S275NL steel phaj yog European tus qauv qauv qis alloy steel phaj. "S": qhia tias nws yog European tus qauv qauv steel; "275": qhia tias lub thickness ntawm no steel 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 N": qhia tias qhov kub thiab txias tsis tsawg dua -20 degree thaum qhov cuam tshuam ua haujlwm tau teev tus nqi yam tsawg kawg nkaus; "L": qhia tias qhov cuam tshuam kub ntawm S275NL -50 degree .
S275NL steel phaj tus me nyuam lub xeev: normalized steel phaj. Lub xeev tus me nyuam kuj tuaj yeem raug teev raws li kev xav tau.
