简要介绍一种性能优异的过热器管材用铁基高温合金GH2984的成分设计与性能. 该合金的特点是不含贵重元素Co, 且有32%-34% 的Fe, 因而成本低廉。分析了这一合金制作舰船用和超级超临界发电锅炉用过热器的优越性. 舰船实际应用结果表明, GH2984合金是一种性能优异的舰船用过热器管材合金. 该合金也是超级超临界燃煤电站锅炉用过热器和再热器管材用钢的重要候选材料.
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
