Assurance Of Quality Improvement For Tool Steel By Cryo-Processing, Ajit Behera

Ajit Behera

Cryo-processing, a supplementary process to conventional heat treatment, involves freezing of materials at cryogenic temperatures to enhance the mechanical and physical properties of materials. This paper deals with improvement of properties of the tool steel by cryogenic treatment and its greater life span in an industrial application. After the Second World War cryogenic technology were abandoned until the seventies when aerospace industry took up this technology again and the treatment started to be developed as a new industrial process. Today cryogenic treatment would be regarded as one of the most important processes in the field of industries, and it is …
