PROPRIETARY SIHARD 3501 Heat Treatments

  • Soft annealing: Heat to 730-760°C, 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. 600-650°C, 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 780-810°C, 820-850°C followed by water or oil quenching. Hardness after quenching is about 60 HRC.
    Tempering temperature: 150-180°C.
