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 (e.g., 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:
o Solution Hardening
o Aging (Precipitation Hardening)
o Stress Relief
o Cryogenic Freezing processes
• Follow-on Processes:
o Straightening
o Batch Certification
