S355j2 galvanized h nqaj hlau profile
Galvanized S3555J2 H-ntu yog lub siab-muaj zog tsawg-alloy qauv hlau nyob rau hauv raws li en {}, tsim rau cov khoom siv thauj khoom ua kom zoo.
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab ntawm S355j2 Beams
Yield zog (R): 355 mpa (tuab tsawg dua lossis sib npaug rau 16 hli); 345 MPA (16-40 mm); 335 MPA (40-63 hli).
Tensile Lub Zog (RM): 470-630 MPa.
Elongation (a): ntau dua los yog sib npaug rau 22% (tuab tsawg dua lossis sib npaug nrog 40 mm).
Kev Cuam Tshuam Cov Khoom Siv: Loj dua lossis sib npaug rau 27 J ntawm -20 degree.
Qoob qaug zog: Haum rau kev thauj khoom zoo (piv txwv li choj, cranes).
Galvanizing cov txheej txheem rau s355j2 h-nqaj:The steel profile is immersed in molten zinc (450-460 degree ) to form a 70-100 µm coating, which enhances corrosion resistance in humid or marine environments; Cov lus qhuab qhia tom qab galvanizing (piv txwv li passiveation) txhim kho adhesion thiab nto tas.
Qhov zoo ntawm S35555j2 galvanized h-nqaj tsim los ntawm gnee
Corrosion Kuj: Lub Zinc Txheej Muaj peev xwm txuas ntxiv cov kev pabcuam lub neej nyob rau ib puag ncig hnyav.
Lub zog-hnyav piv: txo cov nqi ntawm cov khoom siv thaum khaws cov qauv kev ntseeg.
Daim ntawv pov thawj: CE khij thiab en 10025-2 Ua raws li cov qauv hauv ntiaj teb zoo.
