Heat Treatment Processes

The Heat Treatment process group includes multiple types of Heat Treatment processes and follow-on processes for both ferrous and non-ferrous materials:

  • For Ferrous materials: Surface (Case) Hardening: Carburizing, Carbonitriding, Induction Hardening

  • Through Hardening: Atmospheric Oil Hardening, Vacuum Air Hardening with/without High Temper, and material-specific hardening processes for spring steel, stainless steel, and high-speed steel

  • Annealing: Standard, Low Temperature Vacuum, and High Temperature Vacuum

  • Tempering processes: Standard Temper and Vacuum Temper, plus an Additional Temper process. Additional Temper is intended for use following an earlier process which includes tempering (for example, Carburizing includes a tempering step, or if Standard or Vacuum Temper processes were employed previously).

  • Age: for Bar & Tube parts that use extruded stock.

  • For Non-Ferrous materials:

    • Solution Hardening

    • Aging (Precipitation Hardening)

    • Stress Relief

    • Cryogenic Freezing processes

  • Follow-on Processes:

    • Straightening

    • Batch Certification
