Preparation
Clean surfaces and secure workpieces to prevent deformation.
Heating
Heat to specified temperatures in controlled pace.
Soaking
Maintain temperature uniformity based on material and thickness.
Cooling
Apply quenching (water/oil) for hardness or slower cooling (annealing/normalizing) for specific microstructures.
Tempering (if needed)
Reheat to relieve stress and enhance toughness.
Inspection & Cleaning
Verify quality and remove oxidation residues.
