Oct 13, 2020 The cryogenic treatment of heat-treated metal is a one-time, permanent process that helps to eliminate residual stresses in metal components. Residual stress in materials is caused by a variety of things, including the actual formation of the metal, machining or casting, and the heat treatment process itself.

Mar 27, 2017 Cryogenic treatment is also used as a form of stress relieving. Regardless of whether the metal is aluminum, copper, steel or cast all metals have some amount of residual stresses created when the metal changes from its molten state into its solid form. As the cooling process takes place, natural stress fractures occur.
All metals not just steel, (aluminum, copper, cast alloys, etc.) will benefit from residual stress relieving as a result of Deep Cryogenic Treatment. All metals have residual stresses; they are created from the moment the metal reezes from its molten form into its solid form.
