Abstract：Scanning electron microscope (SEM)， electrochemical workstation， X-ray photoelectron spectroscopy (XPS)， laser in situ and transmission electron microscope (TEM) were used to study the corrosion behavior of Cu-Ni-Sn hull steel in strongly acidic chloride media. The results indicate that using Cu-Ni-Sn corrosion resistant alloy design can greatly improve corrosion resistance of hull steel in strongly acidic chloride environment， which meets the requirement of IMO. Cu can effectively enhance corrosion resistance of steel. The addition of Cu decreases corrosion rate of steel and inhibits nucleation of pitting corrosion because of the re-deposition of copper on the surface of steel. With the increase of Sn added to steel， corrosion resistance has a further improvement. It is considered to be related to the compact SnO2 protecting film on the surface of steel， which efficiently prevents the interaction between matrix and corrosion medium， then decreases corrosion rate of steel in corrosion medium.
