PROPRIETARY CarTech O6 Heat Treatments

  • Prior to tempering in the range of 121-604°C (250-1200°F) for 1 hour steel were oil quenched from 802°C (1475°F).
    Normalizing: Heating to 871°C (1600°F) and cooling in air.
    Annealing: Heat to 766-788°C (1410-1450°F) and hold to equalize the temperature. Cool at 11°C per hour (20°F per hour) to 593°C (1100°F) and remove from the furnace. Precautions should be taken to minimize decarburization.
    Hardening: Preheat at 649-677°C (1200-1250°F), then heat to 788-816°C (1450-1500°F) until it uniformly matches the color of the thermocouple in the furnace. Soak an additional 5 minutes per 25.4 mm of thickness and then quench in oil. Use the lower part of the hardening range for smaller sections and the higher temperatures for larger sections. The use of a controlled-atmosphere furnace or pack hardening to protect the surface from decarburization is required.
