En 10210 steel qib overview
En 10210 npogKub-tiav Cov Qauv Hollow(kav dej, square \/ plaub hau hlab) ua los ntawmTsis-Alloy thiab Zoo-Grain SteelsCov. Cov qib (S235, S275, S355) sib txawv feem ntau hauvPepred lub zog, tej yam nyuaj, thiab tshuaj lom neeg muaj pes tsawg leeg, ua txhua yam haum rau cov ntawv thov tshwj xeeb.
| Teem nqi | Paib lub zog (rov qab) | Lub zog tensile (RM) | Cov yam ntxwv tseem ceeb |
|---|---|---|---|
| S235 | Ntau dua los yog sib npaug235 MPa | 360-510 MPa | Qis tshaj plaws lub zog, zoo heev veldability, nqi-raug nqi. |
| S275 | Ntau dua los yog sib npaug275 mpa | 430-580 MPA | Ntsuas lub zog \/ ductility, general-hom phiaj siv. |
| S355 | Ntau dua los yog sib npaug355 MPa | 470-630 MPa | Lub zog siab, txhim kho nruj (tshwj xeeb J2H \/ K2H cov qib). |
Cov ntaub ntawv ntxaws ntxaws los ntawm qib
S235 (piv txwv li, s235jrh, s235J {3}} h, s235j2h)
A.typical siv:
- Lub teeb yuag:
Ru hlau trusses, scaffolding, thiab txhawb thav ntawv.
Cov kws txawj kos duab (piv txwv li, canopies, façades) qhov twg siab zog tsis yog qhov tseem ceeb.
- Tsis yog-tseem ceeb heev infrastrastrastrastrasure:
Handrails, Signage qauv, thiab kev teeb tsa ib ntus.
Khoom siv ua liaj ua teb (piv txwv li, tsev cog khoom ntas).
B.Advantages:
- Yooj yim rau Weld Thiab TshuabVim yog cov ntsiab lus roj carbon monoxide.
- Nqi-ZooRau cov phiaj xwm nrog tsawg heev load yuav tsum tau ua.
C.limitations:
- Tsis haum rau hnyav-thauj lossis qis-qhov chaw dej (tshwj tsis yog muaj kev cuam tshuam-xeem qib nyiamS235J2Hsiv).
S275 (e.g., S275J0H, S275J2H)
A.typical siv:
- Kev Siv Dav Dav:
Nruab Nrab-thauj cov thav ntawv thav ntawv, kev taug kev lag luam, thiab platform.
Cov Cheebtsam Choj (cov ntsiab lus theem nrab, neeg taug kev cov neeg taug kev).
- Thauj & Machinery:
Chassis qhov chaw rau cov tsheb thauj khoom \/ shocks, crane booms.
Cov qauv kev txhawb nqa rau conveyor tshuab.
B.Advantages:
- Zoo dua lub zog-rau-hnyav pivtshaj li S235, txo cov khoom siv khoom siv.
- Zoo Weldabilitynrog polerate nruj (piv txwv li,S275J2Hrau -20 degree degree).
C.limitations:
- Tsawg dua kev lag luam tshaj S355 rau cov ntawv thov kev ntxhov siab muaj kev ntxhov siab.
S355 (e.g., S355J0H, S355J2H, S355K2H)
A.typical siv:
- Hnyav-Cov Qauv Txheej Txheem:
High-nce tsev, offshore roj rigs, thiab cua tshuab raj.
Txuas hniav (cov kabmob tseem ceeb).
- Qhov tseem ceeb ib puag ncig:
S355J2H/K2H:Arctic Pipelines, cov khoom siv me me, thiab cov khoom siv mining (resazing brittle bacture ntawm {{0} degree).
Av qeeg-resistant qauv (muaj zog nqus).
B.Advantages:
- Superior zogTso cai rau cov ntawv nyias nyias, txuag qhov hnyav \/ nqi.
- Txhim Kho Cov Tougning(tshwj xeeb yogS355K2HNrog 40j cuam tshuam lub zog ntawm -20 degree).
C.limitations:
- Siab dua li S235 \/ S275.
- Tej zaum yuav tsum tau preheated rau vuam nyob rau hauv cov kab tuab.
