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.
