Soft Annealing
Heat to 750-880oC, cool slowly in furnace or air. Structure is ferrite with spherical carbides. This will produce a maximum Brinell hardness of 250.

Harden from a temperature of 980-1050oC followed by oil quenching. Hardness after quenching is 49 HRC.

Tempering temperature: 150-200oC, 650-750oC

Hot forming temperature: 1100-800oC, slow cooling. 

Metal-cutting machining is the same as for special engineering steel grades of corresponding strength.

Limited weldability using the manual arc and TIG welding processes, as hardening occurs in the heat-affected zone. Preheat to between 300 and 400oC. Filler metals: 1740, Nicro82.
