The most serious problem for high-efficiency municipal solid wastes power generation is hot corrosion of superheater tubes. Indirectly superheating system using a high temperature air heater enables high-efficiency power generation without hot corrosion of superheater tubes. The pipe materials for a high temperature air heater are needed corrosion resistance in high" temperature chlorine contain gases. In this study, the pipe materials were investigated form the viewpoint of corrosion resistance, high temperature strength and so on. And then, it was found that Ni base cast alloys maybe considered as one of the promising materials for the pipe element and Al addition to the alloys improves corrosion resistance in high temperature chlorine containing gas. From these results, Al containing Ni base cast alloys was developed.
