S275J2 Tus me kub kub dov steel h nqaj
S275J2 Kub dov hect hlau tau muab cov cuab yeej siv uas tsis xav tau, cov cuab yeej siv, Wull muaj cov kav dej muaj zog, tuaj yeem ruaj khov, kev nyab xeeb thiab kev nyab xeeb.
Cov yam ntxwv tseem ceeb
Tsawg qhov kub kub nruj: s275j2 me me hlau h nqaj yog tsim rau cov ntawv thov uas xav tau kev tiv thaiv kom loj heev ntawm qhov kub tsawg.
Weldability: cov ntsiab lus carbon tsawg tso cai ua zoo vuam cov yam ntxwv tsis muaj preheating.
Ductility: pub dabtsi yog khoov thiab sib sau yam tsis muaj kev tawg.
Qhov ruaj khov: Tiv thaiv deformation thiab hnav, ua kom muaj kev pabcuam ntev ntev.
Kev thov ntawm S275J2 kub dov hect hlau
Kev Tsim Kho: Tsev thav ntawv, txuas hniav thiab cov qauv kev lag luam hauv huab cua txias.
Infrastructure: cov chaw nres tsheb ciav hlau, tshav dav hlau thiab chaw ntau pob.
Cov Machinery: nkhaus thiab thav ntawv rau cov khoom siv loj hauv kev ua haujlwm hnyav.
Offshore qauv: Platforms, Piers thiab lwm cov ntawv thov marine.
Gnee muaj S275J2 H-Beams uas ua raws li cov qauv hauv qab no:
En 10025-2}: cov khoom siv cov kev qhia rau cov hlau tsis-alloy qauv hlau.
CE Cim: Ua kom raws li kev nyab xeeb hauv European, kev noj qab haus huv thiab ib puag ncig.
ISO Cov Qauv: Tej zaum kuj tuaj yeem ntsib cov qauv hauv ntiaj teb zoo thiab kev ua tau zoo.
Kev sib piv nrog lwm qib
S275J {0 vs. S275J2: Ob theem muaj cov txiaj ntsig zoo sib xws ntawm qis dua kub ({}}}}}}}}}}}}}}}
S275JR Vs. S275JT2: S275JR muaj kev cuam tshuam tsawg dua hluav taws xob kev xav tau thiab feem ntau yog siv nyob rau hauv cov ntawv thov tsawg dua.
