PROPRIETARY BÖHLER W360 ISOBLOC Heat Treatments

  • Annealing: 750-800°C (1382-1472°F); Holding time 6 to 8 hours. Slow, controlled cooling in furnace at a rate of 10 to 20°C/h (18 to 36°F/h) down to approx. 600°C (1112°F), further cooling in air.

    Stress relieving: 650-700°C (1202-1292°F); For stress relief after extensive machining or for complicated tools. Holding time depending on tool size after complete heating 2-6 hours in neutral atmosphere. Slow furnace cooling.

    Hardening and tempering: 1050°C (1922°F); Holding time after temperature equalization: 15 to 30 minutes; In order to prevent coarsening of the grain, hardening must be carried out at the recommended temperature; Quenching: oil, salt bath (500-550°C [930 to 1020°F]), air, inert gas in vacuum; After hardening, required tempering treatment to achieve desired working hardness.
