Duplex 2507 Txheej txheem cej luam
Duplex 2507 yog ib qho super duplex stainless hlau tsim rau cov ntawv thov uas xav tau qhov tshwj xeeb ntawm lub zog thiab kev txhim kho corrosion. Alloy 2507 muaj 25% chromium, 4% molybdenum, thiab 7% npib tsib xee. Qhov no siab molybdenum, chromium thiab nitrogen cov ntsiab lus yog qhov ua tau zoo rau chloride pitting thiab crevice corrosion nres thiab cov duplex qauv muab 2507 nrog tshwj xeeb tsis kam rau chloride kev nyuaj siab corrosion tawg.
Kev Siv Duplex 2507 yuav tsum txwv rau kev thov hauv qab 600 ° F (316 ° C). Ncua kom qhov kub siab ntxiv tuaj yeem txo qhov ob qho tawv thiab xeb ntawm alloy 2507.
Ob Lub Tsev 2507 muaj cov yam ntxwv zoo heev rau lub cev. Feem ntau lub teeb ntsuas ntawm 2507 cov khoom siv tuaj yeem siv kom ua tiav qhov qauv tsim kom zoo ib yam ntawm cov roj hluav taws xob nickel tuab. Qhov txiaj ntsig ntawm qhov hnyav nyob hauv hnyav tuaj yeem txo tus nqi tag nrho ntawm kev tsim tawm.
Corrosion kuj
2507 Duplex muaj cov tshuaj tiv thaiv corrosion los ntawm cov organic acids xws li formic thiab acetic acid. Nws tseem yog tiv dhau cov inorganic acids, tshwj xeeb yog tias lawv muaj chlorides. Alloy 2507 muaj qhov cuam tshuam zoo rau carbide-cuam tshuam intergranular corrosion. Vim yog qhov chaw ua haujlwm ferritic ntawm duplex tus qauv ntawm cov alloy nws tiv taus kev ntxhov siab corrosion cracking hauv chloride sov uas muaj qhov chaw kawm. Los ntawm kev sib ntxiv ntawm cov chromium, molybdenum thiab nitrogen hauv thaj chaw xeb xws li pitting thiab crevice nres tau zoo tuaj. Alloy 2507 tau zoo kawg hauv zos pitting kuj.
Dab tsi yog cov yam ntxwv ntawm Duplex 2507?
• Muaj peev xwm tiv taus chloride kev nyuaj siab corrosion cracking
• Lub Zog Muaj Zog
• Cov tshuaj tiv thaiv zoo dua rau chloride pitting thiab cov xeb xeb
• Zoo dav corrosion kuj
• Pom zoo rau kev thov txog 600
• Qis tsawg ntawm kev siv thermal
• Ua ke ntawm cov khoom muab los ntawm austenitic thiab ferritic qauv
• Zoo weldability thiab ua haujlwm tau
