Heat Treatment
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 1020°C (1870°F). Holding time: 30 minutes (10 minutes at 1100°C (2010°F) and above. 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.
Tempering: For cold work applications tempering should always be carried out at 560°C (1040°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. The retained austenite content will be less than 3% after this tempering cycle.
