85% of vanadium in the world is mainly used as steel additives to improve the strength, toughness and heat resistance of steel. Vanadium is a universal alloy additive. Adding a small amount of vanadium (a few percent and a few thousandths) to steel can It can produce high-strength low-alloy steel (0.04%-0.15% V), high-speed steel (1%-3% V), tool steel, stainless steel (2%-14% V) and permanent magnets.

The main function of vanadium in steel is: vanadium works with carbon and nitrogen in steel to form small and hard refractory metal carbides and nitrides. These compounds act as refiners and precipitation strengthening agents, which can increase the strength of steel. strength, toughness and wear resistance. Vanadium is used in tool and die steel. In high carbon steel, vanadium forms hard carbides to achieve the wear resistance required by dies and machine tools. At high temperatures, the carbides do not soften, so that the cutting edge at the end of a high-speed tool does not deteriorate when it is red hot. Bearings for gas turbine engines require the same properties and use this steel. Vanadium-containing steel has high strength, toughness, wear resistance, and good corrosion resistance. It is widely used in oil/gas pipelines, machine manufacturing, construction, automobiles, railways, pressure vessels, bridges, metal molds and other departments.
