| Abstract: | This paper introduces the quick developments of 600℃USC power plants and its requirements on high temperature materials in China under the progress of world coal-fired power plants.Three newly developed austenitic heat-resistant steels mainly used as the key components of superheat/reheater tubes are analyzed in terms of chemical composition,microstructure and properties.The characteristics and present research of austenitic heat-resistant steels used in USC power plant are discussed.With the further increased value of steam parameters of USC power plants,the new development of austenitic heat-resistant steels to meet high temperature property requirement has been also suggested. |
