PROPRIETARY SIHARD S470 Heat Treatments

  • Soft annealing: Heat to 840-860°C, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.
    Stress relieving: Stress relieving to remove machining stresses should be carried out by heating to 650°C, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
    Hardening: Harden from a temperature of 1050-1100°C followed by oil quenching. Hardness after quenching is 62-64 HRC.
    Tempering temperature: 520°C.
