S235JR Txheej Txheem H Hlau Beooj
S235jr h Beam qauv yog dav siv hauv kev tsim kho thiab kev tsim kho vim nws cov kws tsim khoom zoo, yooj yim ntawm kev tsim khoom thiab tus nqi-ua hauj lwm zoo. "S" sawv rau cov qauv hlau, "yog hais txog qhov tsawg kawg nkaus muaj zog hauv MPa, thiab" JR "yog hais txog cov khoom siv ntawm chav tsev kub (27 joules ntawm 20 degree).
H-nqaj, tseem hu ua cov flange flange steel, muaj ib ntu "H" zoo nkauj, suav nrog Flange: Kab rov tav uas muab rau kev cuam tshuam los khoov; Lub Vev Xaib: Ib feem ntsug uas txuas cov flanges thiab tawm tsam shear rog.
S235JR H yog tsim tau siv cov txheej txheem kub yob kom ntseeg tau tias muaj ntau thiab ntau thiab gnee muaj ntau yam ntawm cov dej num muaj txiaj ntsig ntawm cov haujlwm tshwj xeeb.
Cov ntawv thov ntawm S235jr H Beam Steel qauv
Kev Tsim Kho: Tsev thav ntawv, cov chaw muaj chaw nyob thiab vaj tse nyob.
Infrastructure: choj, kev loj thiab kev tsheb ciav hlau.
Cov Machinery: Pab txhawb nqa qauv rau cranes, cov khoom siv mining thiab ntug platform.
Tubrog marine: Offshore platforms, shrbuildiling thiab chaw nres nkoj cov chaw.
Qhov Zoo ntawm S235JR H Beams
Siab zog-rau-nyhav piv: muab kev thauj khoom zoo heev uas tsis muaj qhov hnyav tshaj.
Yooj yim rau Fab Kis: tuaj yeem txiav, welded, drilled thiab tsim cov cuab yeej txheem.
Qhov ruaj khov: Tiv thaiv deformation thiab hnav nyob rau hauv cov kev ua haujlwm ua haujlwm li qub.
Weldability: tsawg cov ntsiab lus cov ntsiab lus thiab tswj tau cov ntsiab lus zoo muab cov ntsiab lus muaj kev cuam tshuam zoo heev.
S235JR Cov Txheej Txheem Hlau H Be tws muab los ntawm GNEE raws li cov qauv hauv qab no:
En 10025-2: Txheem rau cov hlau tsis-alloy qauv hlau.
ASTM A36: Cov khoom siv mecha tshuab yog sib piv rau S235JR.
JIS G3101 SS400: Tso lub zog thiab tensile lub zog zoo ib yam li S235JR.
Peb muab cov ntawv pov thawj xws li ISO 9001 kom paub tseeb tswj tau thaum lub sijhawm ntau lawm.
Kev sib piv nrog lwm qib
