HEAT TREAT/STRESS RELIEVING
Heat treatment is a method used to alter the physical and, occasionally, chemical properties of a material. The most common application is metallurgical. Heat treatment involves the use of heating or chilling to extreme temperatures in order to achieve a desired result, such as the hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, and quenching. Inadvertent heating and cooling often occur incidentally throughout other manufacturing processes such as metal forming, machining, or welding. Following particular machining operations that can often create stress in already hardened work pieces, Wolverine Carbide and Tool will also utilize a stress relief process to mitigate stress points that can occur.  These stress relieving processes help to increase tool life.
