S275N belongs rau European txheem carbon structural steel phaj, "S": qhia tias nws yog European txheem steel qauv; "275": qhia tias lub thickness ntawm cov hlau phaj yog tsawg dua los yog sib npaug rau 16 hli, thiab lub zog tawm los yog tsawg kawg yog 275Mpa; "N": qhia tias qhov kub thiab txias tsis tsawg dua -20 degree thaum qhov tsawg kawg nkaus tus nqi ntawm kev cuam tshuam kev ua haujlwm; "L": qhia tias qhov cuam tshuam kub ntawm S275NL yog -50 degree .
S275N steel phaj siv cov qauv: kev ua raws li European tus qauv EN10025 tus qauv.
S275N steel phaj tus me nyuam raws li txoj cai: kub dov, tswj dov, normalized, normalized dov lub xeev tus me nyuam, lub steel phaj yuav tsum tau txiav ntug kev xa khoom (tshwj xeeb tus me nyuam yuav tsum tau sau tseg).
