Stress Relieving
STRESS RELIEVING: (300 - 1400°F)

  Thermal Stress Relieving 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.
