1. Dab tsi yog qhov sib txawv ntawm P265Ghgh thiab P235Gh qeb?
Teb:Qhov sib txawv tseem ceeb yog:
Siab dua tsawg kawg zog zog zog zog: 265 MPa VS 235 MPA (li no tis npe)
Ib nyuag siab dua cov pa roj carbon \/ manganese cov ntsiab lus(C tsawg dua lossis sib npaug rau {{{0}}}}. 20% vs tsawg dua los yog sib npaug rau 1.20%)
Qhov Kub Kub Kub Tsis kam: P265Gh Meej kom muaj zog txog 400 degree vs 350 degree rau P235GH
Tuab siv: Feem ntau yog siv rau ntu mus txog 120 hli vs 60mm rau P235GH
2. Qhov Yuav Tsum Tau Ua Tau Yuav Tsum Tau Yuav Tsum P265Ghghoghghoghgh?
Teb:Cov qauv yuav tsum muaj:
Yam tsawg kawg nkaus cuam tshuam lub zog: 27J at 0°C (for thicknesses >30mm)
Yeem yeem qis dua kub: Muaj nqis rau -50 degree nrog cov kev cuam tshuam cuam tshuam
Kuaj zaus: Ib Txheej Ib Ib Leeg 40 Tons lossis Cua Sov (Qhov twg yog me dua)
Kev Xeem Qhia: Transverse specimens required for thickness >30mm
3. P265Ghogh Mauv rau Astm \/ ASME sib npaug?
Teb:Kaw cov sib npaug suav nrog:
| Ntiag tug | P26 Nyem | ASME SA -516 gr 65 gr 65 | ASTM A285 GR C |
|---|---|---|---|
| Tawm los (MPA) | 265 | 240 | 205 |
| Tensile (MPA) | 410-530 | 450-585 | 380-515 |
| CEV (Max) | 0.43 | 0.45 | 0.48 |
| Lub ntsiab siv | EU Siab Hlav Hlais | Peb Siab Hlua Siab | Tso tsheb hlau loj |
4. Dab tsi yog qhov kev xaiv ua tshav kub kub rau P265GHGH?
Teb:Peb txoj kev ntau lawm:
Normalized (n): Required for thickness >30mm
Normalized dov (NR): Rau kev txhim kho kev nyuaj
Raws li-dov (ar): Tsuas tso cai rau thickness tsawg dua los yog sib npaug rau 30mm
Nco tseg:Normalization kub feem ntau 890-950 degree taug kev los ntawm huab cua txias
5. Dab tsi tshwj xeeb txiav txim siab siv thaum vuam P265GHGHGE?
Teb:Qhov tseem ceeb siv hluav taws xob tseem ceeb:
Preheat: 50-100°C recommended for thickness >25mm
Cov neeg tau txais kev: En iso {2560- ib e46 lossis e42 electrodes
Cov tswv yim tshav kub: Txwv rau 2.5KJ \/ hli rau cov khoom muaj txiaj ntsig zoo
Thoob: Xav tau thaum tuab tshaj 35 hli (580-620 degree)
Siv Nplooj ntawv CEV: Siv iiw Micrula (C + MN \/ 6+ (CR + MO + V) \/ {} (ni + cu) \/ 15)
