Vanadium steel

Vanadium steel is a type of steel alloy that contains vanadium as one of its alloying elements. Vanadium is added to steel to improve strength, toughness, and corrosion resistance. Vanadium steel is commonly used in a wide range of applications, including high-stress applications such as aircraft components, power generation turbines, and armor plating.

The addition of vanadium to steel results in a more uniform grain structure and increased hardenability, which contributes to the increased strength and toughness of the steel. The corrosion resistance of vanadium steel is also improved due to the formation of a vanadium oxide layer on the surface of the steel that acts as a barrier to the entry of corrosive substances.

Overall, the use of vanadium steel provides significant benefits in terms of improved mechanical properties and resistance to corrosion, making it a popular choice for many high-performance applications.
