英文摘要	A superheater tube superalloy GH2984 with excellent properties had been successfully developed, which does not contains expensive element Co but has 32%-36% Fe, so it has low cost. In this paper, the characteristics of GH2984, including the chemical composition, mechanical and chemical properties, the microstructure stability after long-time thermal exposure and the processing property at hot and cold conditions have been introduced briefly. Then the superiority of this alloy used in ship boiler and ultra-supercritical coal-fired boiler as superheater was analyzed. The results from practical application to the ship boilers show that the GH2984 superalloy is suitable to the ship boiler superheater tube material, and the alloy also is very important candidate of a superheater and reheater materials in the ultra-supercritical steam boilers.
