Vacuum Stress relieving leaves the structure of the material unchanged but removes any work induced stress that could cause dimensional instability during subsequent processing. As such, stress relieving is usually carried out after rough machining but before final machining to allow tighter tolerance on final parts, and is used when fully annealing is not necessary.
This process is useful for relieving stresses and tension built up in joints during welding and machining processes. Though not always strictly necessary, we stress relieve all parts in vacuum to ensure they are processed in highly controlled, repeatable environment, delivering first-rate, contaminant free results every time.
