Pressurized combined oxidation and corrosion tests
Steam inside the tube, flue gas and ash deposit at the outside. Temperature 612 to 671°C. The steamside oxide layer remains very thin, whereas the corrosion layer on the flue gas side is rather thick. At 671°C the penetration of sulfur leads to an inacceptable corrosion behavior. Nevertheless the oxidation and corrosion properties are better than those of 9%Cr steels.
