The corrosion fatigue behavior of stainless steel 3RE60 in 3.5%NaCl solution was studied at different cyclic stress levels. The results showed that both intergranular corrosion cracking and transgranular corrosion cracking initiated at the bottom of pits. The corrosion fatigue behavior of 3RE60 may be related to complex electrochemical and mechanical coupling effects between the three phases (austenite, ferrite and martensite), where martensite and ferrite were anodic in the corrosion cell and could be prone to crack under certain conditions.
