EN 10025-3 S355N steel phaj yog nruab nrab- lub zog, nplua-grained steel qauv tsim los rau kev siv weldable hauv kev tsim kho thiab engineering. Nws ua raws li European tus qauv EN 10025-3, uas qhia meej txog kev xa khoom rau cov khoom siv zoo li qub / zoo li qub dov weldable nplua nplej cov qauv hlau. Cov xwm txheej tus me nyuam yog normalized los yog normalized dov, ua kom lub microstructure refined rau txhim kho toughness thiab sib xws.

FAQ
Puas yog EN 10025-3 S355N steel zoo rau vuam?
Yog; CEV Tsawg dua lossis sib npaug li 0.43% tso cai ncaj qha arc vuam yam tsis muaj kev pab tshwj xeeb.
EN 10025-3 S355N yuav siv tau li cas?
Los ntawm -20℃mus rau +500 degree, nrog toughness ntawv pov thawj ntawm -20 degree; siv S355NL rau txias txias.
TS EN 10025-3 S355N puas yuav tsum tau preheating thaum vuam?
Tsis pub tsawg dua lossis sib npaug li 20 mm; 100-150℃pom zoo rau cov phaj tuab.
EN 10025-3 S355N sib npaug rau ASTM A572?
Piv rau A572 Qib 60 (yield ~ 415 MPa sib npaug), tab sis EN 10025-3 S355N's normalization txhim kho toughness; tsis zoo ib yam.
Qhov siab tshaj plaws thickness rau EN 10025-3 S355N yog dab tsi?
Txog li 250 hli, nrog cov khoom hloov kho kom muaj kev ua tau zoo.
EN 10025-3 S355N tuaj yeem siv rau hauv kev tsim choj?
Yog; haum rau cov ntsiab lus thib ob hauv thaj chaw sov vim muaj zog thiab -20℃toughness.
