Continuous Cooling Transformation (CCT) Diagram
Soft Annealing
Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 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 760-820oC, 800-840oC followed by water or oil quenching. Hardness after quenching is 64-66 HRC.
Tempering
Tempering temperature: 150-250oC.
Tempering Temperature (oC) vs. Hardness (HRC)
100oC | 200oC | 300oC | 400oC |
66 | 65 | 59 | 53 |
Forging
Hot forming temperature: 1050-850oC.
