In this research the synergistic effect of environmental factors on corrosion rate of austenitic stainless steels 304 and 316 has been assessed. The behavior and resistance of these alloys are studied in aerated synthetic seawater, using potentiodynamic polarization scan. The salinity, velocity, pH and temperature are the considered parameters. To study the individual and interactive contribution percentage of parameters on changing the average value of corrosion rate, a quantitative full two-level factorial experimental design method is applied. Beside this quantitative analysis, qualitative analysis has been used to predict the variation direction. By means of these two analyses we can predict the magnitude and quality of each parameter’s effect. This research has a potential in prediction of alloys’ behavior, which is really valuable in marine engineering designs.
