Influence of temperature and hydrodynamic conditions on the corrosion behavior of AISI 316L stainless steel in pure and polluted H3PO4: Application of the response surface methodology

► Impurities increase corrosion rates and hinder passivation and repassivation resistance of AISI 316L SS. ► Temperature increases corrosion rate according to Arrhenius plot. ► Reynolds number seems to have no influence on the corrosion rate and repassivation parameters. ► RSM proved that the effect of temperature on the corrosion rate is enhanced by the impurities. ► AISI 316L SS has proved to be an excellent component material of some equipment in the phosphoric acid industry.
