Dab tsi yogA633 Qib E?
A633 Qib E yog anormalized siab -lub zog, qis- alloy (HSLA) structural steelphaj, qib siab tshaj hauv ASTM A633 series. Nws yog tsim rauwelded, bolted, los yog riveted tsimthiab muabsuperior zog, cuam tshuam tsis kam, thiab tsawg-kub toughnesspiv nrog Qib C thiab D. Cov ntawv thov ib txwm suav nrogcov hlab ntsha siab, lub tank cia, txuas hniav, thiab cov khoom siv hnyav, tshwj xeeb tshaj yog nyob rau hauv txias los yog xav tau ib puag ncig.

Tej yam cuab yeej cuab tam
| Phaj Thickness | Min. Yield zog (MPa) | Tensile zog (MPa) | Elongation (%) |
|---|---|---|---|
| Tsawg dua los yog sib npaug li 65 mm | 345 (50 hli) | 485–620 | Ntau dua lossis sib npaug li 18 |
| 65-100 hli | 315 (46 hli) | 450–590 | Ntau dua lossis sib npaug li 18 |
Qib E txawv ntawm Qib C thiab D li cas?
Txheej txheem cej luam ntawm Qib
| Qib | Kev piav qhia dav dav |
|---|---|
| C | Lub hauv paus qib ntawm A633, normalized, siab -lub zog qis- alloy steel, haum rau cov qauv siv. |
| D | Siab zog thiab txhim kho toughness piv rau C; zoo dua qis-kub kev ua haujlwm; haum rau kev siv cov qauv hnyav dua. |
| E | Qib siab tshaj hauv koob; lub zog siab tshaj plaws thiab qis -kub toughness; zoo tagnrho rau cov phaj tuab, cov hlab ntsha siab, txuas hniav, thiab qhov chaw txias. |
2. Kev sib piv cov cuab yeej cuab tam
| Khoom | Qib C | Qib D | Qib E |
|---|---|---|---|
| Yam tsawg kawg nkaus tawm lub zog (MPa) | 295–345 | 315–345 | 345 |
| Tensile zog (MPa) | 430–585 | 450–620 | 485–620 |
| Elongation (%) | Ntau dua lossis sib npaug li 18 | Ntau dua lossis sib npaug li 18 | Ntau dua lossis sib npaug li 18 |
| Impact Toughness | Txuj | Siab dua C | Qhov siab tshaj plaws ntawm peb, tshwj xeeb tshaj yog nyob rau hauv qis kub |
| Phaj Thickness | Feem ntau thinner daim hlau | Txhawb cov phaj tuab | Txhawb nqa cov phaj tuab thaum tuav lub zog |
Qhov Tseem Ceeb Qhov Sib Txawv / Qhov Zoo ntawm Qib E tshaj C thiab D
Siab zog:
Qib E muaj qhov tensile siab tshaj plaws thiab lub zog tawm los ntawm peb qib.
Superior Low-Tsub Toughness:
Ua kom muaj kev cuam tshuam zoo heev ntawm qhov kub thiab txias (txog ~-45 degree).
Thicker phaj muaj peev xwm:
Qib E tuaj yeem muab tau rau hauv cov phaj tuab yam tsis muaj cov khoom siv kho tshuab, tsis zoo li C thiab D.
Heavy-Cov ntawv thov ua haujlwm:
Zoo tagnrho raucov hlab ntsha siab, lub tank cia, txuas hniav, thiab txias -cov qauv huab cua, qhov twg ob lub zog thiab toughness yog qhov tseem ceeb.
Ntawm GNEE, peb muab cov khoom zoo - cov khoom siv hlau zoo, tsim kom tau raws li koj qhov kev tsim kho tshwj xeeb. Nrog rau cov nqi sib tw, kev pabcuam txhim khu kev qha, thiab xa khoom raws sijhawm, peb muaj kev ntseeg siab hauv kev muab cov kev daws teeb meem uas yuav txhim kho koj cov haujlwm. Peb caw koj los koom tes nrog peb rau tag nrho koj cov kev xav tau steel!
