- Soft Annealing: Heat to 680-720oC, cool slowly. This will produce a maximum Brinell hardness of 248.
- Nitriding:
Gas/plasma nitriding temperature (gas, salt bath): 570-580°C
Gas/plasma nitriding temperature (powder, plasma): 580°C
Surface hardness after nitriding: 800 HVHardening: Harden from a temperature of 850-880°C followed by oil quenching.
