dc.description.abstract	The features of metal dusting in extremely low nickel austenitic stainless steel (18Cr-21Mn-0.65N-Fe) were studied in syngas environment (75% H2 and 25 %CO) at 400-700 °C, under cyclic exposure for 300 h. Carbon corrosion occurred at 400-500 °C, however, at 600-700 °C, oxidation of Mn and formation of Mn-Cr-O spinels significantly reduced the carbon attack. The surface and cross section of the exposed coupons were examined by XRD, SEM(EDS) and EPMA. Metal dusting resulted in formation of very few corrosion pits of the size 2-7 μm and epitaxial growth of carbon nanotubes on the surface exposed at 400-500 °C. © 2020 Elsevier Ltd	en_US
