Abstract The authors of the paper reviewed and summarized the investigation in laboratories, pilot trials and industrial implementation of S30432 boiler steel tubes used for fossil fired ultra super critical (USC) power plants in China in the past decade, with the emphasis on the technical breakthrough of the determination of chemistry optimization and the best fit heat treatment during production. The advancement of industrial production of S30432 steel tubes and its expected application in China was also included in the present paper. The obtained results have shown that the steel and boiler makers of China have been able to successfully manufacture S30432 boiler steel tubes used to build USC power plants, the technology is mature, and the supplying capability has gradually achieved
