PROPRIETARY Uddeholm Ramax HH Heat Treatments

Soft annealing: Protect the steel and heat through to 740°C (1365°F). Cool at 17°C (30°F) per hour to 550°C (1020°F), then freely in air;
Stress relieving: After rough machining the tool should be heated through to max. 530°C (985°F), holding time 2 hours, then cool freely in air;
Hardening: (The steel should be annealed before hardening.) Preheating temperature: 500–600°C (930–1110°F). Austenitizing temperature: 980-1020°C (1795-1870°F). The steel should be heated through to the austenitizing temperature and held at temperature for 30 minutes. (Protect the tool against decarburization and oxidation during the hardening process.);
Quenching media: Oil, Fluidized bed or salt bath at 250-550°C (480–1020°F), then cool in air blast, Vacuum with sufficient positive pressure, High speed gas/circulating atmosphere. In order to obtain the optimum properties, the cooling rate should be as fast is possible within acceptable distortion limits. Temper the tool as soon as its temperature reaches 50-70°C (120-160°F);
Tempering: Choose the tempering temperature according to the hardness. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 250°C (480°F). Holding time at temperature minimum 2 hours. Austenitizing temperature: 1000°C (1830°F), 30 min. Holding time: 2 + 2h.
