Linear-Parabolic kinetics and multilayer oxide scales with voids were found for both alloys. Based on the experimental results, AISI 304L presented higher oxidation resistance and higher activation energy. Zircaloy-4 kinetic results were used for validation and performance comparison. In severe accidents conditions, stainless steel might lead to a faster hydrogen production comparing to Zircaloy.1-7openAccessoxidationstainless steelshydrogenstainless steel-348stainless steel-304lzircaloy 4chemical compositionArtigo de periódico62310.1590/1980-5373-MR-2020-037316.6750.25
