Stress Relieving Springs

Stress relieving springs is the most common form of heat-treating springs. This video shows two large batch ovens used for stress relieving larger springs in large batch quantities. Smaller springs can be stress relieved in an in-line furnace. If not properly stress relieved, a spring can hold residual stresses that may later lead to cracking, distortion, and ultimately failure. It is important that stress relief furnaces are calibrated on a regular basis to ensure that springs are being heat treated properly. Just as important as the heating process is the cooling process. Springs must cool at a slow rate to avoid additional stresses which may cause microscopic structure changes, leading to possible fatigue or failure.
