PROPRIETARY Carpenter Stainless Type 431 Heat Treatments


  • Annealing: Heat uniformly to 650 - 677°C (1200 - 1250°F) - remove charge from furnace and cool in air. Brinell approximately 270. This treatment will be best for most machining operations.
    Hardening: Heat to 982 - 1066°C (1800 - 1950°F), soak at heat, quench in oil. This grade will also harden by cooling in air. When tempering below 371°C (700°F), the high side of the hardening range should be employed for the best impact strength. Lower hardening temperatures should be used when tempering above 538°C (1100°F) for best impact strength.
    Tempering: Temper to secure hardness and mechanical properties desired. Soak at heat at least one hour, and longer for larger pieces - cool in air. Tempering in the range of 371 - 565°C (700 - 1050°F) results in decreased impact strength and corrosion resistance.
