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.

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

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

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

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

Welding 
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.
