Vadandium

Vanadium is a frequently occurring element and is found in many minerals and ores. This heavy metal is mainly used in the steel industry, because as an alloying element it has a positive influence on most material properties of steel.

Vanadinite | Vanadium mineral

In the steel structure, vanadium forms together with carbon vanadium carbide, which increases strength, wear resistance and ductility. The addition of vanadium supports the formation of small grains in the microstructure, making these steels very easy to weld.

The influence of vanadium on the mechanical properties of steel:

Scaling Decrease - 1
Machinability no bearing 0

Trivia

Vanadium was discovered twice. First the Spanish mineralogist Andrés Manuel del Rio discovered it in Mexico in 1801. He named the new element "Panchrome" and later "Erythronium". Unfortunately, his discovery fell into oblivion because he was convinced by a chemist that it would only be contaminated chromium.

30 years later, vanadium was rediscovered by Nils Gabriel Selfstöm, who named the element "Freyja" after the Nordic goddess of beauty because of its variety of colours. In old traditions from Iceland, Freyja is nicknamed Vanadis.
