Stress Relieving

The main advantages of Stress Relieving process to minimize residual stresses in the structure thereby reducing the risk of dimensional changes during further manufacturing or before the final use of the component.

Stress relieving is a heat treatment process in which a metal is subjected to a constant temperature that is below the metal's critical temperature, followed by controlled cooling.

Drawing, forming and machining induce stresses in materials. A stress relief operation is typically used to remove internal (residual) stresses that have accumulated in the material. These stresses can cause loss of tolerance, cracking and distortion, and contribute to in-service failures. For these reasons, stress relieving is often necessary or even mandatory.
