Description
6: HEAT TREATMENT
ANNEALINGFull annealing of small C1050 forgings is carried out from 1450-1600oF (790-870oC)
followed by furnace cooling at 50oF (28oC) per hour, to 1200oF (650oC) soaking and air cooling.
NORMALIZING
The normalizing temperature range for this grade is typically 1650-1700oF (900-925oC.)
Normalizing is followed by cooling in still air. When forgings are normalized before hardening and tempering or other heat treatment, the upper range of the normalizing temperature is used. When normalizing is the final treatment, the lower temperature range is used.
HARDENING
Hardening of this grade is carried out from an austenitizing temperature of 1500-1600oF (820-870oC) followed by oil or water quenching.
Flame and induction hardening may be carried out by heating quickly to the desired case depth and quenching in water or oil. This should be followed by a tempering treatment at 300-400oF (150-200oC) to reduce stresses in the case, without affecting its hardness. A surface hardness as high as Rc 61 may be obtained from C1050 by this treatment.
TEMPERING
Tempering after normal hardening and oil or water quenching is carried out at 750-1260o F (400-680oC) to give the required mechanical properties as determined by practical experience.
