PROPRIETARY BÖHLER K190 Microclean Heat Treatments
- Annealing: 800-850°C (1472-1562°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: 650-700°C (1202-1292°F) After through-heating, soak for 1 to 2 hours in neutral atmosphere. Slow cooling in furnace.
Hardening and tempering: 1050-1150°C (1922-2102°F); Vacuum hardening is recommended. Alternative: quenching from a neutral atmosphere in oil, salt bath 220 to 250°C or 500 to 550°C (428 to 482°F or 932 to 1022°F), gas, air. A sufficiently high cooling rate must be ensured. Holding time after temperature equalization: 20 to 30 minutes. Soaking time depends on the size of the workpiece and furnace parameters. We recommend hardening from the lower end of the hardening temperature range when high toughness is required and/or when the tool is of complex shape. If high wear resistance is of the utmost importance, we recommend hardening from the top end of the hardening temperature range. After hardening, tempering to the desired working hardness according to the tempering chart.
