It is important to investigate the tribological properties of corrosion-resistant materials in order to enhance the safety and reliability of offshore structures. In this study, the tribological properties of SUS304 stainless steel were examined in artificial seawater and compared with those obtained in air. The coefficient of friction was about one-half of that in air due to the lubricating effect of seawater. It was independent of normal load, but it increased with a decrease in oscillating frequency. Specific wear volume was lower than that in air by two orders of magnitude. The mild-severe wear transition against the normal load was not observed in seawater. Wear volume increased with a decrease in sliding velocity, which was contrary to the tendency obtained in air. This was caused by the significant electrochemical factor in the long testing duration.
