In this paper,the effects of NaCl concentration of dilute NaCl solutions and loading frequencies on corrosion fatigue crack growth of 0Cr18Ni9 austentic stainless steel are experimentally studied.The macroscopic and microscopic sections of the crack are observed to analysis its corrosion fatigue crack growth mechanism.
