Ferro Tungsten
- Properties: tungsten is one of the important alloy elementswhich are used to make special steel. While tungsten reduce alittle elongation rate of steel, it raises strength limit and yieldpoint and also raises hardness and abrasion resistance of steel. Itis very important that tungsten has good influence on hightemperature mechanical properties of steel to improve heatresistance and tempering stability of steel.
