PROPRIETARY Uddeholm Idun Heat Treatments
- It is intended for use in the as-delivered condition, i.e. hardened and tempered to 42–46 HRC. When the steel is to be heat treated to a higher hardness, instructions below are to be followed.
Soft annealing: Protect the steel and heat through to 780°C (1430°F). Cool at 28°C (50°F) per hour to 600°C (1110°F), then cool freely in air.
Stress relieving: After rough machining, the component should be heated through to max. 500°C (930°F), holding time 2 hours, then cool freely in air.
Hardening: It is recommended to do soft annealing before hardening. Preheating temperature: 500–600°C (930–1110°F). Austenitizing temperature: 980–1000°C (1800– 1830°F) but usually 980°C (1800°F). The steel should be heated through to the austenitizing temperature and held at temperature for 30 minutes. Protect the component against decarburization and oxidation during the hardening process.
Quenching media: Vacuum with sufficient positive pressure; High speed gas/circulating atmosphere. In order to obtain the optimum properties, the cooling rate should be as fast as possible within acceptable distortion limits. Temper the component 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 minimum twice with intermediate cooling to room temperature. Lowest tempering temperature 250°C (480°F). Holding time at temperature minimum 2 hours.
