Vanadium is a strategic metal primarily used as a strengthening alloy to steel and titanium. Small amounts of Vanadium, added to steel makes it stronger, tougher and lighter.
Vanadium in its pure form is a soft, grey, ductile element primarily derived from mined iron ore and steel slag. A small amount of Vanadium (typically 0.04 – 4% in steel compositioni) forms carbides in steel and promotes fine grain size, a process which imparts hardness, wear resistance, seismic resistance and increased strength to the steel.
Vanadium has the strongest strength to weight ratio of any alloy. It is the most commonly used alloy for strengthening steels and is used primarily in the construction, infrastructure and transportation industries. Its anti-corrosive properties also make it ideal for use in industrial applications like chemical and power generation plants as well as in oil refineries. Also when alloyed with titanium and aluminum, small amounts of Vanadium help form very strong, lightweight engineering materials which are ideal for use in the aerospace and aviation industries.ii
