• Ultrasonic corrosion fatigue tests were conducted for high strength stainless steels such as YUS270, SUS304N2 and SUS329 in 3%NaCl aqueous solution. The reduction of corrosion fatigue strength at 10^9 cycles for YUS270 and SUS304N2 was not observed at all, while the reduction of giga-cycle corrosion fatigue strength was 12.5% for SUS329. Corrosion pit was observed on corrosion fatigue crack initiation area. Striation was predominantly observed on crack propagation area both in air and in 3% NaCl aqueous solution. It can be concluded that the reduction of corrosion fatigue strength of 2.5%Mo containing high strength austenitic stainless steels is due to the corrosion pit formation at corrosion fatigue crack initiation area.
