Abstract Scope Lead and lead-based alloys are under consideration as working fluids for energy-related applications, such as advanced nuclear reactors, concentrated solar power and hydrogen production. However, their compatibility with Al-free structural steels (ferritic-martensitic and austenitic) causes considerable concerns. Alumina-forming austenitic steels, exhibiting high-temperature creep strength and oxidation resistance combined with a relatively low price, have a great potential to be used as structural materials for advanced energy systems. Therefore, model steels of FeCrAlNiX system (X: C, N, Nb, Y), were designed to form a protective alumina scale during exposure to oxygen-containing molten lead and to preserve the austenitic structure. The corrosion experiments were performed for up to 5000h, at 550-750°C temperature range in stagnant molten lead. The experimental results are presented and discussed in this communication.
