En 10025-2 s355J2 H Nqaj Hlau Qauv
S3555J2 H Beam qauv yog lub zog siab, qis alloy qauv hlau teev nyob rau hauv European steel tau teev nyob rau hauv kev tsim kho thiab engineering kev siv.
Lub ntsiab nta ntawm S355J30 h nqaj Steel qauv
Lub zog siab: Cov kabmob thauj khoom zoo heev piv tau rau qis qib steel.
Cryogenic Tougness: Tsim los rau cov ntawv thov uas xav tau kev tiv thaiv kom loj heev rau brittle baciture ntawm tsawg kub.
Zoo tshaj Weldability: Haum rau vuam tsis muaj preheating vim muaj cov ntsiab lus carbon tsawg.
Ductility: Tso cai rau kev sib sau thiab cov duab yam tsis muaj kev tawg.
Qhov ruaj khov: Tiv thaiv deformation thiab hnav, ua kom muaj kev pabcuam ntev ntev.
Kev sib piv nrog lwm qib
S355J {{0 vs. S355j2: Ob Qib 50: Ob Qib Tau Zoo Sib Xws Xub Zog thiab Tensile lub zog.
S3555j2 muaj kev cuam tshuam zoo tshaj plaws ntawm qis dua kub ({}}} 0), ua rau nws haum rau cov chaw txias.
S355JR thiab S355JT2: S355JR muaj qhov cuam tshuam tsawg dua hluav taws xob kev xav tau thiab feem ntau yog siv nyob rau hauv cov ntawv thov tsawg dua.
Gnee muaj s355j2 txheej txheem ກ້ອງ txheem hluav taws xob h nqaj uas ua rau 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.
S355J2 Cov Txheej Txheem H BARS muaj feem ntau siv nyob rau hauv:
Kev Tsim Kho: High-Rauv Vaj Tse, Txuas hniav thiab cov qauv kev lag luam.
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 qauv: Platforms, Piers thiab lwm cov ntawv thov tub nce nkoj uas xav tau lub zog siab thiab tawv.
