S355NL steel phaj yog weldable nplua-grained structural steel ua nyob rau hauv normalized los yog normalized dov lub xeev ua raws li EN10025 tus qauv. Lub S355NL steel phaj pronounced raws li S txhais tau hais tias cov European txheem qauv hlau yog pronounced li S. 355 txhais tau hais tias lub zog tawm los ntawm cov hlau phaj tsis tsawg tshaj li 355MPa. Nyeem li 355, N nyeem raws li N yog tus txheej txheem xa khoom ntawm cov phaj hlau, N sawv cev rau kev ua haujlwm zoo lossis ua kom lub cev ua haujlwm zoo li qub, lub sijhawm xa khoom yog normalizing dov, L nyeem raws li L txhais tau hais tias qhov kub ntawm cov hlau phaj tsis tsawg dua {{ 7}} degrees Qhov ntsuas kub qis tshaj plaws, S355NL steel phaj muaj qee yam hnav tsis kam thiab hardness, thiab S355NL muaj me me txiav deformation thiab yooj yim rau vuam. Nws yog cov khoom siv vuam siv feem ntau rau cov khoom siv thiab tuaj yeem siv los txiav cov tailor-welded flanges, hnav-tiv taus qhov chaw thiab cov khoom tshwj xeeb.
S355NL steel phaj Z-kev taw qhia kev ua tau zoo: Z-kev taw qhia kev ua tau zoo yog cov thickness kev coj ua ntawm steel phaj. Z15, Z25, thiab Z35 yog qhov sib txawv ntawm Z-kev taw qhia kev ua tau zoo (tseem los ntawm qis mus rau siab). Z-kev taw qhia kev ua tau zoo tseem hu ua anti-lamellar kua muag hlau. , steel phaj txoj kev sim thiab kev sim ua tau tsuas yog siv cov thickness coj mus kuaj cov qauv tensile cov ntsiab lus thiab cov ntsiab lus ntawm cov hlau phaj los txiav txim seb cov hlau phaj puas tau raws li Z-kev coj ua qauv.
S355NL steel phaj siv: S355NL steel phaj feem ntau yog siv rau kev txiav cov khoom loj, flanges, loj tailor-welded flanges, cua zog tej yaam num, dej txuag thiab hydropower, engineering machinery, mining machinery, chaw nres nkoj machinery, shipbuilding, mining machinery qhov chaw, thiab lwm yam .
