【Abstract】 CO₂ corrosion behaviors of 1Cr13,2Cr13 and HP13Cr stainless steels were studied in the simulated high pressure and high temperature CO₂ corrosion environment.The results showed that the uniform corrosion rates of the three kinds of materials were 2Cr13>1Cr13>HP13Cr ,the peak all in 150 ℃.They were also increased with the increase of CO₂ partial pressure.Flow velocity and Cl^- concentration when it was within 10×10^-6～10 000×10^-6.When the concentration of Cl^- concentration exceeded 10 000×10^-6,the uniform corrosion rate. Was reduced with the increasee of it.更多还原
