Cov yam ntxwv tseem ceeb ntawm SMA400AW
1. Cov Qauv Qauv & Cov qhab nia sib npaug
| Ntiag tug | Cov ntsiab lus |
|---|---|
| Lub hom phiaj | JIS G 3106 (Welded qauv dov steel) |
| Ntaus | Huab Cua Hlau (A Tsis tau=ecmogroger corrosion Resistant) |
| Cov qhab nia sib piv | ASTM A588 (Tebchaws Asmeskas), ENGA), EN &5 S355J0WP (EU), yog 2062 wr50b (Is Nrias teb) |
2. Tshuaj lom neeg sib xyaw (%)
| Lub ntsiab | C (max) | Si (max) | Mn (max) | P (max) | S (max) | CU | Cr |
|---|---|---|---|---|---|---|---|
| Qho deb | 0.20 | 0.55 | 1.60 | 0.035 | 0.035 | 0.25-0.55 | 0.30-1.25 |
Tooj Liab (Cu) & Chromium (CR): Txhim khu kev tiv thaiv corrosion los ntawm kev sib sau cov txheej xeb tiv thaiv ("patina").
Cov pa roj carbon tsawg (c): Kom zoo weldability.
3. Cov Khoom Siv Kho Tshuab
| Teem nqi | Yield zog (MPA, min) | Tensile lub zog (mpa) | Elongation (% min) |
|---|---|---|---|
| Smau400aw | 400 | 490-610 | 17(Yog t tsawg dua los yog sib npaug rau 16 hli) |
Siab Zog: Haum rau load-cov kabmob qauv.
Kev Cuam Tshuam: Feem ntau ntsib27J ntawm -5 degree(Charpy V-NotC).
4. Corrosion Kuj
Cov ntaub ntawv aRuaj Khib TxheejThaum nthuav tawm huab cua, txo qis ntxiv corrosion.
2-8 x Lifespanvs. carbon steel nyob rau sab nraum zoov ib puag ncig.
Fabrication & Vuam Cov Lus Qhia
Txiav: Ntshav ntshav, laser, lossis oxyfuel pom zoo.
Vuam: SivCov hluav taws xob qis-hydrogen) (piv txwv li, E7018).
Preheating: Required for thick plates (>25mm).
Dabtsi yog khoov: Ua tau tab sis yuav tsum tau txua cov cuab yeej tsim nyog vim muaj zog siab.
