Abstract: A method for inhibiting corrosion under insulation (CUI) on the exterior of a structure, e.g., pipelines, piping, vessels and tanks, is provided. The method involves providing a structure that is at least partially formed from a corrosion resistant carbon steel (CRCS) composition. The CRCS composition includes corrosion resistance alloying additions in the amount of 0.1 weight percent to 9 weight percent. At least one alloying addition has a low free energy of formation for its oxide and/or hydroxide, e.g., vanadium and/or titanium. A corrosion inhibited structure that includes a structure at least partially formed from a corrosion resistant carbon steel (CRCS) composition, and insulation positioned around at least a portion of the structure.
