The effects of Y,Ce and La on the sulfidation of alloy Fe-25Cr-40Ni have been investigated. The sulfidation rate of the alloys with RE more than 0.1 wt-% is lower than that of the base alloy.The addition of Y is more effective than La and Ce in lowering the sulfidation rate. Based on the analyses of the structure and composition of the sulfide seales,the sulfidation mechanism of the alloys with RE has been proposed.
