... steel UNS S31010 and 25Cr Super Duplex stainless steel (UNS S39274) in brines at various chloride concentrations. For 25Cr Super Duplex, CCT were determined based upon ASTM G150 and ASTM G192 standards. Comparative tests were also performed to determine repassivation potential (E_rp) using...

.... Such unintended exposure to oxygen is related to poor maintenance or improper preservation and would normally require replacement of equipment. Further use of such pitted components can be considered but requires re-assessment of the pre-corroded material. Open-circuit Potential (OCP) and repassivation potentials...

...%Cr stainless steel localized corrosion seawater dissolved oxygen injection well repassivation INTRODUCTION Oil & Gas companies sometimes explores the possibility of converting producing wells to a water injectors. The suitability and compatibility of the used alloys therefore needs...

...Pitting corrosion stainless steel concrete crack repassivation Abstract At early stages, reinforced concrete structures exposed to chloride ions are prone to pitting corrosion. In carbon steel reinforcement, pitting is expected to quickly transition into widespread corrosion damage. However...

... then be quantified using a ‘chloride susceptibility index’. In this paper the scientific approach is presented and applied to provide insights regarding the role of composition and environment on the localized corrosion of steel and nickel-based alloys. Corrosion Modeling Repassivation Localized corrosion...
