Abstract Scope With renewed interest in Pb-cooled reactors, new compositions of alumina-forming austenitic (AFA) steels were selected for evaluation in static Pb at 500-800C and flowing Pb with a peak temperature of 650C without pre-oxidation. Two general AFA classes were investigated, ~14Cr-(8-12)Ni-5Mn-2.3Al and 16Cr-25Ni-2Mn-3.8Al and compared to type 316H stainless steel. As expected, specimen mass loss increased with temperature after 1000 h exposures to Pb in sealed Mo capsules. The low Ni AFA samples showed lower mass loss at lower temperatures and the high Ni AFA showed less mass loss at 700C, presumably due to easier alumina formation. Additional capsule experiments were conducted with Zr foil to getter oxygen, which generally reduced mass loss. Based on the capsule experiments, two AFA alloy compositions with 12Ni and 25Ni were selected for exposure in a thermal convection loop (TCL) constructed from pre-oxidized FeCrAlMo tubing. The TCL is assembled and results will be presented.
