The present work deals with the cryo-rolling of 304 austenitic stainless steel and its corrosion behavior. Austenitic Stainless Steel (304 grade) finds wide applications in chemical, petrochemical, construction and transportation industries. As received Austenitic stainless steel have been cryo-rolled to various degree of plastic deformation (30, 50, 70 & 90%). Microstructural, tensile, hardness and corrosion behaviour of undeformed and deformed samples were conducted. Magnetic measurements were also conducted to confirm the formation of martensitic phase leading to the strengthening of the steel. The tensile strength, hardness were found to increase with the extent of cryo-rolling. The ultimate strength has increased from 693 MPa (before deformation) to 1956 MPa (after 90% deformation), and hardness too has increased from 206 Vickers (before deformation) to 520 Vickers (after 90% reduction), however the loss in ductility was observed.
