According to the calculation formula of corrosion fatigue crack growth rate of 0Cr18Ni9 steel in 100ppm NaCl solution, a stochastic method based on the randomness of parameters such as crack size, load and material is given. The stochastic calculation method of residual fatigue life is given. Finally, through the engineering case illustrates the method is feasible and effective
