Abstract In order to meet the requirements of superheater and reheater boilers in 630-650 ℃ ultra-supercritical power plants,The C-HRA-5 stainless steel seamless steel pipe was prepared according to the process of "EAF+AOD (or VIM+ESR)+diameter forging+extrusion+cold rolling" through the technical research of composition design,smelting,cold and hot deformation and heat treatment and breaking through the bottleneck of key technology. The products are characterized by precise chemical composition control,low volume percent of non-metallic inclusions,pure steel,good surface quality,uniform structure and excellent performance. Its chemical composition,grain size,micro-structure,mechanical properties at room temperature,high temperature tensile properties,high temperature durability and other performance indicators meet the requirements of ASME SA-213 standard,and its steam oxidation resistance and welding performance are excellent. Its physical quality has reached the international advanced level,and has been evaluated by Shanghai Boiler Works,Ltd,Dongfang Boiler Group Co.,Ltd.,Harbin Boiler Co.,Ltd.,Shanghai Power Equipment Research Institute and CISRI. The product has been appraised and certified by the National Technical Committee for Standardization of Boiler and Pressure Vessel,and has taken the lead in formulating relevant group standards. It can be used in superheater,reheater and other parts of ultra (ultra) critical boiler,as well as pressure structure parts under similar conditions.

Key words： ultra supercritical boiler heat resistant steel seamless pipe
