Drill bits enhanced with vanadium. These bits are made of an alloy of steel and vanadium. Vanadium has a high resistance to corrosion. Steel, itself an alloy of iron and carbon, is alloyed with vanadium to produce ferrovanadium - a material with greater strength and rust resistance than steel alone. About 80% of the world's vanadium production is used in this way.
