PROPRIETARY D2 Tool Steel Heat Treatments
- Annealing: heat uniformly to 843/871°C (1550/1600°F), then cool very slowly in the furnace at a rate of not more than 11°C (20°F) per hour until the furnace is black.
Hardening: the hardening temperature must be in range of 982/1024°C (1800/1875°F). Without preheating, place the tool right in the hot furnace and let it heat naturally until its color uniformly matches the color of the thermocouple in the furnace. Tools should be soaked at temperature 20 minutes plus 5 minutes for each 25.4 mm of thickness, then quenched in air.
Stress Relieving: first rough machine, then heat to temperature of 649/677°C (1200/1250°F) and slowly cool.
Tempering: For the best combination of toughness and hardness, temper at 232°C (450°F). Greater ductility can be obtained by tempering at 371°C (700°F), although there will be some sacrifice of hardness. Double tempering is desired with the second temper 13.8°C (25°F) below the first temper.
