- Soft Annealing
Protect the steel and heat through to 900°C (1650°F). Cool in the furnace at 10°C (20°F) per hour to 650°C (1200°F), then freely in air.
Stress Relieving
After rough machining the tool should be heated through to 650°C (1200°F), holding time 2 hours. Cool slowly to 500°C (930°F), then freely in air.
Hardening
Pre-heating temperature: First pre-heating at 600 - 650°C (1110 - 1200°F) and second at 850 - 900°C (1560 - 1650°F). Austenitizing temperature: 1020 - 1180°C (1870 - 2160°F) Holding time: 30 minutes for hardening temperatures up to 1100°C (2010°F), 15 minutes for temperatures higher than 1100°C (2010°F).
Quenching Media
Vacuum (high speed gas at sufficient overpressure minimum 2 bar), martempering bath or fluidized bed at 200 - 550°C (390 - 1020°F), forced air/gas.
Temper the tool as soon as its temperature reaches 50 - 70°C (120 - 160°F). In order to obtain the optimum properties for the tool, the cooling rate should be as fast as possible with regards to acceptable distortion. A slow quench rate will result in loss of hardness compared with the given tempering curves. Martempering should be followed by forced air cooling if wall thickness is exceeding 50 mm.
Tempering
Choose the tempering temperature according to the hardness required. Temper at least twice with intermediate cooling to room temperature. For highest dimensional stability and ductility, a minimum temperature of 540°C (1000°F), preferably 550°C (1022°F), and three tempers is strongly recommended. Tempering at a lower temperature than 540°C (1000°F) may increase the hardness and compressive strength to some extent but also impair cracking resistance and dimensional stability. However, if lowering the tempering temperature, do not temper below 520°C (970°F). - Austenitizing temperature 1100°C (2012°F). Holding time 30 minutes.
