Soft Annealing
Heat to 640-680oC, cool slowly. This will produce a maximum Brinell hardness of 255.

Normalizing
Temperature: 850-880oC.

Hardening
Harden from a temperature of 830-860oC followed by oil quenching. Hardness after quenching is min. 54 HRC.

Tempering
Tempering temperature: 350-550oC.

Forging
Hot forming temperature: 1050-850oC. 

Machinability
No data.
