Soft Annealing
Please ask.

Normalizing
Normalizing temperature: Please ask.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650^oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Please ask.

Tempering
Tempering temperature: See the data bellow.
