PROPRIETARY 17-4 Stainless Heat Treatments

  • Condition A: Heated at 1038°C ± 14°C (1900°F ± 25°F) for 1/2 hour, air (Solution Treated) cooled or oil quenched to below 32°C (90°F). Normally performed at mill. For most applications, 17-4 stainless should not be used in Condition A.
    H900: Condition A material heated at 482°C ± 8°C (900°F ± 15°F) for 1 hour and air cooled. Maximum hardness but low toughness. Sensitive to stress corrosion cracking.
    H925, H1025, H1075, H1100, H1150: Condition A material heated 4 hours at specific temperature, and air cooled.
    H1150D: Condition A material heated 4 hours at 621°C (1150°F), air cooled, heated again for an additional 4 hours at 621°C (1150°F) and air cooled.
    H1150M: Condition A material heated at 760°C ± 14°C (1400°F ± 25°F) for 2 hours, air cooled, then heated at 621°C ± 8°C (1150°F ± 15°F) for 4 hours and air cooled.
    At the solution treating temperature, 1038°C (1900°F), the metal is austenitic but undergoes transformation to a low-carbon martensitic structure during cooling to room temperature. This transformation is not complete until the temperature drops to 32°C (90°F). Subsequent heating to temperatures of 482-621°C (900-1150°F) for one to four hours precipitation strengthens the alloy. This hardening treatment also tempers the martensitic structure, increasing ductility and toughness.
