5.3.1 Heat Treating

Heat treating is often employed to develop properties in the forging that could not otherwise be realized with the selected alloy. Although it is most often associated with ferrous alloys, forging alloys in all of the seven major alloy groups can be heat treated to advantage. Forgings are generally heat treated in the same processes that are used for castings and weldments.

The need for heat treating is sometimes eliminated by using an alloy that develops the required properties in the as-forged condition. For example, microalloyed steels are sometimes used to reduce or eliminate heat treating operations that would be required for carbon steels. However, the purchased price of forging stock is higher, and some additional cost may be incurred due to the requirements for additional air cooling equipment. The optimum combination of alloy and heat treatment is best developed in discussions between the forger and purchaser.

For information on specifying heat treatment, see Section 3.7.
