AISI 630 Heat Treatments

  • Solution treated at 1040 ± 15°C (1900 ± 25°F), cooled as required to below 32°C (90°F).

    Hardening:

    Time refers to minimum time material is at temperature and may be extended to obtain required ductility properties.

    Unless otherwise noted, temperatures shown are suggested temperatures and may be varied to obtain required tensile properties.

    Intermediate temperatures must meet the ductility requirements of the next highest suggested hardening or aging temperature, or both.

    When air cooling is specified, gases other than air may be used.

    H900: Heated at 480°C (900°F), 1h, cooled in air.

    H925: Heated at 495°C (925°F), 4h, cooled in air.

    H1025: Heated at 550°C (1025°F), 4h, cooled in air.

    H1075: Heated at 580°C (1075°F), 4h, cooled in air.

    H1100: Heated at 595°C (1100°F), 4h, cooled in air.

    H1150: Heated at 620°C (1150°F), 4h, cooled in air.

    H1150M: Heated at 760°C (1400°F), 2h, cooled in air, plus heated at 620°C (1150°F), 4h, cooled in air.

    H1150D: Heated at 620°C (1150°F), 4h, cooled in air, plus heated at 620°C (1150°F), 4h, cooled in air.
  • Class 1
    Austenitizing: 1024-1052°C (1875-1925°F), air or liquid quenching;
    Aging: 613-629°C (1135-1165°F);
    Stress relieving: Minimum 593°C (1100°F).
