Vanadium in high speed steels

Vanadium in high speed steels Correct Answer Forms very hard carbides and thus increases wear resistance

The effects of Vanadium refines grain size, increases hardenability, fracture toughness, and resistance to shock loading. Softening at high temperatures, fatigue stress and wear resistance are improved. At greater than 0.05%, there may be a tendency for the steel to become embrittled during thermal stress relief treatments.
Vanadium is used in nitriding, heat resisting, tool and spring steels together with other alloying elements.
