This alloy may be readily forged, headed or upset. It requires more blows or a heavier hammer than does mild steel. It should be heated uniformly to 2000/2200ºF (1095/1205ºC), depending upon the degree of deformation, then forged and air cooled. Large forgings should be furnace cooled or cooled in dry lime. This grade should not be forged below 1650ºF (900ºC).
Parts should be heated uniformly to 1200/1400ºF (650/760ºC) and air cooled. Optimum machinability is obtained by a lowering of the annealing temperature to give a slightly higher hardness. For maximum softness heat to 1500/1650ºF (815/900ºC) and slow furnace cool to give approximately 155 BHN. Maximum softness may be required for subsequent cold forming, for cold heading for instance.
Heat to 1750/1850ºF (955/1010ºC), soak and quench in oil or air cool.
Temper at temperatures appropriate to produce desired mechanical properties. Soak for at least one hour, longer for larger sections, and air cool.
If this alloy is tempered in the range 750/1050ºF (400/565ºC) there will be a decrease in impact
