6.HEAT TREATMENT:
- NORMALIZING: Normalizing temperature: 860-900oC.
- SOFT ANNEALING: Heat to 760-800oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 217.
- 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 830-890oC followed by oil quenching. Hardness after quenching is approx. 64 HRC.
- TEMPERING: Tempering temperature: 150-180oC.
7.Mill′s test certificate:
EN 10204/3.1 with all relevant data reg. chem. composition, mech. properties and results of testing.
