Dab tsi yog A516Gr70?
A516Gr70Yog cov phaj steel rau cov hlab ntsha siab tau teev nyob hauv Asmeskas Astm tus qauv. Ntawm no, "A516" txhais tau hais txog tus lej ntawm tus lej, thaum "Gr70" sawv cev rau nws cov txiaj ntsig lub zog. Cov hlau no feem ntau siv rau kev tsim khoom lag luam welded Cheebtsam hauv nruab nrab {4} -}} kub cov hlab ntsha. Nws ua tej yam ua pov thawj weldability thiab cuam tshuam kov.
Tshuaj Muaj Tshuaj
- Cov pa roj carbon (c): tsawg dua lossis sib npaug rau 0.30%
- Manganese (MN): 0.79-1.30%
- Phosphorus (p): tsawg dua lossis sib npaug rau 0.035%
- Sulfur (s): tsawg dua lossis sib npaug rau 0.035%
- Silicon (si): 0.13-0.45%
Yog li ntawd, A516Gr70 yog ib tug carbon qauv hlau, tsis yog stainless hlau.

Qhov tseem ceeb ntawm cov roj carbon hlau thiab hlau steel thiab stainless hlau
| Tus yam ntxwv | A516Gr70 (Cov Hlau Carbon) | Tus Hlau Stainless (piv txwv li, 304/316) |
| Cov muaj pes tsawg | Fe {-}}- mn} mn - si, lw cr, mo | High Cr (216%), NI (28%) |
| Corrosion tiv thaiv mechanism | Tso siab rau saum npoo txheej / inhibitors; Optimized rau H2S ib puag ncig corrosion tsis kam | Tso siab rau passive zaj duab xis rau tus kheej -} kev tiv thaiv |
| Theem siab nyuaj | Nruab nrab - siab zog (tawm los dag zog 2260 mpa) | Feem ntau qis zog (Austenitic SS-200 MPa) |
| Nqi | Cov nyiaj txiag ntxiv (~ 1/3 txog 1/2 tus nqi ntawm Stainless) | Kim, nyob ntawm npib tsib xee / chromium cov peev txheej |
| Ib puag ncig ib puag ncig | Kev / Tsawg Kub, Tshwj Xeeb Cov Mob Hauv Corrosive (piv txwv li, H2S) | Muaj zog oxidizing cov kua qaub, kev kub siab, lossis cov chaw ua kom huv |
Cov tub ntxhais sib txawv ntawm cov roj carbon hlau thiab stainless hlau
Muaj pestrosition sib txawv
Stainless tus hlau muaj tsawg kawg yog 10.5% chromium thiab feem ntau suav nrog lwm cov aluminium ntsiab xws li npib tsib xee. Cov pa roj carbon hlau yog feem ntau tsim ntawm cov hlau thiab carbon, nrog qib tsawg kawg ntawm alloy ntsiab.
Kev Ua Txawv Sib Txawv
Stainless hlau muaj cov hlau ua kom tsis kam, thaum cov pa roj carbon hlau yog nquag los ua xeb hauv cov chaw noo noo. Stainless hlau feem ntau muaj qis dua lub zog thiab hardness dua li cov roj carbon hlau tab sis ua rau pom kev zoo dua thiab ductility.
Daim Ntawv Thov Kev Pab Cuam
Stainless hlau yog tsim rau ib puag ncig xav tau corrosion tsis kam, xws li kev ua zaub mov thiab khoom siv kho mob. Cov pa roj carbon hlau tau siv dav hauv cov txheej txheem txheej txheem, cov hlab ntsha siab, thiab lwm yam kev tiv thaiv uas muaj zog thiab xeb tuaj yeem ua tiav los ntawm kev pleev xim lossis lwm txoj kev.
