PROPRIETARY SITHERM 2888 Heat Treatments

  • Soft Annealing: Heat to 760 - 840°C, cool slowly in furnace. Time is 4-6 hours. Stress Relieving: should be carried out by heating to 600 - 650°C, holding for 1-2 hours at heat, followed by air cooling. Hardening: Harden from a temperature of 1100 - 1150°C followed by air, oil quenching or vacuum quenching. Tempering: 600 - 750°C, to increase hardness, temper 2 or 3 times.
