Cryogenic processing is a special type of heat-treating process that involves cooling heat-treated steels and other metals to temperatures lower than -185°C. The deep chilling of heat-treated parts allows the metal molecules to be brought to “cryogenic stillness” to improve wear characteristics.

This treatment is performed by slowly cooling the parts in a controlled bath of liquid nitrogen or other refrigerant, and holding the parts until the temperature has reached the target temperature, then returning the part to room temperature.

Cryogenic hardening is able to make metal objects and work pieces more resistance to wear and tear. Metal doesn’t just become harder through cryogenic hardening; it becomes tougher and more resistant to wear. As a result, cryogenic hardening is performed to increase the usable life of metal objects and work pieces.
