EN 10219 S235JRH - Cov leeg hlau (cov khaub ncaws txias welded)
Txheem & Tshwj Xeeb
Rau 10219yog European tus qauv uas qhia txog cov kev ua haujlwm ntawm kev kawm rauTxias-tsim Welded Cov Qauv Hollow(Facular, square, thiab duab plaub) ua los ntawm cov tsis-alloy thiab cov hlau nplaum zoo-lis.
S235jrhyog cov qauv txheej txheem steel hauv qab no tus qauv no.
Qib Qauv Hlau: S235JRH
S235: Qhia txog tusYam tsawg kawg nkaus xwb ZogNtawm 235 MPa (ntawm chav sov, tsawg dua los yog sib npaug rau 16 mm tuab).
J: Qhia rau tusKev Cuam Tshuam Lub Zog(27 j ntawm 0 degree).
R: Qhia tias cov hlau yogtxias-tsim (dov).
H: Txhais tau tias cov khoom siv yog npaj rauHollow cov teeb meem.

- Cov hlau muaj aCov ntsiab lus muaj roj carbon tsawg, tuaj yeem pab txhawm rau txhim kho lub weldability ntawm cov hlau. Nws txo txoj kev pheej hmoo ntawm kev ua kom tawv nqaij tawv thiab tawg thaum lub sijhawm ua vuam.
- Nws yuav muaj lwm cov khoom sib txuas me xws li manganese, silicon, thiab leej faj thiab phosphorus. Cov ntsiab lus no pab kom ua kom ua kom ua kom zoo nkauj cov qauv sib dhos ntawm cov hlau, txhim kho nws lub zog, thiab txhim kho nws txoj kev nruj.
Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | Yield zog (mpa) | Tensile lub zog (mpa) | Elongation (%) | Cuam tshuam lub zog (j) |
|---|---|---|---|---|
| Tus nqi | Ntau dua los yog sib npaug rau 235 (nominal tuab tsawg dua lossis sib npaug rau 16 hli) | {{0 {0}} (nominal thickness <3mm) | Ntau dua los yog sib npaug rau 24 | Ntau dua los yog sib luag rau 27 (thaum 0 degree) |
- Haum rauCov ntawv thov txheej txheemQhov twg muaj lub zog muaj zog thiab qhov ua tau zoo yog qhov yuav tsum tau ua.
- Cov txiaj ntsig lub zogyog tsawg kawg235 MPaCov. Qhov no yog qib kev ntxhov siab uas cov hlau pib ua kom deform plastically. Nws txhais tau tias cov hlau tuaj yeem pab txhawb nqa cov khoom siv qib no yam tsis muaj kev cuam tshuam nrog.
- Lub zog tensilentawm s235jrh hlau yog nyob rau hauv cov ntau ntawm360 - 510 mpaCov. Qhov no yog qhov kev ntxhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus ua ntej nws tawg. Qhov ntau ntawm ntau ntawm tensile lub zog yog vim muaj kev sib txawv hauv cov txheej txheem tsim khoom thiab cov khoom sib xyaw tshwj xeeb ntawm cov hlau.
- Elongationthaum so yog ib txwm nyob ib puag ncig24%Cov. Qhov no qhia tau tias qhov ductility ntawm cov hlau. Nws txhais tau hais tias cov hlau tuaj yeem ncab mus txog 24% ntawm nws cov qub ntev ua ntej nws poob. Qhov ductility no yog qhov tseem ceeb rau kev siv uas cov hlau yuav raug rau khoov lossis lwm hom kev deformation.
Kev tsim khoom & kev ua
Txias-tsim thiab weldedrau hauv hollow ntu.
Kev Kho Cua Sov(Yog tias yuav tsum tau) txhim kho cov khoom siv mechanical.
Qhov xwm txheej nto:Feem ntau muab nrog lub zeb ua tiav lossis galvanized rau corrosion tsis kam.
Cov Ntawv Thov
Kev tsa tsev: Tsim cov thav ntawv, txuas hniav, kev txhawb nqa qauv.
Cuab Yeej Siv Hluav Taws Xob: Muab cov tshuab hluav taws xob, scaffolding.
Yam muaj hauj lwm: MACHINERY thav ntawv, cia lub tshuab.
Txias-ua haum: Qhov zoo rau kev khoov thiab vuam.
