PROPRIETARY Uddeholm Impax Supreme Heat Treatments

  • Soft annealing: Protect the steel and heat through to 700°C (1300°F). Then cool in the furnace at 28°C (50°F) per hour to 600°C (1110°F), then freely in air;
    Stress relieving: After rough machining the tool should be heated through to 550°C (1020°F), holding time 2 hours. Cool slowly to room temperature;
    Hardening: (The steel should be fully soft annealed before hardening.) Preheating temperature: 500-600°C (930-1110°F). Austenitizing temperature: 850°C (1560°F). The steel should be heated through to the austenitizing temperature and held at temperature for 30 minutes. (The tool need to be protected against decarburization and oxidation during the hardening process.);
    Quenching media: High speed gas/circulating atmosphere (Only suitable for small dimensions), Oil (60-80°C/140-175°F), Martempering bath 300°C (570°F) max. 4 minutes, then air. (Temper immediately tool reaches 50-70°C (120-160°F);
    Tempering: The tempering temperature is according to the hardness required. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (360°F) for small inserts, but preferred minimum is 250°C (480°F). Holding time at temperature minimum 2 hours.
    Nitriding and Nitrocarburizing: prior to nitriding material should be rough machined, stress tempered at 550°C (1020°F) and grinded. Gas nitriding at 525°C (977°F) for 20 h and depth of case 0.30 mm or 30 h and depth of case 0.35 mm. Ion nitriding at 480°C (896°F) for 24 h and depth of case 0.30 mm or 48 h and depth of case 0.40 mm. Nitrocarburizing at 570°C (1058°F) for 2 h and depth of case 0.10 mm.
