4CrW2Si

Performance: the steel is added to 2.00%~2.50% based on chromium steel (mass fraction) of tungsten into, due to the addition of tungsten and grain to save in the quenching is fine, it is possible to obtain higher in tempered condition and improve the toughness, tempering stability, the steel has a certain hardenability and high temperature strength.

Use: for the manufacture of high impact load bearing tools, pneumatic tools, such as punching cutting edge chisel,compound die, die, cold cutting tools, as well as the small hot work die etc..

The production of varieties: hot rolling, forging, cold drawn steel wire, cold drawn material.

5CrW2Si

Performance: the steel is added to 2.00%~2.50% based on chromium steel (mass fraction) of tungsten into, due to the addition of tungsten and grain helps maintain when quenching is fine, it is possible to obtain high toughness intempered condition, and improve the stability of tempering. The steel and the hardenability and mechanical properties at high temperature.

Application: used in the manufacture of cold shear metal blade, blade screw plate blade, cold punching and trimmingdie and work during the period of woodworking tools, as well as the hand or pneumatic chisel, air hammer, boiler tools, top die and punch, cutter, scissors (heavy shock) (heavy vibration), concrete breaker etc..

The production of varieties: hot rolling, forging, cold drawn steel wire, cold drawn material.

6CrW2Si

Performance: the steel is added to 2.20%~2.70% based on chromium steel (mass fraction) of tungsten and become,with 5 CrW2Si steel as due to the addition of tungsten steel caused higher toughness in tempered condition. Thesteel ratio 4CrW2Si and high temperature strength of 5 CrW2Si with quenching hardness higher and a Hun.

Use: for the manufacture of bear impact load will require higher wear resistance of tools, pneumatic tools, such as wind, cold chisel impact mould, punching shear blade, cutting edge with a concave die and the air hammer tools etc..

The production of varieties: hot rolling, forging, cold drawn steel wire, cold drawn material.
