Stress Relieving
Stress Relieving is a process in which parts are reheated to allow residual stresses from machining, forming, or prior heat treat processes to redistribute to improve dimensional stability and stress state.

A standard stress relieving process will involve heating a part and holding it below the critical temperature and then slowly cooling it. Care must be taken for hardened materials to not exceed the original tempering temperature which would decrease the strength. Controlled ramp rates and thermocouple driven control can be used when required. Care must be taken when stress relieving austenitic stainless steels to avoid the sensitization range which will decrease corrosion properties. Parts can be stress relieved in air or vacuum atmospheres. |
