- Soft annealing:
Protect the steel and heat through to 900°C (1650°F). Then cool in the furnace at 10°C/h (20°F/h) to 650°C (1200°F), then freely in air.
Stress relieving:
After rough machining the tool should be heated through to 600–700°C (1110–1290°F), holding time 2 hours. Cool slowly to 500°C (930°F), then freely in air.
Hardening:
Pre-heating in two stages: 600–650°C (1110–1200°F) and 850–900°C (1560–1650°F). Austenitizing temperature: 950–1150°C (1740–2100°F), normally 1080°C (1980°F). Holding time: 30 minutes (10 minutes at 1100°C (2010°F) and above). Sub-zero treatment is recommended when a hardening temperature of 1100°C (2010°F) or above has been used.
Sub-zero treatment:
For the highest requirements on dimensional stability sub-zero treatment is recommended after quenching. The tool should be sub-zero treated immediately after quenching to at least -70°C (-95°F), soaking time 1–3 h, followed by three temperings at 540°C (1000°F) for 1 hour. For a high hardening temperature, >1080°C (1980°F), sub-zero treatment followed by three temperings at 520°C (970°F) for 1 hour is always recommended in order to minimize the retained austenite and improve the dimensional stability.
Quenching media: Vacuum furnace with high speed gas at sufficient overpressure (2–5 bar); Martempering bath or fluidized bed at approx. 550°C (1020°F); Forced air/gas.
Quenching should be continued until the temperature of the tool reaches approx. 50°C (120°F). The tool should then be tempered immediately. For applications where maximum toughness is required use a martempering bath or a furnace with sufficient overpressure.
Tempering:
For cold work applications tempering should always be carried out at 540°C (1000°F) irrespective of the austenitizing temperature. Temper three times for one hour at full temperature. The tool should be cooled to room temperature between the tempers. - Austenitizing temperature 1080°C (1980°F). Holding time 30 minutes.
