Overview of the Research on Candidate Materials for Advanced Ultra-supercritical Boiler Tubes

摘要：

　　The drive to increase the efficiency of pulverized coal-fired power plants has led to raised steam conditions with operating temperature and pressure of 700℃/35MPa.A stress rupture life of 100000 hours at 750℃/100MPa stress as well as the metal loss of less than 2mm in 200000 hours are required for these advanced ultra-supercritical boiler tubes.This paper summarized the research on the four candidate superalloys,i.e.Inconel740H、617B、HR6W and Sanicro25 at domestic and foreign.
