A number of low chromium content steels have been developed with the intent of providing increased corrosion resistance in CO2 containing oil and gas environments. The chromium content can be 0.5% 1% or 3% in these alloys. It is however probable that these alloys would be used in combination with chemical corrosion inhibition and there is little data on how inhibitors would interact with this class of alloys. Experience with low nickel content alloys indicates that alloy additions can adversely affect inhibitor performance and it is thus of interest to examine the effect of chromium additions. This paper reports a laboratory study into the effectiveness of corrosion inhibitors for corrosion prevention of low chromium content alloys. The study concentrates upon alloys with up to 1% Cr. Techniques used include static and dynamic tests monitored by electrochemical methods such as linear polarisation resistance (LPR) and electrochemical impedance spectroscopy (EIS).
