Vanadium

A silvery metal that resists corrosion. About 80% of the vanadium produced is used as a steel additive. 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.

The Rocks at the Top of the World | Science History Institute

The rapid increase in vanadium production caused the price to collapse to the point where mine operations were shut down between 1912 and 1913 and again in 1922. Before ore was first dug out of Minas Ragra, vanadium had sold for $4,000 per pound. Soon after the mine closed for the first time, vanadium was selling for only $1.80 per …
