PROPRIETARY Uddeholm Stavax ESR Heat Treatments
- Soft annealing: Protect the steel and heat through to 890°C (1630°F). Then cool in the furnace at 20°C (36°F) per hour to 850°C (1560°F), then at 10°C (18°F) per hour to 700°C (1290°F), then freely in air;
Stress-relieving: After rough machining the tool should be heated through to 650°C (1200°F), holding time 2 hr. Cool slowly to 500°C (930°F), then freely in air;
Hardening: Preheating temperature: 600-850°C (1110-1560°F). Austenitizing temperature: 1000-1050°C (1830-1920°F), but usually 1020-1030°C (1870-1885°F).
Quenching media: 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 optimum properties, the cooling rate should be as fast as is concomitant with acceptable distortion. When heat treating in a vacuum furnace, a 4-5 bar overpressure is recommended. Temper immediately when the tool 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 for minimum of 2 h. - Austenitizing temperature 1030°C (1890°F). Holding time 30 minutes.
