Abstract Four low carbon steels with different metallurgy factors have been se lected.Their susceptibility to pitting has been compared by means of polariza tion test.Characteristic of pitting initiated by different inclusions has been studied with the EPMA and the dissolving production has been confirmed with the MCT during pitting initiation.The results showed that the susceptibility of boi ling steel to pitting initiation was markedly lower than those of killed steel , the pitting susceptibility of killed steel treated by rare earth was between bo iling steel and common killed steel.The inclusions were the sites most suscepti ble to pitting initiation.Passivation film of boundary between steel matrix and inclusions was the weakest and the early pitting corrosion was caused from here .The difference of susceptibility to pitting initiated by homogeneous inclusion s was large when these inclusions existed in different kind of steels.The diffe rence of susceptibility to pitting initiated by different inclusions in the one steel was small and the sulfide inclusions had bigger ability of initiating pitt ing than other types of inclusions did.
