6 100Cr2 HEAT TREATMENT:
- FORGING:</emHot forming temperature: 1100-850oC.
- SOFT ANNEALING: Heat to 730-760oC, cool slowly. This will produce a maximum Brinell hardness of 207.
- STRESS RELIEVING: Stress relieving to remove machining stresses should be carried out by heating to approx. 600-650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
- HARDENING: Harden from a temperature of 780-810oC, 820-850oC followed by water or oil quenching. Hardness after quenching is about 60 HRC.
- TEMPERING: Tempering temperature: 150-180 oC.
