Yield Strength: Ob leeg muab 355 MPa, zoo tagnrho rau nruab nrab -load qauv.
Tensile Strength: Zoo tib yam ntau yam (470-630 MPa) ua kom zoo dua qub.
Elongation: Ob leeg muab ntau dua lossis sib npaug li 22%, txhawb kev tsim qauv.
Impact Toughness: Ob leeg muab ntau dua lossis sib npaug rau 27 J ntawm -20 degree, haum rau cov huab cua nruab nrab.
Hardness: S355N qhov nyuaj dua me ntsis (150-190 HB vs 140-180 HB) qhia txog nws cov qauv zoo.
Thickness: S355N txog 200 hli, S355J2+N txog 400 hli, muab ntau dua thickness versatility rau S355J2+N, zoo ib yam li en 10025 3 s355n normalized structural steel phaj.
Processing thiab Fabrication
S355N: Normalized rau 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 - alloy steel 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.
Cov khoom siv: 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.
GNEE tau ua haujlwm rau 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 khoom lag luam 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.
