Heat treatment Related
- Annealing of 100MNCRW4 Tool steel
Slowly heated to 740-770 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The 100MnCrW4 tool steel will get MAX 250 HB （Brinell hardness）.
- Hardening of 100MnCrW4 tool steel
100MNCRW4 steels should be heated uniformly to 780-820°C (1436-1508°F) until completely heated through. If needed, the steels can be preheated at 300-500°C (572-932°F). About 30 min per 25 mm of ruling section is to be provided and then the steels should be immediately quenched in oil.
- Tempering of 100MnCrW4 tool steel
Tempering of 100MNCRW4 steels is performed at 100-250°C, Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Get Rockwell C hardness of 53 to 64.
