Heat treatment

ForgingHeat to 1150°C. Hold until uniform. Minimum forging temperature 850°C.Cool slowly in ashes or sand etc.
AnnealingHeat to 830°C-850°C.Cool in furnace.
NormalisingHeat to 870°C-900°C.Cool in still air.
Stress RelievingAnnealed: Heat to 600°C-650°C.Hardened: Heat to 500°C-550°C.Cool in still air.
HardeningHeat to 830°C-880°C. Quench in oil or polymer.
TemperingHeat to 450°C-700°C cool in still air. NB. Tempering within the range 200°C-420°C will result in temper brittleness and should be avoided.
