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. See the data bellow.
Tempering Temperature | Hardness(HRC) |
100oC | 66 |
200oC | 65 |
300oC | 59 |
400oC | 53 |
