Microstructural investigation of the nodular corrosion of 304NG stainless steel in supercritical water

Abstract:

304NG stainless steel was exposed to deaerated 600 °C supercritical water for 300 h. The thin Cr-rich oxide film and corrosion nodules were characterized in detail by cutting edge techniques. The results show that the formation of MnCr2O4 is an important factor that deteriorates the protectiveness of the Cr-rich thin oxide film. Reaction zones ahead of the inner oxide are observed. The reaction zones are composed of oxide particles and remaining metal, indicating the occurrence of internal ox...
