Ferrotungsten

Used in:
Ferrotungsten is used as an additive in steelmaking and casting. It is one of the most important alloying elements in the production of special steels. Tungsten can improve the strength limit and yield point, hardness and wear resistance of steel. The most importance is that tungsten has a good effect on the high temperature mechanical properties of steel, it can improve the heat resistance and temper stability.
