In this paper, the development process of SS105 grade rare earth microalloying seamless tube for drill pipe body resistant to H2S stress corrosion is introduced. The designs of its chemical composition system and key production process are carried out according to the requirements of technical specification of a company and the API Spec 5DP 2020 Drill Pipe Specification as well as trial production of the product is carried out at the same time. The quality of continuous casting billet as well as chemical compositions, mechanical performances, metallographic structure and non-metallic inclusions of finished product are tested, all the indexes could meet design requirements. The effects of rare earth Ce on resistance to H2S stress corrosion of SS105 grade seamless tube for drill pipe body are evaluated based on its service environment of the oil and gas drilling environment with high content of H2S and low temperature. The results showed that the resistance to H2S stress corrosion of the product was significantly improved after add rare earth into it.
