Vanadium

CAS number : 7440-62-2

Molecular weight :50.94

Molecular formula/chemical symbol :V

Description :

Silver metal, body centered cubic crystal, high melting point, often with niobium, tantalum, tungsten, molybdenum and difficult melting metal. Have ductility, qualitative hard, no magnetic. With high hydrochloric acid and sulfuric acid ability, and in the resistance to gas - salt - water corrosion performance than most of the stainless steel is good. In the air will not be oxidation, soluble in hydrofluoric acid, nitric acid and aqua regia

USES :
The use of vanadium is very widely, having metal "vitamin," said. The original vanadium steel most applications, through the refining steel organization and grain, and improve the grain coarsening temperature, thus creating a increase steel strength, toughness and wear resistance. Later, people gradually and found the vanadium titanium alloy in the outstanding improvement action, and applied it to the aerospace field, in order to make the aerospace industry has made breakthrough progress. Mainly used in the manufacture of high speed cutting steel and other steel and catalyst. The vanadium blending into steel, can be made into vanadium steel. Vanadium steel than ordinary steel structure more closely, toughness, elastic and higher mechanical strength. Vanadium steel armour piercing shell, can shoot through and cm thick steel plate. But, in the iron and steel industry, and is not the pure metal vanadium added to iron and steel made vanadium steel, but directly used vanadium iron ore refined into vanadium steel.
