UB 1 {0 16x305x 249 1016 x305x272 s355j0 h nqaj tshooj
S355J {{{1} h steel profile yog lub zog loj ntawm ntau dua lossis sib npaug thiab muaj zog tshaj lossis sib npaug rau 355mpa. Nws muaj cov tensile zoo heev, compressive thiab bendant tsis kam.
Tshuaj lom neeg muaj pes tsawg leeg ntawm s355j {1}} h bar seem
Cov ntsiab lus carbon (c) {{{{{{{{{{}}}}}}. 230%, sulfur (s) tsawg dua los yog sib npaug 0.025%. Cov tub qhe uas tsawg thiab phosphorus tsim txhim kho kev ua kom nruj thiab vuam kev ua si.
Cov yam ntxwv ntawm S355J 0 hlau h profile: nws muaj qhov zoo weldability, haum qhov tseeb ntawm qhov chaw thiab ruaj khov ib puag ncig cov ntawv thov.

Cov txheej txheem ntau lawm ntawm S355J {1}} h hom nqaj
KUB Rolling Txheej Txheem: Txais kub doling sib sau ua cov thev naus laus zis, kev ua yeeb yam yooj yim dua, tab sis kev sib txawv ntawm cov khoom siv me me yog qis dua ntawm cov khoom txias no.
Kev Kho Cua Sov
Normalizing\/quenching: Refine the grains through normalizing, and tempering treatment is required after quenching to reduce the brittleness of martensite and improve the comprehensive mechanical properties.
Cov txheej txheem Quenching Quenching: Qee lub tuam txhab siv cov dej dej khov ua kom haum rau cov nyhuv txias.
Kev thov ntawm s355j 0 cov qauv hlau nqaj hlau
Kev tsim kho hnyav: Tsim nyog rau kev thauj hluav taws xob siab xws li cov qauv steel hlau thiab choj cov nqaj tseem ceeb.
Cov cuab yeej muaj: siv rau cranes, cov hlab ntsha siab thiab cov khoom siv tshuab cov ntsiab lus thav ntawv kom tau raws li cov muaj zog siab.
Cov chaw tsim hluav taws xob tshiab: siv rau cov qauv nrog cov huab cua siab yuav tsum muaj cua tshuab hluav taws xob thiab photovoltaic nkhaus.
