Crevice corrosion affects the integrity of stainless steels used in oil and gas components exposed to seawater. In this work, the crevice corrosion resistance of a 22-Cr duplex and a 25-Cr super duplex stainless steels (UNS S31803 and UNS S32750, respectively) were investigated.

A refinery in the U.S. Gulf Coast had been using carbon steel tubes in two crude unit overhead condensers that suffered severe corrosion leading to premature failure after just 6 months in service. The metallurgy of the tube bundles was later upgraded to super duplex, UNS S32750, and hyper duplex stainless steel (DSS), S32707, which extended the service life to 12 months and two years, respectively. Failure analysis of the DSS indicated that the corrosion started as under-deposit corrosion. Selective corrosion occurred, where the ferrite phase suffered a preferential corrosion attack. Super Austenitic Alloy 35, UNS N08935, was recommended as an economical alternative to nickel Alloys 625 (UNS N0625 and C-276 (UNS N10276). Material selection and life-cycle cost analysis helped the end user select the super austenitic Alloy as the material of choice for the upgrade. The bundles have been in service for more than two years. This paper evaluates the materials selection process, fabrication cost, and life cycle cost analysis of the different Alloys used in these bundles since the first carbon steel upgrade through the present time.

Study to assess pitting corrosion resistance of 316L ASS (UNS S31603) and 25%Cr SDSS (UNS S32750) in salt solutions containing dissolved oxygen(DO). The DO levels examined were: 20, 50, and 100ppb, and the concentration of chloride ions were up to 152g/L Cl-, at 50 and 60°C. The results are reported herein.
