Aim of the study is the adaptation of a modeling concept to internal oxidation during steam oxidation using the cellular automata (CA) approach. The CA system is implemented for the alloys that undergo most severe corrosion degradation. In this work, steam oxidation process for two solid‐solution strengthened alloys; Haynes® 230®, 617 alloy, two γ ’‐strengthened alloys; 263 and Haynes® 282®, and three austenitic steels rich in Cr: 309S, 310S, and HR3C, are analyzed. The study shows that the exposure in steam environment leads to a thin oxide scale formation consisting mainly Cr 2 O 3 and MnCr 2 O 4 spinel type oxide, except alloy 617, where NiCr 2 O 4 spinel is observed. The modeling studies of internal oxidation development are applied to γ ’‐strengthened alloys, Haynes® 282® and alloy 263, and are shown to be in good agreement with the experimentally observed pronounced internal oxidation attack.
