Despite the excellent performance of stainless steel in diverse application, there are media of exposure may accelerate failure of several stainless steel alloys. The possibility of this failure has to be examined by measuring the effective parameters that may result in corrosion at different rates. The present study has been conducted to examine the effect of exposing specimens of 304 stainless steel to 0.5, 1.0, 1.5 and 2.0 M chloride concentration and 70, 80, and 90 °C. Electrochemical technique of measuring the potentials and currency of the examined system has been used to collect the corrosion data. Microstructure of the specimens is examined using Scanning Electron Microscopy and X- Ray Diffraction. Both of these tests revealed no serious phase change due to exposure even at severe conditions. The potentials gained show significant effect of the operation conditions
