4CrW2Si round

4CrW2Si steel is steel adding a certain amount of tungsten in the chromium-silicon steel on the basis of the formation, due to the addition of tungsten and helps save during quenching relatively fine grains, it is possible to obtain more in a tempered condition high toughness. 4CrW2Si steel also has a certain hardenability and high temperature strength. Tools of the steel used for the manufacture of high impact load operations, such as pneumatic tools, chisel, composite blanking trimming die, die, cold cut with scissors punching tools, as well as some small hot die.
