Enhancing the Wear Resistance of Case Carburized En 353 Steel by Cryogenic Treatment

Cryogenic treatment has been used to improve the wear resistance of materials because it enhances the transformation of austenite (soft phase of iron) to martensite (hard phase of iron).  It is a one-time permanent process and it affects the entire cross-section of the material usually done at the end of conventional heat treatment process but before tempering.
