Corrosion is an important mode of degradation and failure for iron alloys used in oil and gas pipelines. Pitting corrosion is a particular type of corrosion that is not well-understood and can play in important role in material failure. Research has shown that areas of increased plastic strain develop within pits which may promote crack initiation and material failure. This paper aims to analyze the impact of increased plastic strain on the general corrosion rate of X65 pipeline steel. Samples of X65 steel cold-rolled to 0%, 5%, 10%, 15% and 20% plastic deformation were tested using linear polarization methods in a 10% NaCl, CO2 saturated environment. It was found that there was no impact from the amount of plastic strain on the general corrosion rate of the X65 steel.
