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
