Forged of M42 Steel metal material
At first, Pre-Heating to 650-750℃，Then heat to forged temperature. Next, Soak at 1050-1100 °C , ensure heat thorough. Then start forged, the forged temperature no low than 950℃. After forging, cool slowly .
Heat Treatment of SAE M42 Steel
- M42 HSS Steel Annealing
Firstly, Slowly heat to 870℃，then slowly Cool to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 269 Max
- M42 tool Steel Hardening
M42 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. Finally, the temperature employed is usually 1800°-1850°F, depending on size section.
- Quenching of HSS M42 Steel material
Quenching temperature / ℃ | salt bath furnace: 1177
