stress relieving
Stress Relieving helps reduce internal stresses in metal parts produced by machining, welding, or cold working. It aims at greater dimensional stability and performance of the metal. It has traditionally been applied to both ferrous and non-ferrous metals.
Key features:
- Controlled Heating: The metal is heated to a predetermined temperature below its critical point, thereby avoiding change in structure.
- Slow Cooling: The heated metal is then slowly cooled in air or in a furnace to dissipate the internal stresses accumulated.
- Dimensional Stability: Reduces distortion and improves structural integrity within the metal.
Stress relief is mainly to improve longevity and use of metal components under mechanical or thermal loads. Uses include aerospace, automotive, and construction industries. Modern stress-relieving techniques have given accuracy and effectiveness in metal processing.
