Txoj kev loj hlob ntawm cov raj xa dej engineering yog cov yeeb nkab loj txoj kab uas hla, siab-siab nplua nuj roj tsheb thauj mus los, siab txias thiab corrosive kev pab cuam ib puag ncig, thiab tuab-walled submarine pipelines. Yog li ntawd, niaj hnub pipeline steel yuav tsum muaj lub zog siab, tsis tshua muaj Bauschinger nyhuv, siab toughness thiab tsis kam mus nkig tawg, tsis tshua muaj vuam cov ntsiab lus thiab zoo weldability, raws li zoo raws li tsis kam mus rau HIC thiab H2S corrosion.
