Stress Relieving Hardening & Tempering is a combined heat treatment process used to eliminate internal stresses caused by machining, welding, or cold working. The process begins with controlled heating of the material followed by hardening to increase strength. It is then tempered at a lower temperature to achieve improved toughness and stability. This method enhances dimensional accuracy, reduces distortion risk, and ensures that metal components can perform reliably under mechanical load or thermal cycling.
