914x419X {446 914 x419x488 s355jr Universal nqaj
S355JR cov qauv hlau nqaj yog qhov qis-alloy cov qauv hlau uas tau raws li European cov qauv en {3}}. Nws cov tshuaj lom neeg muaj cov pa roj carbon (c) tsawg dua lossis sib npaug ntawm}}}}}}}}}}}}}}}}}}}}. lossis sib npaug rau 0.025%.
S355jr Cov Khoom H nqaj muaj cov khoom muaj txiaj ntsig zoo los ntawm kev ntxiv ib qho me me ntawm alloy. Cov txiaj ntsig lub zog tsis pub tsawg tshaj 355MPA, lub zog tensile yog nruab nrab ntawm {2}} mpa, thiab elongation tom qab pob txha lov yog tsis pub tsawg tshaj 22%.
Piv nrog s355j 0 steel nqaj h, qhov kev cuam tshuam kev ntsuas kub ntawm s355jr h Beam khoom yog 20 degree. Nws muaj qhov cuam tshuam zoo ntawm chav sov thiab tuaj yeem tiv taus ib co lej ntawm kev cuam tshuam thiab kev co cov khoom thauj.
H-Beam Cov Kev Sib Tw Tshwj Xeeb
914x449x446 H nqaj ntu: Qhia tau tias qhov siab ntawm qhov profile yog 414 hli, qhov hnyav dav rau ib 'meter' yog 446kg.
914x429x488 h profile steel: Qhov siab ntawm qhov profile yog 914mm, qhov hnyav dav rau ib 'meter' yog 48kg.
Cov yam ntxwv ntawm cov txheej txheem Universal hlau
Lub zog siab: Vim muaj lub zog loj ntawm S355JR tuaj yeem tiv thaiv cov khoom loj loj, cov qauv hluav taws xob ntawm cov vaj tse loj, txhawb cov cuab yeej loj, thiab lwm yam.
Zoo toughness: nws muaj cov kev cuam tshuam zoo ntawm chav nyob (20 degree), thiab tuaj yeem nqus tau ib qho kev nyab xeeb lossis kev txhim kho kev nyab xeeb thiab kev ntseeg tau ntawm cov qauv.
Yooj yim ua: nws muaj kev ua tiav zoo thiab tuaj yeem ua rau hauv cov khoom siv thiab ntau los ntawm ntau yam duab thiab lwm txoj kev ua kom tau raws li cov kev xav tau ntawm cov kev siv tshuab sib txawv. Ntxiv mus, thaum ua tiav, kev ua yeeb yam ntawm cov hlau yuav tsis muaj cuam tshuam loj heev, thiab qhov zoo ntawm cov txheej txheem txheej txheem tuaj yeem lav.
Zoo corrosion: hauv ib puag ncig huab cua, nws muaj qhov zoo corrospherion tiv taus, tuaj yeem tiv thaiv qee qhov kev ua kom xeb thiab xeb, thiab txuas ntxiv kev pabcuam lub neej ntawm cov qauv.
