PROPRIETARY Uddeholm Dievar Heat Treatments

Unless otherwise is indicated all specimens have been hardened at 1025°C (1875°F), quenched in oil and tempered twice at 615°C (1140°F) for two hours.
Soft annealing: Protect the steel and heat through to 850°C (1560°F). Then cool in furnace at 10°C (20°F) per hour to 600°C (1110°F), then freely in air;
Stress relieving: After rough machining the tool should be heated through to 650°C (1200°F), holding time 2 hours. Cool slowly to 500°C (930°F), then freely in air;
Hardening: Preheating temperature: 600-900°C (1110-1650°F). Normally a minimum of two preheats, the first in the 600-650°C (1110-1200°F) range, and the second in the 820-850°C (1510-1560°F) range. When three preheats are used the second is carried out at 820°C (1510°F) and the third at 900°C (1650°F). Austenitizing temperature: 1000-1030°C;
Quenching media:
-High speed gas/circulating atmosphere
- Vacuum (high speed gas with sufficient positive pressure). An interrupted quench at 425-450°C (800-840°F) is recommended where distortion control and quench cracking are a concern
- Martempering bath, salt bath or fluidized bed at 450–550°C (840-1020°F) or 180-200°C (360-390°F)
- Warm oil, approx. 80°C (180°F). 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 minimum three times for die casting dies and minimum twice for forging and extrusion tools with intermediate cooling to room temperature. Holding time at temperature minimum 2 hours. Tempering in the range of 500-550°C (930-1020°F) for the intended final hardness will result in a lower toughness.
Austenitizing temperature 1025°C (1877°F). Holding time 30 minutes.
