Lub ntsiab
En 10210 yog European tus qauv uas qhia txog cov ntaub ntawv kev ua tiav Hollow Cov Lus Qhia Hollow Lub S275 qib yog ib qho qauv hlau ib txwm muaj hlau nrog tsawg kawg yog cov txiaj ntsig lub zog ntawm 275 MPa. Ob qho tseem ceeb tshaj plaws hauv qab no yog:
- S275J0H- Kev cuam tshuam xeem ntawm 0 degree.
- S275J2H- Kev cuam tshuam xeem ntawm -20 degree.
Cov kawm hauv cov qib no tau siv dav siv hauv kev tsim kho, cov choj, thiab lwm yam kev coj ua-coj los ntawm lawv cov txiaj ntsig zoo, lub zog, thiab tawv.
Tshuaj lom neeg muaj feem (nominal muaj nuj nqis,% los ntawm qhov hnyav)
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm S275J {1}} h thiab s275j2h yuav tsum ua raws li en {4}}. Cov ntsiab lus tseem ceeb suav nrog:
| Lub ntsiab | S275J 0 h (max%) | S275J2H (Max%) |
|---|---|---|
| C | Tsawg dua los yog sib npaug rau 0. 20 | Tsawg dua los yog sib npaug rau 0. 20 |
| Si | - | - |
| Mn | Tsawg dua los yog sib npaug rau 1.50 | Tsawg dua los yog sib npaug rau 1.50 |
| P | Tsawg dua li lossis sib npaug rau 0. 035 | Tsawg dua li lossis sib npaug rau 0. 035 |
| S | Tsawg dua los yog sib npaug rau 0. 030 | Tsawg dua los yog sib npaug rau 0. 030 |
Nco tseg:S275J2H muaj cov kev txwv uas txwv tsis pub dhauPthiabSrau kev txhim kho kev nyuaj ntawm tsis kub.
Cov Khoom Siv Neeg Kho Tshuab
Cov cuab yeej ua haujlwm (en 10210-2}) rau cov ntu hollow tiav yog:
| Ntiag tug | S275J0H | S275J2H |
|---|---|---|
| Paib lub zog (RH, MPA) | Ntau dua los yog sib npaug rau 275 | Ntau dua los yog sib npaug rau 275 |
| Tensile lub zog (RM, MPA) | 410–560 | 410–560 |
| Elongation (A₅,%) | Ntau dua los yog sib npaug rau 22 | Ntau dua los yog sib npaug rau 22 |
| Kev Cuam Tshuam (Charpy V-thatch) | Ntau dua los yog sib luag rau 27 j ntawm 0 degree | Ntau dua los yog sib luag rau 27 j ntawm -20 degree |
Kev Cuam Tshuam Cov:
- S275J0H: Sim ntawm0 degree(Tsawg kawg 27 Joules).
- S275J2H: Sim ntawm-20 degree(Tsawg kawg 27 Joules), ua rau nws haum rau cov huab cua txias.
Kev tsim khoom thiab kuaj
- Cov qib steel no feem ntau yog tsim los ntawm kub dov cov txheej txheem.
- Yuav tsum tau tshuaj ntsuam suav nrog tshuaj ntsuam xyuas tshuaj lom neeg, kev kuaj mob Tensile, cuam tshuam kev soj ntsuam, thiab kev tshuaj xyuas thiab kev tshuaj xyuas kev tshaj tawm.
- Rau welded khoom, tsis yog kev ua phem rau kev sim siab (NDT) ntawm cov Welds kuj yuav tsum tau
Cov Ntawv Thov
Kev tsa tsev: Vaj tse, txuas hniav, thiab vaj tse.
Muaj cov qauv kev siv: Cov kab ntawv txhawb nqa, crane girders.
Kev mus: CHASSIS Cheebtsam (yog tias teev).
- S275J0H:Haum rau cov qauv txheej txheem dav dav xws li steel thav ntawv rau cov tuam tsev, cov cuab yeej siv lag luam tsim, thiab cov cuab yeej tsim khoom lag luam, thiab vaj tse tsim khoom lag luam, thiab vaj tse.
- S275J2H:Vim nws cov kev cuam tshuam ntau dua ntawm qhov chaw kub qis dua, nws tsim nyog rau cov ntawv thov hauv ib puag ncig hauv zej zog lossis qhov chaw muaj zog dua.
Tag
S275J {0 h thiab s275j2h muaj kev sib npaug ntawm lub zog, ducness, thiab tawv, nrog S275J2H ua tiav zoo dua-kub ua tau zoo. Lawv yog qhov zoo tagnrho rau cov ntawv thov cov kev thov uas xav tau kev ua kom ruaj khov thiab weldability.
