With the increasing development and utilization of marine resources, corrosion of structural materials of marine engineering is facing severe challenges. In this article, it is summarized the research progress on corrosion status of steel in marine environment as well as deeply analyzed such influencing mechanisms as marine atmosphere, splash zone of seawater, tidal and splash zone as well as immersion zone of seawater on corrosion behavior of steel. The main current technical measures to retard corrosion of steel in marine environment are summarized as well as development direction and application prospect in future marine engineering of new corrosion-resistant steel are discussed by discussing the effects of such environmental factors as dissolved oxygen, salinity, temperature, pH value and microorganism on corrosion rate of steel aiming to provide the technical support for improving corrosion resistance of structural materials of marine engineering.
