Abstract Being immersed in aqueous solution with Cl~- ions,specimens made from a iow alloy steel (A537cl1)or from a stainless steel (1Cr18Ni9Ti)were tested under cyclic liad. Thetests were interrupted on schedule to measure the diameters and depths of the pits on the surfaces of the specimens. Then, by using non-linear regression method,these experimental data were expressed with five kinds of probability distribution functions. Among them lognormal function was demonstrated to be the optimal distribution function with the highest correlation coefficient (>0.99). Moreover, the probabilistic distributions and their evolution behaviours seem to coincide with the stochastic model proposed by the authors and pickering's evolution theory of pitting.
