The influence of deformation temperature, strain rate and alloying elements such as chromium, nickel, copper, on corrosion resistance of a 304 stainless steel after plastic deformation was investigated. The techniques employed were tensile test at room and elevated temperature, deep drawing tests at various strain rates, X-ray diffraction test and potentiodynamic and cyclic polarization, metallography by optical and scanning electron microscopy. Results showed that chromium, nickel and copper had a significant effect on corrosion resistance of steel after plastic deformation. It was observed that corrosion resistance after plastic deformation was a function of deformation temperature and alloying elements.
