Produced fluids from deep, hot gas wells are often accompanied by low molecular weight organic acids in Australia, Japan in addition to Southeast Asia regions. Influences of organic acids on corrosion performances of corrosion resistant alloys (CRAs) are evaluated in high temperature sweet environments. It is considered that organic acids, such as acetic acid, have some adverse effects on the protectiveness of passive films (oxides and/or sulfides), in addition to the pH lowering effect. In this present study, influences of acetic acid on localized corrosion performances of Supermartensitic 13Cr, 15Cr, and 22Cr Duplex stainless steels (SS) have been investigated using electrochemical techniques, weight-loss measurements and slow strain rate tests in sweet environments at ambient temperature and 180o C.

Key words: acetic acid, CO2 corrosion, high temperature, polarization curve, weight-loss measurements, slow strain rate test, Supermartensitic stainless steel
