Customer Cost Reduction through Cryogenic Treatment
The Cryogenic processing of metals and plastics is carried out with an aim to increase the performance of the materials. As part of the treatment, the material is slowly cooled from room temperature down to 196°C in a prescribed time, temperature profile. Once the temperature of –196°C is reached, the materials are soaked at this temperature for a period of 24-72 hours depending on the material being treated. On completion of the soaking period, the temperature is slowly elevated back to room temperature again as per the prescribed profile. This cryogenic processing step causes irreversible changes in the microstructure of the materials, which significantly improve the performance of the materials. The treatment calls for a precise temperature control during the processing, usually up to one-tenth of one degree, necessitating elaborate controls and sophisticated instrumentation.
Advantages of cryogenic treatment
It has been observed that the process provides the materials a stronger, denser and more-coherent structure thus increasing the abrasive resistance and thermal and electrical conductivity. For steels, the explanation of the phenomena in Layman’s terms is as follows: Super cooling the steel refines the carbides in the steel by expanding the carbide structure to fill any voids in the metal. Then as the higher temperatures return, everything relaxes into where it wants to be thus providing stability to the steel. Every step in the treatment is carefully controlled else the temperature extremes will shock the steel into delaminating.
