S355N: Normalized rau kev nplua -grain microstructure, txhim kho toughness rau xav tau welds. Preheating feem ntau tsis xav tau rau<20 mm; optional for thicker plates (100-150°C); PWHT optional (550-650°C). CEV ≤0.43%.
S355J2+N: Normalized, tsis yog{2}} hlau alloy nrog kev ua haujlwm yooj yim; weldability zoo heev vim qis CEV (tsawg dua lossis sib npaug li 0.45%). Preheating tsis tshua xav tau rau cov phaj nyias.
Consumables: Ob leeg siv ER70S-6 (GMAW) thiab EM12K flux nrog EH14 hlau (SAW). S355N's microalloying ua kom zoo dua toughness hauv welds, zoo ib yam li en 10025 3 s275n normalized structural steel phaj.
Daim ntawv thov
S355N: Siv nyob rau hauv siab - cov qauv thauj khoom xws li txuas hniav, cranes, thiab cov tshuab hnyav hauv cov huab cua nruab nrab, siv nws cov nplua - cov qauv nplej thiab txhim kho toughness.
S355J2+N: Siv dav hauv kev tsim kho, vaj tse, thiab kev tsim kho vaj tse, qhov twg tus nqi- ua tau zoo thiab tus qauv toughness txaus.
S355N yog qhov zoo dua rau cov ntawv thov tseem ceeb uas xav tau lub zog zoo dua, thaum S355J2+N haum rau tus nqi- cov haujlwm tseem ceeb. Rau cov huab cua txias, xav txog en 10025 3 s355nl normalized structural steel phaj.

GNEE tau pab cov neeg siv khoom hauv ntau dua 50 lub teb chaws (North America, Europe, Southeast Asia, Middle East, thiab lwm yam) thiab tau txais kev nplua nuj nyob rau hauv cov nqe lus lag luam thoob ntiaj teb (FOB, CIF, EXW) thiab cov kev cai hauv zos. Peb cov kev sib txuas lus tau zoo (Lus Askiv, Mev, Arabic kev txhawb nqa) thiab cov txheej txheem kev lag luam pob tshab ua rau kev sib koom tes zoo thiab tsis muaj teeb meem - dawb.
