PROPRIETARY Uddeholm Calmax Heat Treatments
- Soft annealing: Protect the steel and heat through to 860°C (1580°F), holding time 2h. Cool in furnace 20°C/h to 770°C (36°F/h to 1420°F), then 10°C/h to 650°C (18°F/h to 1200°F) and subsequently freely in air;
Stress relieving: After rough machining the tool should be heated through to 650°C (1200°F), holding time 2h. Cool slowly to 500°C (930°F), then freely in air;
Hardening:
- Preheating: 600-750°C (1110-1380°F).
-Austenitizing temperature: 950-970°C (1740-1780°F), normally 960°C (1760°F).
Quenching media:
-Forced air/gas;
-Vacuum furnace with sufficient overpressure;
-Martempering bath or fluidized bed at 200-550°C (320-1020°F) followed by forced air cooling;
-Oil. (Quenching in oil gives an increased risk for dimensional changes and cracks; Temper the tool as soon as its temperature reaches 50-70°C (120-160°F).);
Tempering: Choose the tempering temperature according to the hardness required by reference to the tempering graph. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (360°F). Holding time at temperature minimum 2h.
Ion nitriding at 465°C (870°F) for 18 h.
Gas nitriding at 510°C (950°F) for 12 h.
Nitriding temperature should be 15-25°C (59-77°F) lower than previously used tempering temperature. - Austenitizing temperature 960°C (1760°F). Holding time 30 minutes.
