Vanadium iron is through the reduction of vanadium and titanium alloy iron and the content of vanadium, Vanadium content no less than 35.0% presented (weight) and not more than 85.0% 85.0% (weight). Vanadium iron steel industry is an important alloy additive. Vanadium can enhance the strength of steel, heat-resistant, ductility and toughness. Since the 1960s, ferrovanadium industrial application in steel increased dramatically, 1988 has accounted for 85% of vanadium consumption. In the aspect of vanadium steel consumption ratio for carbon steel 20%, high strength steel low alloy steel 25% ,alloy steel 20%, tools steel 15%. Containing vanadium high-strength low-alloy contents steels (HSLa) with its strength and is widely used in oil/gas pipelines, buildings, Bridges, rail, pressure vessels, aircraft, etc. At present various containing vanadium steel used more widely.Vanadium iron is composed of vanadium and iron, mainly in steelmaking ferroalloy as high vanadium alloy additive, also used for non-ferrous alloy iron vanadium additives. Common vanadium iron containing vanadium such as 80% 40% and 60% .
