9.HeatTreatment

Annealing

Heat to 800°C-850°C hold until temperature is uniform throughout the section,and cool in furnace.

Hardening

Heat to 800°C-850°C 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 830°C -860°C soak as above and quench in oil.Temper immediately while still hand warm.

Tempering

Re heat to 400°C-650°C as required,hold until temperature is uniform throughout the section,soak for 1 hour per 25mm of section,and cool in still air.
