Corrosion mechanism of the drum in a boiler was studied by macroscopic observation, hardness and thickness tests, and corrosion products analysis. The damage surface displays a large unsmooth corrosion area with decreased hardness. The materials failed due to dissolved oxygen in feed water and the corrosion process was suggested to be divided into four stages. The formation of the morphologies was also described.
