Abstract According to the characteristics of the environment for the use of ultra-supercritical thermal power units key stainless steel, the principle of the TISCO heat-resistant steel TP310HCbN design, strengthening mechanisms, technical measures and the production process was set forth. The microstructure, weld and precipitates were researched by using TEM and EDS analysis test, and the conventional mechanical properties, high-temperature tensile properties and creep and rupture mechanical were investigated. The development of TP310HCbN heat-resistant seamless steel pipe has uniform organization and comprehensive performance, and the products has entered the stage of mass production.
