What Is Stress Relief Heat Treatment?
Table of Contents
Stress relief is a heat treatment process that removes internal residual stresses in metals introduced during welding, machining, forging, casting, or cold-working operations. It involves heating the component to a sub-critical temperature (typically between 400°C and 700°C) and holding it at that temperature for a calculated time before controlled cooling.
Benefits of Stress Relief Heat Treatment:
-
Reduces risk of distortion or cracking
-
Improves dimensional stability
-
Enhances fatigue resistance
-
Prepares component for subsequent processing or finishing
-
Essential for compliance in pressure vessel and structural applications
As leading stress relief furnace manufacturers India, we ensure that every system includes programmable temperature cycles, airflow uniformity, and digital safety interlocks for accurate process control.
