S355m kub dov h nqaj hlau

S355m kub dov h-nqaj yog lub zog loj qauv qauv qauv siv hauv kev tsim kho, engineering thiab ntau yam kev siv khoom.

S355m yog cov qauv tsis-alloy qauv hlau uas ua raws li European cov qauv en {2}}. Tus "m" qhia tias cov hlau tau siv cov thermiochaananically dov, uas tau txhim kho cov khoom siv neeg kho tshuab.

Tshuaj lom neeg muaj pes tsawg leeg ntawm S355m H-Beam
Cov pa roj carbon (c): {0. {12 - 0. 22%
Manganese (MN): 1. 00 - 1. 60%
Silicon (Si): {0. {20 - 0. 55%
Phosphorus (p): tsawg dua lossis sib npaug rau 0. 025%
Sulphur (s): tsawg dua los yog sib npaug rau 0. 025%
Tooj liab (Cu): tsawg dua los yog sib npaug rau 0. 55%

Cov Khoom Siv Neeg Kho Tshuab ntawm S355M H-nqaj kab
Paib lub zog: ntau dua los yog sib npaug rau 345 mpa
Lub zog tensile: {490 - 630 mpa mpa
Elongation: ntau dua los yog sib npaug rau 17%
Cuam tshuam tus nqi (-20 degree charpy v-imch): ntau dua lossis sib npaug rau 27 j

Qhov loj me thiab cov lus qhia tshwj xeeb: H-Beam yog nqaj ib qho "I" lossis "H" "H" "H" ntawm Flanges ib qho dav dua li lub vev xaib kom muab qhov zoo dua BENDER YIG. Ntau qhov ntau thiab tsawg ntawm 100mm X 100mm X 100mm X 300 hli, thiab ntev tuaj yeem sib txawv ntawm 6 metres, nyob ntawm tus neeg siv khoom yuav tsum tau ua.

S355m Kub Rolled Steel muab los ntawm GNee yog tsim raws li en {1}} tus qauv kuaj, thiab peb muab cov qauv kuaj ntsuas Hoobkas raws en 10204 kom ntseeg tau tias qhov zoo thiab ua raws li cov hlau.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
