Material subjected to deep cryogenic temperatures develop a more uniform, refined microstructure with greater density. Deep cryogenic tempering completes the metallurgical changes which heat treating begins. This process is recommended for most metals that respond to heat treating. To the eye, there is no change in the materials shape, size or structure, yet materials will last significantly longer and perform better.
Many industries can benefit from cryogenic tempering.
Austenites, the softer molecules in the structure, are transformed to harder martensites. These transformations work together to prevent wear caused by abrasion and friction. B y reducing atomic vacancies or dislocations, residual stresses and internal tensile stresses that may be placed in the material during forging and heat treating are reduced. The treated components are therefore more dimensionally stabilized compared to an untreated component. Increases durability Increases production Constant use, friction or exposure brings about the wear of any material.
