Steel Production and Vanadium Benefits

Steel Production and Vanadium

Steel Production and Vanadium

The steel industry, as one of the higher carbon emitting industries, is decreacing crude steel production on order to realize high quality development.

The addition of vanadium to steel strengthens the bar and contributes to the high quality development of the steel industry. Vanadium containing steel bars can help the industry to reduce carbon production and energy consumption.

Vanadium is a high melting point rare metal, silver gray, in the form of iron vanadium, vanadium compound and metal vanadium widely used in metallurgy, aerospace, chemical and battery industries.  At present, the vanadium   is added to steel in the form of iron vanadium and vanadium nitride. The largest consumption is high strength low alloy steel (25%), carbon steel (20%), alloy steel (20%) and tool steel (15%).Vanadium in the main role is to refine the grain, so as to enhance the strength of steel, quenchability, weldability and wear resistance.

The accession of vanadium has shown a great effect on improvement of coordination between strength and ductility, sensitivity to strain aging and high strain and low cycle fatigue property. The use of (vanadium) micro-alloying to increase the strength of steel bars from 400MPa to 500MPa can theoretically save 15% to 20% of steel consumption. At the same time, according to China’s steel industry energy structure and average energy consumption is measured, can reduce carbon dioxide emissions up to 370 million tons / year or more.
