In the present study，P110 tubing steel was studied with chemical composition as listed in Table 1.It can be seen from Fig.1 that the microstructure of P110 tubing steel is homogeneous，comprising tempered sorbite，and has no obvious rolling texture features.Samples with dimensions of40 mm×10 mm×4 mm for immersion corrosion tests and coupons with dimensions of 10 mm×10 mm×4 mm for electrochemical tests were prepared from P110 tubes.All samples were ground by abrasive silicon carbide paper to1000#and cleaned in acetone for 5 min ultrasonically.
