2205 Stainless hlau Phaj Duplex steel phaj
Kev piav qhia
Kev ntxhov siab corrosion kuj ntawm 2205 (00Cr22Ni5Mo3N) duplex stainless hlau hauv nruab nrab chloride tov thiab H2S yog zoo dua li ntawm 304L, 316L austenitic stainless hlau thiab 18-5Mo duplex stainless hlau.Yuav ua tau txias, kub ua thiab tsim, zoo weldability, cov hlau yog haum rau cov khoom siv, yog tam sim no lub ntiaj teb no nyob rau hauv lub dual-theem stainless hlau siv nyob rau hauv ntau qib.
2205 stainless hlau phaj (00Cr22Ni5Mo3N) duplex stainless hlau yog tsim los ntawm 21% chromium, 2.5% molybdenum thiab 4.5% nickel-nitrogen alloy.Nws muaj lub zog siab, zoo cuam tshuam toughness thiab zoo ib yam thiab hauv zos kev nyuaj siab corrosion kuj.Lub zog tawm los ntawm 2205 duplex stainless hlau yog ob zaug ntawm austenitic stainless hlau.Cov cuab yeej no tso cai rau cov neeg tsim qauv kom txo qhov hnyav thaum tsim cov khoom, ua rau cov hlau no pheej yig dua li 316,317L.Cov hlau no tshwj xeeb tshaj yog siv rau hauv qhov kub ntawm -50 ° F / + 600 ° F.Cov ntawv thov dhau qhov ntsuas kub no kuj tseem yuav xav txog cov hlau no, tab sis muaj qee qhov kev txwv, tshwj xeeb tshaj yog thaum siv rau cov qauv welded.
2205 (00Cr22Ni5Mo3N) Duplex Stainless hlau nta
1. Piv nrog 316L thiab 317L austenitic stainless hlau, 2205 alloy muaj kev ua tau zoo dua hauv kev tiv thaiv corrosion thiab tawg corrosion, nws muaj corrosion kuj siab, piv nrog austenite, nws thermal expansion coefficient qis dua, thermal conductivity ntau dua.
2. Piv nrog austenitic stainless hlau, lub zog compressive ntawm duplex 2205 stainless hlau phaj yog ob zaug ntawm austenitic stainless hlau.Piv nrog 316L thiab 317L, tus tsim qauv tuaj yeem txo nws qhov hnyav.Lub 2205 alloy yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv lub - 50 ° F / + 600 ° F qhov kub thiab txias txawm nyob rau hauv nruj kev txwv (tshwj xeeb tshaj yog rau welded lug).
2205 (00Cr22Ni5Mo3N) Corrosion Resistance
1. Uniform corrosion
Vim yog cov ntsiab lus chromium (22%), molybdenum cov ntsiab lus (3%) thiab nitrogen cov ntsiab lus (0.18%), corrosion kuj ntawm 2205 yog superior rau 316L thiab 317L nyob rau hauv feem ntau ib puag ncig.
2. Local corrosion kuj
Cov ntsiab lus ntawm chromium, molybdenum thiab nitrogen hauv dual-theem steel 2205 ua rau nws tiv taus qhov chaw thiab qhov sib txawv corrosion hauv oxidizing thiab acidic daws.
3. Kev ntxhov siab corrosion kuj
Lub duplex microstructure ntawm stainless hlau yog pab los txhim kho lub cracking kuj ntawm stainless hlau.Chloride stress corrosion tshwm sim nyob rau hauv austenitic stainless hlau ntawm ib tug tej yam kub, nro, oxygen thiab chloride muaj.Vim tias cov xwm txheej no nyuaj rau kev tswj hwm, kev siv 304L, 316L thiab 317L raug txwv hauv qhov kev hwm no.
4. Anti-corrosion qaug zog
Lub zog siab thiab corrosion kuj ntawm duplex steel 2205 ua rau nws muaj zog corrosion siab zog.Cov cuab yeej ua haujlwm raug cuam tshuam rau qhov chaw corrosive thiab thauj mus los, thiab 2205 nta yog qhov zoo tagnrho rau cov ntawv thov.
2205 (00Cr22Ni5Mo3N) Kev siv
