Forging | Pre heat to 750ºC - 800ºC, then continue heating to 1100ºC - 1200ºC maximum, hold until temperature is uniform throughout the section and commence forging immediately |
Annealing | Heat to 800ºC - 850ºC hold until temperature is uniform throughout the section, and cool in furnace |
Hardening | Heat to 820ºC - 850ºC hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25mm of section, and quench in water or brine. or: Heat to 830ºC - 860ºC soak as above and quench in oil.Temper immediately while still hand warm |
Normalizing | Heat to 870ºC - 920ºC hold until temperature is uniform throughout the section, soak for 10 - 15 minutes.Cool in still air |
Tempering | Re heat to 400ºC - 650ºC as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25mm of section, and cool in still air. |
