Thermal Stress Relieving
Thermal stress relieving is the most popular heat treatment method offered by Pittsburgh Metal Processing Co.
It is generally applied to metallic materials that have been cold-worked, formed, machined, flame-cut or weld-fabricated to reduce residual stresses for dimensional stability or reduced risk of premature failure in service.
- ASME Section I: (900 - 1300°F)
Stress relieve/Post-Weld Heat Treat in accordance with ASME Section I, PW-39 for carbon steel weldments.
- ASME Section VIII: (900 - 1300°F)
Stress relieve/Post-Weld Heat Treat in accordance with ASME Section VIII, UCS-56 for carbon steel weldments.
- AWS D1.1: (900 - 1200°F)
Stress relieve/Post-Weld Heat Treat in accordance with AWS D1.1, 5.8. for carbon steel or quench and tempered weldments.
- Westinghouse 83030QA: (1175°F ± 25°F)
Westinghouse-approved stress relieve procedure for carbon steel welded structures.
- General Electric P8A-AG1, P10G-AL-0003 & -0004: (1125 - 1275°F, 1125 - 1200°F, and 1250 - 1300°F)
General Electric-approved stress relieve procedures for carbon steel.
- Standard stress relieve: (1100 - 1200°F)
Typically applied to ferrous materials to reduce residual stresses for improved dimensional stability or reduced risk of premature failure in service.
- Low-temperature stress relieve: (325 - 775°F)
Typically applied to stainless steel and aluminum welded fabrications to reduce residual stresses with little or no effect of the corrosion resistance and/or mechanical properties.
