API 5L X65 steel yeeb nkab yog siab - lub zog kav hlau uas tsim los ntawm microalloyed tswj dov thiab txias (TMCP) txheej txheem. Hauv nws lub npe, "X65" sawv cev rau qhov tsawg kawg nkaus tawm lub zog ntawm 65ksi (kwv yees li 448MPa). Nws cov khoom siv zoo heev thiab kev tiv thaiv corrosion ua kom nws muaj kev ruaj ntseg hauv ntau qhov chaw hnyav, ua rau nws yog ib qho khoom siv tsis tseem ceeb hauv ntau qhov chaw lag luam.
