Stress Relieving is a process for making material softer. However stress relieving does not change the material properties as does annealing and normalizing.  A material can be stress relieved by heating it to a specific temperature that is lower than that of annealing or normalizing and letting it cool to room temperature inside or outside of the oven. This heat treatment is typically used on parts that have been severely stressed during fabrication. . See also, annealing, normalizing, tempering.
