  • Cu Of the many alloying elements, only copper is advantageous against hydrogen induced cracking (HIC) properties. Adding a certain amount of copper to the pipeline steel, the hydrogen induced crack sensitivity is significantly reduced, mainly copper promotes blunt The formation of the film reduces the intrusion of hydrogen and hinders the formation of hydrogen induced cracks. In the technical solution of the present invention, the resistance to hydrogen induced cracking (HIC) is improved by adding a certain amount of copper. Therefore, the Cu content is controlled to be 0.125 to 0.135 wt%.
  • Mn The effect of Mn on the hydrogen induced cracking resistance of pipeline steel is mainly reflected in the influence of Mn on the phase transformation process of strip steel.
  • the Mn content exceeds 1.0 wt%, the sensitivity of hydrogen induced cracking (HIC) increases. Therefore, in the technical solution of the present invention, the Mn content is set to 0.75 to 0.95 wt%.
