Stress relieving of steel components and welded fabrications is an important process step in the manufacture of many steel components.
It is usually done after rough machining but before final machining or a finishing operation such as gear cutting, grinding or polishing.
Parts that have tight dimensional tolerances must be stress relived if those tolerances are to be maintained after further processing.
Welded fabrications can be made stress-free by stress relieving.
Non-ferrous alloys, copper, brass and aluminium, are stress relieved at a wide variety of temperatures related to alloy type and condition.
