Stress Relieving Heat Treatment
Precision Stress Relieving Solutions for Machined and Welded Components
Reduce Internal Stresses, Improve Dimensional Stability
Even the most precise manufacturing processes can leave behind residual stresses. If left untreated, these internal tensions can cause distortion, cracks, or failure—especially after machining or welding. That’s why stress relieving is an essential step in ensuring the long-term reliability of your metal components.
At Fiesco Precision, we offer stress relieving heat treatment designed to improve dimensional stability, reduce material fatigue, and prepare your parts for high-performance applications.
What Is Stress Relieving?
Stress relieving is a thermal process that involves heating metal parts to a temperature below the material’s transformation point (typically 1050°F–1300°F for steels), holding them for a specific period, and then cooling them slowly.
The goal? To reduce or eliminate residual stresses caused by prior manufacturing processes such as:
- Machining
- Welding
- Cold working
- Casting
Forming
Why Stress Relief Is Critical
Residual stresses can make your parts behave unpredictably during later stages of production or use. Without stress relieving, you risk:
- Part warping or distortion during final machining
- Stress corrosion cracking
- Reduced fatigue strength
- Unwanted dimensional changes in service
Fiesco’s controlled environment and precision ovens ensure that your parts maintain integrity, dimensional accuracy, and performance after treatment.
Benefits of Stress Relieving
✔️ Enhanced dimensional stability
✔️ Prevention of future distortion
✔️ Improved fatigue and corrosion resistance
✔️ Easier post-treatment machining
✔️ Longer part lifespan
Benefits of Stress Relieving
Stress relieving is a critical step in the production of components for industries such as:
- Aerospace – precision-machined brackets and mounts
- Automotive – crankshafts, gears, and welded structures
- Tooling – dies, molds, and fixtures
- Construction & Structural – pressure vessels, beams, and weldments
- Medical – surgical equipment and supports
If your part is exposed to further machining, harsh environments, or close-tolerance assembly—stress relieving is a must.

Our Process at Fiesco Precision
- Part Evaluation
We assess material type, geometry, and previous processes to determine the right stress relief cycle. - Controlled Heating
The part is heated slowly in a uniform, digitally-controlled furnace to avoid introducing thermal gradients. - Soak Time
We hold the part at the target temperature long enough to relieve internal stress across the entire geometry. - Controlled Cooling
The part is cooled inside the furnace at a controlled rate to avoid introducing new stress.
Final Inspection
Our team inspects the part for flatness, hardness, and surface integrity before releasing it for the next step.
Build the Foundation for Precision
Parts treated with stress relief behave better, last longer, and allow for tight tolerance machining with fewer surprises. It’s an invisible but essential part of high-quality manufacturing.
At Fiesco Precision, we don’t just remove stress—we create confidence. Let us help you build a better, more stable product from the inside out.
