Abstract

The fatigue resistance of commercial AISI 316L and AISI 316Ti austenitic stainless steels after corrosion attack by aggressive chloride-containing environment was examined with the aim to explore the influence of pitting corrosion on their fatigue resistance. The fatigue resistance after corrosion attack was found to be significantly reduced due to the occurrence of corrosion pits on the surface of tested specimens. The obtained results were compared with results predicted using empirical model given by Murakami. It was found that the fatigue limit of the tested steels with pitting corrosion, predicted according to empirical model proposed by Murakami, is much higher than real fatigue limit experimentally determined.
