PROPRIETARY ExELL HOT-DIE Heat Treatments

Stress relieving: After rough machining of an annealed part, heat slowly to 1200°F (649°C), equalize and hold 1-2 hours. Furnace cool to 900°F (482°C) and then air cool to room temperature.
Annealing: With a protective atmosphere or vacuum furnace, heat slowly to 1560°F (849°C). Equalize and hold 1 hour per inch of thickness. Furnace cool 20°F (11°C)/hr to 1100°F (593°C) and equalize. Cool freely in air to room temperature. Hardness will be 217 max HB.
Preheating: Heat to 1200°F (649°C) and equalize. Continue heating to 1550°F (843°C) and equalize. Complete heating to hardening temperature.
Hardening: Typical austentizing range is 1875-1900°F (1024-1038°C). A hardening temperature of 1885°F (1029°C) is normally used for most applications. Hold at hardening temperature 30 minutes.
Quenching: Should be performed as rapidly as possible (50°F (10°C)/min) without promoting excess movement or cracking. Typical quenching media include: High speed gas with sufficient positive pressure and circulation in a vacuum furnace; Warm oil flash quench; Martempering bath or fluidized bed at 575-1020°F (302-1868°C), then air cool. Temper as soon as part reaches 120-150°F (49-66°C).
Tempering: Temper immediately after quenching to about 150°F (66°C). Temper a minimum of two times (three preferred) with intermediate cooling to room temperature. Do not temper in the range of 800-975°F (427-524°C) to avoid temper embrittleness.
