Properties:
Tungsten, also known as wolfram, is a chemical element with
the chemical symbol W and atomic number 74.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.
