The corrosion behaviors of super 13Cr tubing steels were investigated by immersion corrosion test in NaCl solution from 20 ℃ to 80 ℃.The corrosion rate,corrosion morphologies,corrosion products and electric characteristics of surface films were analyzed by scanning electron microscopy(SEM),energy dispersive analysis(EDS),X-ray Diffraction(XRD),weight loss,polarization and electrochemical impedance spectroscopy(EIS).The results shows that super 13Cr tubing steels has better general corrosion resistance prope...
