Abstract The fatigue crack growth rate (FCGR) of 08PVXt, 16Mn, 440C and 4340 steels in distilled water anb NaClaqueous solution has been investigated, and the experimental results have been compared with those of corrosion fatigue in the literature. The fatigue life (FL) of of ordinary steels in distilled water is higher then that in NaCl aqueous solution. The FCGR of 08PVXt, 440C and 4340 steels in distilled water is higher than those in NaCl aqueous solution. However, contrary result is observed for the 16Mn steel. The authors are inclined to think that the function of the Cl~- is different in the crack initiation and in the macroscopic crack propagation.
