Through the research of carbon dioxide corrosion mechanism, combined with the influence of chemical elements on the microstructure, mechanical properties and corrosion resistance of steel, economical special tubing steel and its components for CO2 corrosion resistance are designed. Through the CCT curve measurement, hardenability testing, mechanical property testing after heat treatment and detection analysis of carbon dioxide corrosion resistance on test steel, the results show that the hardenability and mechanical properties of the designed steel can meet the design requirements, but there is a certain gap between the corrosion resistance and the design index, and there is optimization space in composition design. On this basis, the steel grade and chemical composition of economical special tubing steel for carbon dioxide corrosion resistant are optimized. It can be seen from the experimental results that the anti-corrosion index of optimized steel grade after quenching and tempering treatment can meet the design requirements.
