Understanding Cryogenic Treatment
Cryogenic treatment involves cooling materials to cryogenic temperatures, typically below -150°C (-238°F), using liquid nitrogen or other cryogenic fluids. The extreme cold temperatures cause changes in the material’s microstructure, such as the transformation of retained austenite in steel to martensite, resulting in enhanced mechanical properties. This treatment is often used to improve the performance and lifespan of tools, components, and machinery.
