PROPRIETARY BÖHLER W320 Heat Treatments

Annealing: 750 to 800°C / Controlled slow cooling in furnace (10 to 20°C/h) to approx. 600°C air cooling.
Stress relieving: 600 to 650°C, slow cooling in furnace. 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: 1010 to 1050°C, oil, salt bath (500 to 550°C), air. Holding time after temperature equalization: 15 to 30 minutes.
Tempering: Slow heating to tempering temperature immediately after hardening/time in furnace: 1 hour for every 20 mm of work piece thickness, but not less than 2 hours/ air cooling (minimum holding time: 1 hour);
1^st tempering approx. 30°C above maximum secondary hardness
2^nd tempering to desired working hardness
3^rd tempering for stress relieving. 30 - 50°C below highest tempering temperature
