Thaum twg yog S235J2Qhov zooKev xaiv?
S235J2 yog tus qauv European (EN 10025-2) tsis yog- alloy structural steel, paub zoo weldability, formability, thiab toughness, txawm nyob rau hauv qis kub, qhia los ntawm 'J2' uas qhia txog 20℃cuam tshuam kev xeem. 'S' sawv cev rau cov qauv hlau, thiab '235' yog nws qhov tsawg kawg nkaus yield zog (235 N / mm²). Nws yog cov hlau tsis tshua muaj hlau uas siv dav hauv kev tsim kho, nkoj tsim, txuas hniav, thiab kev tsim vaj tsev dav dav rau nws qhov sib npaug ntawm lub zog thiab yooj yim ntawm fabrication.
Xav txog kev qhia S235J2 thaum koj qhov project muaj cov yam ntxwv no:
Standard Buildings & Structures:Warehouses, coj mus muag vaj tse, vaj tse nyob, cov neeg taug kev txuas hniav, lub teeb industrial halls.
Qhov twg vuam yog qhov tseem ceeb:Fabrications uas feem ntau welding.
Nruab nrab Loading:Qhov twg suav cov kev ntxhov siab nyob hauv nws lub peev xwm, ua kom siab dua -lub zog steel ib qho tsis tsim nyog.
Txias ib puag ncig:Qhov kev pabcuam kub tuaj yeem poob qis dua 0℃(ua tsaug rau nws -20℃cuam tshuam qhov ntsuas).
Thaum Fabrication Simplicity & Nqi yog qhov tseem ceeb:Rau cov phiaj xwm ncaj nraim nrog cov ntsiab lus txheem.
Kev sib piv nrog lwm cov kev xaiv: Thaum twg los xav txog lwm yam
| Qib Steel | Qhov tseem ceeb tshaj S235J2 | Hom Siv Case (Qhov twg nws zoo dua S235J2) |
|---|---|---|
| S355J2 | Siab zog (≈50% muaj zog dua). Txo qhov hnyav thiab cov tswv cuab loj. | Ntev - ncua kab teeb, cov kab ntim hnyav hnyav, cov qauv uas qhov hnyav lossis qhov loj me yog qhov tseem ceeb. |
| S235 JR | Tus nqi qis (me ntsis). Rimmed steel yog pheej yig dua los tsim. | Rau qhov zoo li qub, tsis yog -welded, los yog cov qauv bolted yooj yim ntawm qhov kub thiab txias uas cuam tshuam qhov hnyav tsis cuam tshuam. |
| ASTM A36 | Kev Muaj Peev Xwm Hauv Zos (hauv Asmeskas). | Cov phiaj xwm tswj hwm los ntawm Asmeskas cov lis dej num lossis qhov twg A36 yog qhov kev xaiv nyiaj txiag nkaus xwb. |
| S460ML | High zog & Zoo heev Toughness. | Tshwj xeeb, hnyav- cov qauv tseem ceeb xws li ntev- txuas txuas, siab- cov tsev nce siab, lossis cov qauv tawm sab nraud. |
Cov ntsiab lus:
S235J2 yog qhov zoo xaiv rau cov qauv siv dav dav uas qhov zoo - nkag siab qhov sib npaug ntawm weldability, toughness, thiab tus nqi yog qhov tseem ceeb. Nws txoj kev siv tseem ceeb yog nyob rau hauv cov tsev tsim khoom, cov tsev khaws khoom, thiab cov thav ntawv txhawb nqa yuav tsum muaj kev thauj khoom nruab nrab, tshwj xeeb tshaj yog qhov yuav tsum tau siv vuam vuam ntau thiab kev pabcuam kub yuav poob mus rau -20℃. Nws yog qhov tseem ceeb ntawm kev lag luam "workhorse" steel, muab kev kwv yees 235 MPa lub zog tawm los, zoo heev ductility rau kev nyab xeeb, thiab yooj yim fabrication yam tsis tas yuav siv nyiaj ntau dua - qib zog. Nws yog qhov kev xaiv zoo tshaj plaws thaum cov qauv tsim ua ntej yog kev ntseeg siab, kev yooj yim, thiab tag nrho cov phiaj xwm kev lag luam tshaj qhov ua kom muaj zog tshaj - rau qhov hnyav piv.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau cov qauv tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
