Mechanical Properties of W6Mo5Cr4V2 Steel

Hardness, Rockwell C (tempered at 621°C, quenched at 1204°C): 62 HRC.

Hardness, Rockwell C (quenched at 1204°C) ): 65 HRC

Forged of W6Mo5Cr4V2 Steel Material

At first, Pre-Heating to 650-750℃,Then heat to forged temperature. Soak at 1204°C, ensure heat thorough. Then start forged, the forged temperature no low than 950℃. After forging, cool slowly.

Heat Treatment of W6Mo5Cr4V2 Steel


At first, Slowly heat to 871℃,then slowly Cool to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 255 Max.


W6Mo5Cr4V2 steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested.

Features and Application:

W6Mo5Cr4V2 Steel is molybdenum series high speed steel, have the advantages of small carbide inhomogeneity and high toughness. Moreover, it is easy to overheating, should strictly control the quenching heating temperature, the more strict protection for heat treatment. Because of its hardness and wearability, used in the manufacture of cutting more difficult to cutting tool materials.

W6Mo5Cr4V2 Steel high speed steel with carbide orientation is bigger, so the more strict protection for heat treatment, is suitable for the mould vibration and shock loads.  Application as Cold forging die, precision die, pressure molding powder, etc., cutting tools, adding glass fiber plastic mould etc. So it is suitable for the mould vibration and impact loads, deep drawing mould, punching die. Metal cutting saw blade, cold heading and extrusion.
