This work aims to describe the corrosion behavior of austenitic steels 316L and 15-15Ti under the nominal conditions of the ALFRED reactor phase II operation. Specimens of 316L and 15-15Ti stainless steel were exposed to flowing lead. Post-test microscopic analyses revealed a possible mechanism of long-term susceptibility to localized solution-based attack. The corrosion of both austenitic steels was low, a thin oxide layer (80–240 nm) thin was formed, and a large-scale dissolution attack was not observed. The surface was mostly covered by a protective thin spinel film with variable Cr, Fe, and Mn ratios.
