M42 Tool Steel Hardening
M42 steel has 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. If not available, pack hardening in spent pitch coke is suggested. The temperature employed is usually 1800°-1850°F, depending on size section.
Quenching of HSS M42 Steel Material
- Quenching temperature (salt bath furnace): 1177℃
- Quenching temperature (controlled atmosphere furnace): 1188℃
- Heat preservation time: 5-15 minutes
- Quenching medium: air cooling
Tempering of HSS M42 Tool Steel
- Tempering temperature: 538℃
- After tempering hardness HRC or higher: 66
