6CrW2Si chrome silicon steel is based on adding a certain amount of tungsten and the formation of the steel, as quenched tungsten help save more fine grain, leaving the state to obtain a higher tempering toughness. 6CrW2Si than 4CrW2Si steel and steel with a higher quenching 5CrW2Si hardness of steel and some high-temperature strength. 


 To withstand impact loads used for the manufacture of high wear resistance but requires tools such as pneumatic tools, chisels and punch Bureau mold, cold shear blades, punch with the die side, pneumatic hammers and other tools.
