摘要：
The corrosion properties of low alloy steel immersed in NaCl solution containing H2S and CO2 are investigated. The study is carried out using electrochemical measuring method. Scanning electron microscopy is used to observe the corrosion surface morphology, and the compositions are analyzed by energy-dispersive spectroscopy. The results show that the low alloy steel with more fine grain shows good corrosion resistance, it has lower corrosion current density and bigger the polarization resistance. The relationship of rolling parameters, grain size, electrochemical parameters and corrosion surface morphology are discussed.
