Alternatives to “Stress Relief” Heat Treatment

Several alternatives to conventional stress relief heat treatment are available, although they are considered to be inferior, and are therefore only rarely used. These alternatives include:

1. Higher preheat temperatures for carbon and carbon-moly steels
2. Temper bead (also called half-bead) welding for carbon, carbon-moly, and manganese-moly steels
3. Peening
4. Vibrational stress relief

A discussion of each of these alternatives is included in Section 100 of the Welding Manual. The limitations of each alternative should be understood before accepting the alternative in lieu of conventional stress relief heat treatment.
