PROPRIETARY BÖHLER K455 Heat Treatments
- Annealing: 710-750°C (1310-1382°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°C (1202°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 1-2 hours.
Hardening and tempering: 870-900°C (1598-1652°F); Oil, Holding time after temperature equalization: 15 to 30 minutes. After hardening, tempering to the desired working hardness, see tempering chart.
