Soft Annealing
Please ask.

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

Hardening
Quenching temperature: 975oC.

Tempering
Temperature: 600-740oC.

Forging
Hot forming temperature: 1050-850oC. 

Machinability
No data.

Forms manufactured: Please see the Dimensional Sales Program.
