Effect of Cryogenic Treatment On 17-4 Ph Steel

The research paper focuses on the effect of cryogenic treatment on 17-4PH Precipitation-hardening martensitic stainless steels. 17-4PH is a versatile material, widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries. The two main characteristics of this steel are high strength and high corrosion resistance. Recent studies on certain alloys showed variation in residual stress after cryogenic treatment. Lot of published cryogenic treatment articles claims benefits without showing scientific evidence. This is a drawback for commercializing the process. Hence an attempt has been made to study the wear resistance of cryogenically treated 17-4PH.  X-Ray diffraction studies were also carried out to identify the mechanism involved.
