Corrosion Kuj & Ib puag ncig ruaj khov ntawm SS304 VS SS316 Stainless Hlau Hlau Mesh

1. Pib

Corrosion yog ib qho tseem ceeb tshaj plaws sib txawvSS304thiabSS316 Stainless Hlau Hlau Mesh. Ob qib kawm yog Austenitic thiab tsim cov yeeb yaj kiab passive ntawm chromium oxide (cr₂o₃), tsis tau ntxiv ntawmMolybdenum (mo)Hauv SS316 dastically txhim kho nws lub peev xwm tiv nrog kev nqus ib puag ncig.

Hlau hlau yog qhov tshwj xeeb rau kev xeb vim nws cov npoo siab}}}}} Txawm tias cov pits me me lossis cov pob txha me tuaj yeem ua rau muaj kev tsis ua haujlwm, cuam tshuam kev ncaj ncees kev ncaj ncees, kev siv tau, thiab kev nyab xeeb.

Tshooj lus no muab cov ncauj lus piav qhia ntxaws ntawm SS304 thiab SS316 ntawm:

2. Corrosion mechanisms nyob rau hauvStainless Hlau Hlau Mesh

Nkag siab corrosion pib nrog lubPassive TxheejCov. Lub chromium {- cov txheej nplua nuj tiv thaiv cov hlau, tab sis cov pej xeem muaj peev xwm cuam tshuam nws.

2.1 Hom corrosion cuam tshuam rau cov mesh mesh

2.2 Pitting tiv taus tus lej sib npaug (pren)

Pren kwv yees ib qho tsis muaj cov hlau tsis xeb tsis kam mus rau chloride -}} induced pitting:

Qhov sib ntxiv ntawm Molybdenum nce pren, ua ss316 deb tiv taus hauvTubrog nkoj, brine, lossis acidic ib puag ncig.

3. Ib puag ncig kev ua yeeb yam sib piv

Hlau Mesh ntsib ntau hom kev sib txawv:

3.1 Tub Rog & Nqaum Qhov Raug

Piv txwv li:Nqaum cov tsheb nqaj hlau ua los ntawm SS304 pom tias xeb stainfleing tsis pub dhau 18 lub hlis, hos 316 cov tsheb nqaj hlau tau kav ntev dua ib xyoo caum.

3.2 Kev Lag Luam & Tshuaj Ib puag ncig

SS316 yog txuam nrog tiv thaiv:

Hydrochloric acid vapors

Tus mos

Nitric thiab acetic acids

Chloride - Kev nplua nuj ntxuav tshuaj

Daim Ntawv Thov:Tshuaj Nroj Tsuag thiab Mesh raug ua rau muaj kev phom sij cuam tshuam los ntawm SS316 kom tsis txhob hloov cov khoom.

3.3 Kev Siv Khoom Ua Noj Ua Noj

Khoom noj khoom noj - kev ib puag ncig muaj peev xwm sib txawv tuaj yeem sib txawv:

Salted nqaij ntses

Cov Tso Tsheb Hlau Vawj

Acidic txiv ntoo kua txiv ua kua

High - kub ntxuav mus ncig

SS304 ua haujlwm rauqhuav, tsawg - kua zaub cov khoom noj kua qaub, tab sisSS316 yog qhov tseem ceeb rau brine lossis acid -} nplua nuj txheej txheem.

3.4 Nyob Sab Nraud Kws Muaj Khoom

Kev nthuav dav ib puag ncig rau cov ntsej muag, fencing, lossis vaj tse vaj tswv kos duab:

316 cov descable recability txo tau ntev-} Lub neej tu thiab txuas ntxiv kev pabcuam lub neej.

4. Weld point corrosion

Welded Hlau Mesh yog tshwj xeeb tshaj yog siv rau kev xeb vim tias:

Thaum tshav kub kub -} cuam tshuam zones (Haz) poob qee cov chromium, txo cov passivation

Weld Seams tuaj yeem nkag ya raws thiab paug

Engineering Acensight:Rau welded mesh raug rau chloride,316L tau pom zoo kom pom tseeb.

5. Kev ntxhov siab - corrosion tsoo

SCC tshwm sim thaum stainless hlau hauv qab tensile kev ntxhov siab yog nthuav tawm ib puag ncig ib puag ncig:

SS304 yog ib nrab kev ua tau

SS316 muaj ntau dua npib tsib xee thiab molybdenum cov ntsiab lus → ntau ntxiv resistant

Piv txwv li:Zoo mesh hauv marine tshuaj cog khoom cog khoom siv nrog 304 xaim ua tsis tiav vim SCC; SS316 hloov xyoo dhau los yam tsis muaj kev ua tsis tiav.

6. Tiag -} ntiaj teb kev kawm

6.1 nqaij ntses hiav txwv

Qhov Teeb Meem: SS304 mesh siv hauv brine tso tsheb hlau luam corroded tsis pub dhau 14 lub hlis.

Daws: hloov nrog SS316, nthuav dav lub neej ua hauj lwm rautshaj 9 xyoos.

Qhov tshwm sim: txo qis qis, tsawg dua kev hloov pauv, thiab kev nyiam huv.

6.2 Nqaum Ruaj Ntseg Mesh

Qhov Teeb Meem: SS304 Hlau Mesh fencing tsim los pitting thiab xeb stains hauv 18 lub hlis.

Kev daws: SS316 welded mesh ntsia.

Qhov txiaj ntsig: tswj cov qauv txheej txheem kev ntseeg siab rau ntau dua kaum xyoo.

6.3 Kev lim tshuaj lom neeg mesh

SS304 mesh raug rau hydrochloric acid vapors corroded sai sai.

SS316 Mesh qhia tau cov siab tsis kam thiab kev saib xyuas txij nkawm tsawg.

7. Qhov kub cuam tshuam rau corrosion

Ntsiab lus tseem ceeb:Kev kub siab rau cov tshuaj pleev xim chaw; SS316 Foostiv cov kub siab dua + chloride sib xyaw ua ke zoo dua.

8. Kev tu thiab tu qhov cuam tshuam

Kev tu huv yog qhov tseem ceeb hauv cov zaub mov, tshuaj, thiab kev lag luam tshuaj lom neeg. Compatibility nrog cov neeg sawv cev huv:

Kev siv:Xaiv SS316 txo cov kev saib xyuas txij nkawm thiab txhim kho kev ua raws huv.

9. Daim Ntawv Qhia Xaiv Ib Lub Neej

10. Xaus

SS304yog haum rauNyob sab hauv tsev, qhuav, me me, lossis nyiaj txiag -} rhiab cov ntawv thov.

SS316yog qhov tseem ceeb rauharsh, chloride-rich, chemical, marine, or high-sanitization environments.

Xaiv txoj cai alloy thiaj li ua kom ntev zog, txo kev txij nkawm, thiab ua haujlwm ntau dua.

Rau welded hlau mesh,316L feem ntau nyiamRau chloride kis lossis zaub mov - kev siv.

Corrosion Kuj yogIb tus neeg sib txawv tshaj plawsnruab nrab ntawm cov alloys. Nkag siab ib puag ncig cov kev mob thiab kev tu huv yog qhov tseem ceeb rau xaiv cov qauv zoo tshaj plaws ntawm cov hlau.
