Corrosion of Fe-2.25Cr-1.6W-0.1Mo Steels in Na₂SO₄ Salts at 800 and 900°C

Abstract:

The ASTM T23 steel with a composition of Fe-2.25Cr-1.6W-0.1Mo in wt.% was corroded in the Na₂SO₄ salt at 800 and at 900°C, and its corrosion behavior was studied. It formed thick, porous oxide scales that consisted primarily of outer Fe-rich oxides and inner (Fe, Cr)-rich oxides. The corrosion of the T23 steel progressed mainly via oxidation.
