PROCESSING

Soft Annealing
Heat to 610-650oC, cool slowly. This will produce a maximum Brinell hardness of 229.

Hardening
Case-hardening: 880-980oC, oil (water), warm bath at 160-250oC. Carburising: Salt bath at 580-650oC, case-hardening box, air.
Direct hardening: 880-890oC, oil, hot bath at 160-250oC.
Core refining: 840-880oC, oil, hot bath at 160-250oC.
Case refining: 780-820oC, oil, hot bath at 160-250oC.

Normalizing
Normalizing temperature: 850 – 880oC.

Tempering
Tempering temperature: 150 – 200oC.

Forging

Hot forming temperature: 1050-850oC.
