4CrW2Si Hardware Tool Steel Bar

 

4CrW2Si impact tool steel, 4CrW2Si can do cold work die steel, but also do hot work die steel. 4CrW2Si alloy tool steel is based on the chrome silicon steel by adding 2.00% ~ 2.50% (mass fraction) of tungsten and thus have a certain hardenability and high temperature strength, while in the tempering state may obtain higher toughness . Mainly used in the production of high impact load operating tools, such as pneumatic tools, prickly heat, trimming punching composite die, die, cold cut with scissors and other punching tools, and some small hot die.

 

4CrW2Si steel is based on the chrome silicon steel by adding a certain amount of tungsten and the formation of the steel, due to the addition of tungsten and help to save during the quenching of relatively fine grain, it is possible to get tempering more High toughness. 4CrW2Si steel also has a certain degree of hardenability and high temperature strength. The steel used to make high impact load operating tools, such as pneumatic tools, blanking trimming composite die, die, cold cut with scissors and other punching tools, as well as some small hot die.
