Thermal Stress Relieving

All-Steel Stress, Blast and Coating
All-Steel Thermal Stress Relieving
In our new, state of the art industrial size stress relieving oven we can stress relieve:

  • Fabricated Weldments for post-weld heat treatment
  • Machined Parts
  • Metal Components

In addition, we provide dry-out services for paint and refractory process curing.

Our furnace will operate between 250 degrees F and 1600 degrees F.

We perform quality inspections during the stress relieving process and we can provide our customers with Certificates of Compliance and detailed Heat Charts when required.

Thermal Stress Relieving Capabilities

Our Stress Oven can accommodate customer jobs that are 12’H x 11’ W x 31’L and our rail-car capacity is 54,000lbs.

We meet the following standards:

  • ASME Section I: (900 – 1300F) Stress relieve /post -weld heat treat in accordance with ASME Sect. I, PW-39 for carbon steel weldments.
  • ASME Section VIII: (900 – 1300F) Stress relieve/post-weld heat treat in accordance with ASME Sect. VIII, USC-56 for carbon steel weldments.
  • AWS D1.1 (900-1200F): Stress relieve/post-weld heat treat in accordance with AWS D1.1, 5.8 for carbon steel weldments.
  • Westinghouse 83030QA: (1175F +/- 25F) Westinghouse-approved stress relieve procedure for carbon steel welded structures.
  • General Electric P8A-AG1, P10G-AL-0003 & 0004: (1125 – 1275F, 1125-1200F and 125-1300F) General Electric-approved stress relieve procedures for carbon steel.
  • Standard Stress Relieve: (1100-1200F) Applied to ferrous materials to reduce residual stresses for improved dimensional stability or reduced risk of premature failure in service.
  • Low Temperature Stress Relieve: (325-775F) 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.
