Abstract The aim of the work has been to study the corrosion resistance of a new low alloyed experimental FeCrAl steel, with the potential use as corrosion barrier in high temperature lead based energy applications. The exposures were conducted in liquid lead at 800 °C and 900 °C, with controlled oxygen environment, for up to 1760 h. The results demonstrate that the new experimental alloy had formed a protective oxide in both exposures, with no indications of lead penetration. The alloy showed better corrosion properties than that of the reference materials: Kanthal APM™, Kanthal APMT™ and AISI 316L. This indicates that the ductile Fe–10Cr–4Al-RE steel can be used as a corrosion barrier in liquid lead based clean energy applications, operating at very high temperatures.
