Dab tsi yog qhov siv tau zoo ntawm S235J0 siab zog steel hauv kev tsim kho?
S235J0 yog tus qauv European (EN 10025-}2) tsis yog{11}} alloy carbon structural steel, paub txog nws qhov zoo weldability thiab toughness ntawm qhov kub thiab txias, muaj qhov tsawg kawg nkaus yield zog ntawm 235 MPa thiab lav 27 Joules cuam tshuam lub zog ntawm 0 degree, ua rau nws zoo tagnrho rau kev tsim kho, kev tsim kho, kev siv hluav taws xob. Lub "S" qhia txog cov qauv hlau, "235" nws lub zog tawm los, thiab "J0" nws qhov kev xav tau ntawm 0℃toughness, feem ntau muab raws li kev tswj lossis cua dov phaj.
Cov txiaj ntsig tseem ceeb rau kev siv tau zoo
Guaranteed Tsawg-Kev Ua Haujlwm Kub: Nws yog tus nqi tshaj plaws- qib zoo hauv tsev neeg S235 uas muaj ntawv pov thawj kev ua haujlwm ntawm 0℃. Qib tom ntej, S235J2 (kuaj ntawm -20 degree), yog kim dua thiab tshwj xeeb rau cov mob hnyav dua.
Weldability zoo heev: Zoo li txhua qib S235, nws muaj qhov sib npaug ntawm cov pa roj carbon tsawg, tso cai rau kev vuam yooj yim yam tsis muaj kev nyuaj ua ntej- cov txheej txheem cua sov hauv feem ntau cov tuab, uas yooj yim rau ntawm - qhov chaw tsim kho.
Kev Lag Luam Nyiaj Txiag: Nws muab kev txhim kho kev nyab xeeb tseem ceeb tshaj S235JR ntawm tus nqi qis qis xwb. Rau cov haujlwm uas qhov kev qhia tshwj xeeb hu rau "steel haum rau qhov kub thiab txias mus rau 0 degree," S235J0 yog tus qauv, muaj kev daws teeb meem.
Kev tsim qauv tseem ceeb thiab kev txiav txim siab xaiv
Paub Koj Qhov Kev Pab Cuam Yam Tsawg: Qhov kev xaiv ntawm JR ({0}}℃), J0 (0℃), thiab J2 (-20 degree) yog tsav los ntawm qhov kub qis tshaj tus qauv yuav muaj kev pabcuam. Cov cai hauv zos feem ntau tswj cov qib no raws li thaj chaw thaj chaw.
Tsis yog Siab -Txoj kev daws teeb meem: Yog tias tus qauv tsim thawj tsav tsheb yog qhov hnyav txo lossis ncua ntev, S355 qib yuav ua tau zoo dua. S235J0 yog xaiv rau toughness, tsis muaj zog.
Fabrication Consistency: Nws cov khoom yog txhim khu kev qha thiab zoo ib yam, uas yog ib qho tseem ceeb rau kev tswj kom zoo nyob rau hauv cov ntaub ntawv tseem ceeb.
Sib piv & Summary
| Qib | Qhov zoo tshaj plaws siv rau ... | Kev xav |
|---|---|---|
| S235 JR | Cov qauv sab hauv tsev, lossis cov qauv sab nraum zoov hauv huab cua sov / me me (piv txwv li, Southern Europe). | Kev lag luam feem ntau. Txaus toughness rau saum toj no - khov temps. |
| S235J0 | Sab nraum cov qauv, txuas hniav, thiab kev sib txuas tseem ceeb hauv cov huab cua nrog lub caij ntuj no txias (temps mus rau ~ 0 degree). | Muab qhov tseem ceeb kev nyab xeeb npoo tiv thaiv brittle fracture ntawm tus nqi qis. |
| S235J2 | Cov qauv nyob rau hauv arctic los yog hnyav alpine huab cua, los yog rau qhov tseem ceeb heev Cheebtsam uas kub yuav poob qis dua -10℃rau -20 degree. | Kev nyuaj siab tshaj plaws hauv tsev neeg S235 rau qhov chaw txias tshaj plaws. |
Xaus
Kev siv tau zoo ntawm S235J0 yog lub hom phiaj siab: Nws yog lub neej ntawd, kev lag luam muaj txiaj ntsig zoo rau kev ua kom muaj kev ncaj ncees thiab tawg kev nyab xeeb hauv cov khoom siv hlau raug kub los yog ze 0 degree. Nws tus nqi yog tsis nyob rau hauv nws lub zog, tab sis nyob rau hauv nws cov ntaub ntawv pov thawj thiab guaranteed toughness nyob rau hauv ib puag ncig tej yam kev mob uas yuav ua rau cov qauv steel qib uas tsis muaj kev nyab xeeb. Thaum tus qauv tsim kub poob qis, qhov qhia meej S235J0 yog qhov tseem ceeb thiab tsis yog -kev txiav txim siab engineering rau kev nyab xeeb.
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 kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
