Continuous Cooling Transformation (CCT) Diagram

Time-Temperature Transformation (TTT) Diagram

Soft Annealing
Heat to 820-860^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 269.

Hardening
Harden from a temperature of 1000-1050^oC followed by oil or quenching. Hardness after quenching is min. 58 HRC.

Tempering
Tempering temperature: See the data bellow.

Tempering Diagram

Forging
Pre-heat to 760^oC, then bring slowly up to 1038-1204^oC before proceeding. Do not work this material below 927^oC. Cool material slowly after working and once at room temperature, anneal fully.

Machinability
Best machined in the annealed condition. Tough, stringy chips can be best handled by the use of chip breakers. Carbide or ceramic tooling is recommended.

Cold Working
This alloy is considered only slightly cold workable by common practices.

Corrosion Resistance
Resistant to a wide variety of media including fresh water, steam, petroleum products and alcohol.

Welding
This alloy is not commonly welded due to its tendency to air harden. If it must be welded, preheat to 260^oC and post weld treat at 732-760^oC for 6 hours followed by a slow furnace cooling to avoid cracking. Use similar filler metal.
