... alloy C-276) were placed directly in the hot gas stream, containing HCl and Cl2, for in situ testing. Results of this investigation showed that nickel-chromium corrosion-resistant alloys, such as Inconel 600, Inconel 625, and Inco alloy C-276, performed well in this environment. Laboratory testing...

... environments accelerates sulfidation attack ( Ref 24 ). Hatfield ( Ref 25 ) observed that sulfidation of Ni-18Cr and Ni-28Cr alloys was initiated by the formation of NiS, which prevented the continuous formation of Cr 2 O 3 at NiS sites. The higher chromium content of the Ni-28Cr alloy reduced the substrate...
