Research and development of new pipeline steels with resistance to microbiologically influenced corrosion

With increase of the pipeline failure cases caused by microbiologically influenced corrosion (MIC), it is of great engineering significance to develop new measures for MIC mitigation. The Cu bearing pipeline steel is a novel strategy for MIC mitigation from the material design aspect, which has shown good MIC resistance. Based on the previous reports, this review mainly summarizes the research progresses on phase transformation kinetics, thermoplasticity, and precipitation control of nano sized Cu rich phase, etc., in order to help better understanding of this novel type of Cu bearing MIC resistant pipeline steels, guide the future production practice, and promote the application and development of Cu bearing pipeline steels.
