N2 - In this paper, rotating bending fatigue tests were carried out on plain specimens of austenitic stainless steel SUS 304 under water cooling. The processes of nucleation and propagation of cracks were clarified by successive surface observations using the plastic replica method. The main results obtained are as follows. (1) Fatigue cracks are nucleated in very small regions. (2) The fatigue crack growth rate is proportional to the crack length in a limited range. (3) I he fatigue limit corresponds to the crack initiation limit.
