant steel and hydrogen-resistant steel, vanadium also plays a beneficial role;

6. vanadium added to cast iron promotes the formation of pearlite due to the formation of carbides, stabilizes cementite, and the shape of graphite particles is fine and Uniform and refine the grains of the matrix, thus improving the hardness, tensile strength and wear resistance of the casting
