ferro tungsten

1. Properties: tungsten is one of the important alloy elements which are used to makespecial steel. While tungsten reduce a little elongation rate of steel, it raises strengthlimit and yield point and raises hardness and abrasion resistance of steel. It is very important that tungsten has good influence on high temperature mechanical propertiesofsteel to improve heat resistance and tempering stability of steel.

2. Chemical Composition, Below is the specification of ferro tungsten
