Vanadium | chemical element | Britannica
Vanadium metal, sheet, strip, foil, bar, wire, and tubing have found use in high-temperature service, in the chemical industry, and in bonding other metals.Because the major commercial use of vanadium is in steel and cast iron, to which it lends ductility and shock resistance, most of the vanadium produced is used with iron as ferrovanadium (about 85 percent vanadium) in making vanadium steels.

Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium alloys are used in nuclear reactors because of vanadium’s low neutron-absorbing properties.

Vanadium - Wikipedia
Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...

Vanadium is a soft and ductile, silver-grey metal. Vanadium is normally found within magnetite iron ore deposits, and is usually mined as a byproduct and not as a primary mineral. The general process of obtaining vanadium from its ores is in the form of vanadium pentoxide (V2O5) through performing a variety of processes like smelting, leaching, and roasting after which the pentoxide is reduced ...
