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