PROPRIETARY S7 Alloy Tool Steel Heat Treatments
- Annealing: Heat to 816/843°C (1501/1549°F) and cool very slowly in the furnace at a rate of not more than 11°C (20°F) per hour to a temperature below 538°C (1000°F), then allow to cool naturally. This will produce a maximum hardness of Brinell 223; Hardening: May be hardened by placing them in the furnace maintained at a temperature of 927/954°C (1701/1749°F). Let the tools heat naturally to the furnace temperature, soak for 20 min. plus 5 min. per 25.4 mm of max. thickness and quench. Sections up to 64.5 mm thick may be cooled in air. Heavier sections, i.e., with section thickness larger than 64.5 mm, should be oil quenched to 66°C (151°F); Stress relieving: Anneal below the critical at 649/677°C (1200/1251°F), a minimum of one hour at temperature and cool slowly; Tempering: The best combination of hardness and toughness is obtained by tempering at about 204°C (399°F). This tempering temperature is therefore suggested for cold-work applications. Tempering at 482/538°C (900/1000°F) is usually desirable for hot-work applications.
