Where parts that are stressed out come to relax…
Stress relieving is a low temperature process designed to use heat to draw out any stresses that have been induced into the material structure via cold working, such as machining, drawing, stamping, and other deformation processes. Generally, a part that has been stress relieved can then be further worked, with an increase in dimensional stability, and be ready for the final heat treating operation to be performed, such as carburizing or nitriding. Relieving stresses can also prevent future part failures due to stress cracking and the like. The process for stress relieving involves heating the parts to a particular temperature (1100 – 1250°F) and holding until the middle of the widest cross section reaches that temperature, and then a gradual cooling to room temperature.
