MIL S-24093A Type III Class F Heat Treatments


  • Class shall be either normalized and tempered or quenched and tempered, in their final heat treated condition. Tempering temperature shall not be below 565°C (1050°F); Stress relieving: At the discretion of the contractor or when specified by the contracting activity a stress relief treatment may be performed on forgings after final machining, in which, case the stress relief temperature shall be at least 10°C (50°F), below the tempering temperature applied to the forging. In cases where weld repairs have been performed after final heat treatment, the need for stress relief shall be judged by the contracting activity.
