Subha Vacuum- Stress Relief in Metals and Alloys

Stress Relieving

Stress relief is a heat treatment process used to reduce residual stresses in materials, typically metals and alloys, that have been subjected to prior mechanical processes such as machining, welding, or cold working. The primary purpose of stress relieving is to improve the material's dimensional stability and reduce the risk of distortion or cracking.

The main objectives of stress relieving are to:

Reduce residual stresses that may have been introduced during prior manufacturing processes.

Minimize the risk of dimensional changes or distortion in the material.

Enhance the material's stability and reduce the likelihood of cracking or deformation in service.

The specific stress relieving parameters, including heating temperature and soaking time, are determined based on the material type, its prior processing history, and the level of residual stresses to be relieved.
