L245N yog ib txoj hlua ncaj nraim welded yeeb nkab, qhov L txhais tau hais tias kab, 245 txhais tau tias nws lub zog tawm los yog ntau dua lossis sib npaug rau 245MPa, lub zog tensile siab dua lossis sib npaug rau 415MPa, thiab elongation yog ntau dua lossis sib npaug rau 21. }%. Cov yeeb nkab steel yeeb nkab no zoo heev nyob rau hauv cov nqe lus ntawm vuam kev ua tau zoo, yog li nws yog feem ntau siv nyob rau hauv kev thauj mus los ntawm cov roj los yog natural gas. L245N ncaj seam steel yeeb nkab belongs rau pipeline steel series, thiab cov qauv siv yog cov txheej txheem tshwj xeeb ntawm GB / T9711-2017. Tsis tas li ntawd, L245N seamless yeeb nkab kuj yog ib lub teb chaws cov khoom siv rau cov kav dej siv hauv kev lag luam roj thiab roj tsheb thauj mus los. Cov khoom siv hauv tebchaws suav nrog L290N, L360N, L390N, L415N, thiab lwm yam.
