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
