PROPRIETARY BÖHLER K105 Heat Treatments


  • Annealing: 800 to 850°C (1472 to 1562°F); Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (18 to 36°F/hr) down to approx. 600°C (1112°F)), further cooling in air.

    Stress relieving: 650 to 700°C (1202-1292°F); Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 to 2 hours.

    Hardening and tempering: 980 to 1010°C (1796-1850°F); Oil, salt bath from 220 to 250°C or 500 to 550°C (428 to 482°F or 932 to 1022°F), air, gas. Tools of intricate shape or with sharp edges should preferably be hardened in air or salt bath. Holding time after temperature equalization: 15 to 30 minutes. After hardening, tempering to the desired working hardness, see tempering chart.
