| Abstract: | Literature researches and analyses were conducted on a new kind of w(Cr)=15%(15%Cr)ferritic heat-resistant steel with the purpose of finding out the design ideas,strengthening mechanism,microstructure and properties,and the research status.Results show that the 15%Cr ferritic heat-resistant steel has better microstructure stability,with creep rupture strength and steam oxidation resistance higher than traditional w(Cr)=9%12%ferritic steels,which may be taken as a potential steel for high-temperature components of 650℃ultra-supercritical thermal power plants. |

| Keywords: | ferritic heat-resistant steel ultra-supercritical unit creep rupture strength |
