W6Mo5Cr4V2(M2) hot rolled steel round bars

W6Mo5Cr4V2(M2) hot rolled steel round bars

M2 is a molybdenum high-speed steel, which has the advantages of small carbide non-uniformity and high toughness. It is easy to overheat, so the quenching temperature should be strictly controlled, and the protection requirements for heat treatment should be strict

SAE M2 Tool Steel Material Mechanical Properties

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

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

Forged of M2 HSS Steel metal 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 SAE M2 Steel

M2 HSS Steel Annealing

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.

M2 tool Steel Hardening

M2 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.
