PROPRIETARY CarTech A6 Tool Steel Heat Treatments
- Prior to tempering in the range of 93-538°C (200-1000°F) for 1 hour steel were air quenched from 843°C (1550°F).
Annealing: It should either be packed in a suitable container, using a neutral packing compound, or placed in a controlled atmosphere furnace. Heat uniformly to 732 - 746°C (1350 - 1375°F) and cool very slowly in the furnace at a rate of not more than 11°C (20°F) per hour until the furnace is black. The furnace may then be turned off and allowed to cool naturally.
Hardening: First, heat the salt bath or furnace to 830 - 871°C (1525 - 1600°F), depending upon the size of the tool. Without preheating, place the tool in the hot furnace and let it heat "naturally" until it uniformly matches the color of the thermocouple in the furnace. Soak for 20 minutes at temperature, and an additional 5 minutes per 25.4 mm of thickness, then remove from the furnace and cool in a free circulating air.
Stress Relieving: To relieve machining stresses for greater accuracy in hardening, first rough machine, then heat to a temperature of 649-677°C (1200-1250°F), and cool slowly. After cooling, parts may be finish machined.
