Cryogenic processing is a technique that involves cooling materials to extremely low temperatures, typically below -150 degrees Celsius. This process alters the physical properties of metals and other materials, enhancing their strength, durability, and resistance to wear. It is commonly used in industries such as aerospace, automotive, and manufacturing to improve the performance of tools and components. During cryogenic processing, materials are gradually cooled using liquid nitrogen or other cryogenic fluids. The low temperatures cause changes in the microstructure of the material, reducing residual stresses and improving overall performance. This method is often applied to steel, aluminum, and other alloys to extend their lifespan and efficiency in various applications.
