1. Kev Taw Qhia: Qib Ib Yam, DNA Sib Txawv
Hauv cov qauv hlau,S355J2Hyog ib qho kev xav tau raucov seem khoobTxawm li cas los xij, nws zoo li nyob rau hauv ob qho qauv tsim khoom sib txawv:EN 10210thiabEN 10219Txawm hais tias lub npe "S355J2H" feem ntau ua rau cov neeg yuav khoom xav tias lawv zoo ib yam, txoj kev tsim khoom - thiab yog li ntawd qhov kev ua tau zoo - txawv ntau heev.
Tsab xov xwm no piv rau EN 10210 S355J2H (Kub Tiav) piv rau EN 10219 S355J2H (Tawv Tsim) kom meej meej lawv qhov sib txawv ntawm cov khoom siv kho tshuab, cov yam ntxwv pom, thiab kev siv tau.
2. Qhov Txawv Tseem Ceeb: Cov Txheej Txheem Tsim Khoom
EN 10210 - Kub tiav (S355J2H)
Cov seem hauv qab EN 10210 yog tsim los ntawm qhov kub siab (feem ntau siab dua qhov kub recrystallization). Cov txheej txheem "Kub Tiav" no txo cov kev ntxhov siab sab hauv uas tsim thaum lub sijhawm shaping. Hauv EN 10210, S355J2H feem ntau tsim los ntawm txoj kev Stress Relied (cua sov hauv qab 850 ° C) lossis txoj kev Fully Normalized (cua sov saum ~ 850 ° C los pib dua cov qauv noob). Cov raj Fully normalized muab cov ductility zoo dua thiab sib xws.
EN 10219 - Txias Tsim (S355J2H)
Cov seem raws li EN 10219 yog puab ntawm chav tsev kub los ntawm cov hlau kauj lossis phaj. Cov hlau raug khoov thiab tom qab ntawd welded (feem ntau ERW lossis SAW). Qhov kev ua haujlwm txias no ua rau cov hlau tawv, tshwj xeeb tshaj yog ntawm cov khoov thiab cov ces kaum, xauv rau hauv cov kev ntxhov siab siab.
3. Kev Sib Piv Txog Cov Lus Qhia Txog Kev Siv (S355J2H)
Txawm hais tias cov kev txwv ntawm cov tshuaj lom neeg sib xyaw zoo ib yam, qhov kev ua tau zoo ntawm cov khoom siv thiab kev kam rau siab hloov pauv vim yog txoj kev tsim.
| Vaj tse | EN 10210-1(Kub tiav lawm) | EN 10219-1(Ua Txias) |
| Tsim Kub | Saum toj no Recrystallization (Kub) | Kub Ib puag ncig / Chav (Txias) |
| Lub Zog Tawm (ReH) (T ≤ 16 hli) | ≥ 355 MPa | ≥ 355 MPa |
| Lub zog tensile (Rm) (3 hli ≤ T ≤ 40 hli) | 470 – 630 MPa | 470 – 630 MPa *(Ceeb Toom: EN10219 cov npe teev tseg 490-630 rau T<3mm)* |
| Kev ntev | Yam tsawg kawg nkaus 22% (Kev ua kom du thiab yooj yim dua vim yog kev kho cua sov) | Yam tsawg kawg nkaus 20% (Qis dua vim yog kev ua haujlwm tawv) |
| Kev Cuam Tshuam Toughness (KV) | 27J @ -20°C | 27J @ -20°C |
| Kev Nyuaj Siab seem | Qis (Zoo siab los ntawm cua sov) | Siab (Xauv rau hauv kev tsim) |
| Lub kaum sab xis (SHS/RHS) | < 2T (Nruj dua, ntse dua) | 1.6T ~ 3.6T (Lub vojvoog loj dua) |
4. Kev Sib Txawv ntawm Qhov Muag thiab Qhov Ntev
Qhov "Ntsuas" (Kev Nyuaj Siab seem): Cov seem uas txias lawm (EN 10219) muaj qhov ib txwm "nyo rov qab" lossis "ntxig" thaum txiav vim yog lub zog seem khaws cia. Cov seem uas kub tiav lawm (EN 10210) tseem ruaj khov tom qab txiav.
Cov Ces kaum: Rau cov seem plaub fab thiab plaub fab plaub fab (SHS/RHS), EN 10219 tso cai rau lub ces kaum vojvoog txog li 3.6 npaug ntawm qhov tuab ntawm phab ntsa (T), ua rau cov ces kaum puag ncig heev. EN 10210 cov seem kub tiav (tshwj xeeb tshaj yog cov seem normalized) ua tiav lub vojvoog ntse dua (feem ntau < 2T), muab qhov chaw tiaj tiaj loj dua.
Phab Ntsa Thickness: EN 10210 feem ntau muab cov thickness tolerances nruj dua piv rau EN 10219.
5. Koj Yuav Tsum Xaiv Qhov Twg?
XaivEN 10210-1 S355J2Hyog tias:
Cov ntawv thov tseem ceeb ntawm cov qauv: Choj, crane booms, seismic zones, lossis offshore platforms.
Kev Tiv Thaiv Kev Qaug Zog Siab: Kev vuam lossis kev thauj khoom dynamic xav kom cov khoom siv muaj kev ntxhov siab tsawg kom tiv thaiv kev tawg.
Kev xav tau kev zoo nkauj/kev raug: Koj xav tau cov ces kaum nruj thiab qhov ncaj uas kwv yees tau rau cov hlau uas nthuav tawm hauv tsev.
Kev ua kub: Yog tias koj npaj yuav ua qhov kub khoov lossis ua qhov kawg, cov khoom siv ib txwm ua tau zoo dua.
Xaiv EN 10219-1 S355J2H yog tias:
Kev siv nyiaj tsim nyog: Kev tsim txias feem ntau pheej yig dua thiab sib dua rau ib qho me me.
Kev tsim kho dav dav: Cov tsev qis qis, cov plag tsev mezzanine, cov ncej laj kab, lossis cov khoom siv ua liaj ua teb qhov twg qhov kev ntxhov siab me me tsis yog qhov txaus ntshai ntawm kev ua tsis tiav.
Muaj: Nws yog lub raj "txheem" feem ntau pom muaj nyob rau hauv cov khw muag khoom thoob ntiaj teb.
6. Ib qho Lus Ceeb Toom Tseem Ceeb rau "S355J2H"
Ceev faj: Tsis yog txhua lub raj EN 10210 S355J2H yog tsim los sib npaug.
Cov chaw tsim khoom tuaj yeem tsim cov raj EN 10210 los ntawm "Kev Nyuaj Siab Relieve" lossis "Fully Normalized."
Tus Qauv S355J2H (Kev Txo Kev Nyuaj Siab): Ua tau raws li tus qauv tab sis tseem khaws qee qhov kev nyuaj siab. Nws pheej yig dua.
S355NH (Qib Ib Txwm): Ib qib tshwj xeeb raws li EN 10210 uas xav tau kev kho kom zoo tag nrho (kub siab). Qhov no yog cov khoom zoo tshaj plaws rau kev vuam.
Yog tias koj xav tau qhov ductility siab tshaj plaws thiab tsis muaj kev ntxhov siab seem rau kev vuam, hloov kho koj cov spec mus rau EN 10210 S355NH es tsis yog tus qauv J2H.
