The oxide metallurgy is used in the fabrication of X80 pipeline steel. The mechanical properties of X80 steel at different tempering temperatures are studied by offline heat treatment process. The hydrogen‐induced cracking (HIC) susceptibility of X80 steel with optimal mechanical properties is studied. The results show that the optimal combinations of mechanical properties are obtained for the X80 pipeline steel under the heat treatment conditions of water quenched at 900 °C and tempered at 630 °C. The yield strength of the X80 steel is 569 MPa and the impact energy is higher than 300 J at −40 °C. After deoxidation by Ti and Zr, the average size of inclusions in X80 steel is 0.23 μm. Among them, the typical spherical composite inclusions are TiOX–Al2O3–ZrO2–MnS, combined with the fine (Nb, V, Ti)C and the formation of Cu2S and Cr2O3 protective layers. X80 steel has excellent HIC resistance. [ABSTRACT FROM AUTHOR] |
