Abstract
Giga-cycle corrosion fatigue behavior of 12 Cr martensitic stainless steels in NaCl and NaOH aqueous solution were summarized mainly on the basis of the author's experimental results. Then giga-cycle corrosion fatigue behavior of austenitic stainless steels such as SUS304,SUS304N2, SUS316, 2.5%Cr containing steel and YUS270 super stainless steel are demonstrated on the basis of the author's recent experimental results. Giga-cycle corrosion fatigue behavior of SUS329 duplex stainless steel is touched on briefly. The reduction of giga-cycle corrosion fatigue strength of stainless steels is depending on the kind of stainless steel. It can be concluded that the reduction of corrosion fatigue strength of martensitic, austenitic and duplex stainless steels is due to the corrosion pit formation at corrosion fatigue crack initiation area.
