Duplex 2205 Tshuaj Muaj Hluav Taws Xob

Duplex 2205 Stainless hlau yog cov khoom siv muaj zog thiab ruaj khov uas ua ke ob hom steel: ferritic thiab ustenitic. Qhov kev sib xyaw no muab nws tseem tsis kam rau txoj kev xeb thiab lub zog, ua rau nws zoo rau cov muaj ib puag ncig nyuaj. Duplex 2205 yog ib qho kev hloov kho tshiab ntawm qhov ua tau ntawm S31803, hloov mus rau S32205 xyoo dhau los txhim kho kev txhim kho corrosion ntau dua. Stainless hlau 2205 Duplex yog dav siv nyob rau hauv kev lag luam li roj thiab roj, marine, thiab tshuaj lom neeg.

Hauv cov xov xwm no, peb yuav piav txog Duplex 2205 cov tshuaj muaj pes tsawg leeg thiab ua li cas nws ua rau nws muaj kev ua tau zoo.

Nkag Siab Duplex 2205 Tshuaj Siv Tshuaj
Duplex 2205 Stainless hlau yog ib cov khoom siv corrosion-resistant siv dav hauv kev lag luam uas yuav tsum muaj zog thiab kav dej thiab roj, thiab ua yeeb yam. 2205 Tshuaj lom neeg ua yeeb yam ua lub luag haujlwm tseem ceeb hauv nws cov kev ua tau zoo thiab cov khoom. Nws muab cov yam ntxwv zoo tshaj plaws ntawm ob qho tib si ferritic thiab ustenitic stainless hlau, muab nws qhov sib luag tshwj xeeb ntawm lub zog thiab kev tiv thaiv kom xeb thiab ua xeb.

Cov tshuaj lom neeg cov tshuaj lom neeg ntawm Ob 2205 feem ntau suav nrog:

Chromium (CR): 22-23%
Chromium yog qhov tseem ceeb hauv ob 2205, muab kev tiv thaiv corrosion zoo heev, tshwj xeeb rau pitting thiab crevice corrosion. Nws pab ua cov txheej tiv thaiv oxide rau ntawm cov hlau saum npoo av, txhim kho nws lub sijhawm ntev.
Nickel (NI): 4. {5-6. 5%
Npib tsib xee txhim kho cov hlau ua kom tsis kam rau corrosion thiab nce nws txoj kev nruj tiag, tshwj xeeb yog qhov kub tsawg. Txawm li cas los xij, qis dua cov ntsiab lus ntawm nroog npib qis dua hauv ob 2205 piv rau lwm cov neeg Austheritic ua rau nws tus nqi qis dua.
Molybdenum (mo): {3-3. 5%
Molybdenum txhim kho cov hlau ua kom tsis kam mus rau chloride kev ntxhov siab corrosion thiab pitting. Nws pab txhim kho cov ntaub ntawv kev ua tau zoo, xws li cov neeg muaj chlorides (piv txwv li, seawater).
Manganese (mn): 1. 5-2%
Manganese yog lub ntsiab lus tseem ceeb uas txhim kho cov hlau lub zog thiab kev ua haujlwm thiab pab tswj cov theem ua kom huv.
Nitrogen (n): {0. {08-0. 2%
Nitrogen tau nce lub zog ntawm Duplex 2205 thiab pab txhim kho nws txoj kev tiv thaiv nws txoj kev pitting thiab crevice corrosion. Nws tseem ua kom tau cov khoom siv tag nrho.
Hlau (FE): Tshuav
Hlau yog thawj feem ntawm Duplex 2205, ua kom muaj feem ntau ntawm cov alloy. Nws muab cov qauv kev kawm qib thiab lub moj khaum rau lwm cov ntsiab lus.
Lwm cov ntsiab lus:
Silicon (si): txog li 1%. Silicon pab txhawb rau cov hlau tiv thaiv mus rau oxidation thiab txhim kho nws lub zog tag nrho.
Cov pa roj carbon (c): siab tshaj 0. 03%. Cov ntsiab lus carbon yog khaws cia qis hauv Duplex 2205 los tiv thaiv qhov tsim ntawm carbides uas tuaj yeem txo nws txoj kev txhim kho corrosion.
Kev sib xyaw ua ke ntawm cov ntsiab lus muab rau duplex 2205 nws lub zog txawv: lub zog siab, weldability zoo, thiab zoo dua corrosion tsis kam. Cov khoom siv sib luag ua kom ntseeg tau cov khoom tuaj yeem tiv thaiv cov mob uas muaj kev nyuaj siab, thiab raug nws cov kev xaiv nrov rau cov ntawv thov.

Corrosion Kuj ntawm 2205 Duplex Stainless Hlau
2205 Duplex Stainless hlau muaj kev daws teeb meem zoo thiab ua tau zoo heev rau cov ntawv thov uas muaj cov tshuaj tiv thaiv chloride kev ntxhov siab. DuPleX 2205 chloride tsis muaj tshwm sim thaum tensile kev ntxhov siab tshwm sim rau cov hlau tsis muaj dej hauv ib puag ncig muaj cov neeg muaj kev kub ntxhov ntau dhau ntawm qhov kub muaj zog. Qhov tshwj xeeb ua ke ntawm chromium, molybdenum, thiab nitrogen nyob rau hauv 220 Nws cov ntawv sau siab tshaj yog muab ntau dua corrosion tsis kam muab piv rau cov siv tsis muaj zog 316L thiab 317L, kev ua tau zoo ntev rau kev lag luam uas xav tau kev lag luam muaj peev xwm ua kom muaj kev lag luam muaj peev xwm.
