PROPRIETARY BÖHLER S700 Heat Treatments

Annealing: 770 to 840°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. To relieve stresses set up by extensive machining or in tools of intricate shape. After through heating, hold in neutral atmosphere for 1 to 2 hours.
Hardening: 1200 to 1240°C, oil, salt bath (500 to 550°C), vacuum.
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 and 2^nd tempering to desired working hardness. 3^rd tempering for stress relieving. 30 - 50°C below highest tempering temperature
