Corrosion of modified 9Cr–1Mo steel (P91) and Indian Reduced Activation Ferritic Martensitic Steel (IN-RAFMS) was studied in static lead–17 atom% lithium eutectic for 355 h at 773 K. Exposure to molten Pb–17Li led to loss of weight in P91 material whereas IN-RAFMS gained weight which was possibly due to longer incubation period and post-exposure surface oxidation. Depletion of Fe and Cr occurred from a thin surface layer in both P91 and IN-RAFMS although higher oxygen buildup on the surface of IN-RAFMS justified its weight gain.
