PROPRIETARY CarTech Micro-Melt PD#5 Alloy Heat Treatments

  • Decarburization: Steel is like all carbon-bearing tool steels, is subject to decarburization during thermal processing. However, taking proper precautions should insure that there is no decarburization during heat treatment. Salt bath, controlled atmosphere, or vacuum furnaces are acceptable for heat treating this alloy.

    Normalizing: Normalizing is not recommended for this alloy.

    Annealing: Suitable precautions should be taken to prevent excessive decarburization or carburization. Heat slowly to 843-871°C (1550-1600°F), hold until the entire mass is heated through, and cool slowly (do not exceed 17°C (30°F) per hour) in the furnace to about 538 (1000°F), after which the cooling rate may be increased.

    Hardening: Can be heat treated in salt, vacuum, or controlled atmosphere furnaces, with precautions being taken to avoid decarburization during the heat treatment operation. Preheat to 843-871°C (1550-1600°F), then transfer to 1010-1149°C (1850-2100°F). Hold 20 - 45 minutes at temperature. Following austenitizing, parts may be air cooled to room temperature. For vacuum furnace treating, a minimum 2 bar backfill with inert gas is desired for the quench.
    Stress Relieving: To relieve the stresses of machining, heat slowly to 649-677°C (1200-1250°F), hold for a minimum of 1 hour at temperature, cool slowly and uniformly to about 427°C (800°F), then cool in still air.

    Tempering: Tools should be tempered immediately after the completion of the quench. Triple tempering at 2 hours per temper is suggested, using a minimum tempering temperature of 510°C (950°F). Tools should be cooled to room temperature between tempers.
