Abstract The electrochemical performance of a new 6% Cr steel was investigated intensively by means of a broad variety of electrochemical methods (EIS, CV and CPP) and surface characterization techniques (AFM, XPS, EPMA and ESEM/EDS) in simulated concrete pore solution (SCPS) with chlorides. Improved corrosion resistance of 6% Cr steel in SCPS was established by the protective passive film, the high pitting corrosion resistance as well as the compact rust layer, which may shed light on the design of corrosion-resistant reinforcing steels with enhanced corrosion resistance throughout the service life of reinforced concrete structures.
