Duplex 2507 Txheej txheem cej luam
Duplex 2507 yog super duplex stainless hlau tsim rau cov ntawv thov uas xav tau tshwj xeeb lub zog thiab corrosion kuj. Alloy 2507 muaj 25% chromium, 4% molybdenum, thiab 7% npib tsib xee. Qhov siab molybdenum, chromium thiab nitrogen cov ntsiab lus ua rau muaj kev tiv thaiv zoo heev rau chloride pitting thiab crevice corrosion nres thiab cov qauv duplex muab 2507 nrog tshwj xeeb tsis kam rau chloride kev nyuaj siab corrosion cracking.
Kev siv Duplex 2507 yuav tsum txwv rau cov ntawv thov qis dua 600 ° F (316 ° C). Kev nthuav dav ntawm qhov kub thiab txias tuaj yeem txo qhov toughness thiab corrosion kuj ntawm alloy 2507.
Duplex 2507 muaj cov khoom siv zoo heev. Feem ntau lub teeb ntsuas ntawm 2507 cov khoom siv tuaj yeem siv los ua kom tiav tib lub zog tsim ntawm cov hlau npib tsib xee tuab. Cov txiaj ntsig kev txuag hauv qhov hnyav tuaj yeem txo tus nqi tag nrho ntawm fabrication.
Corrosion Resistance
2507 Duplex yog ib qho kev tiv thaiv zoo heev rau kev xeb los ntawm cov organic acids xws li formic thiab acetic acid. Nws kuj tseem tiv taus cov inorganic acids, tshwj xeeb tshaj yog tias lawv muaj chlorides. Alloy 2507 yog heev resistant rau carbide-txog intergranular corrosion. Vim lub ferritic feem ntawm cov duplex qauv ntawm cov hlau nws yog heev resistant rau kev nyuaj siab corrosion cracking nyob rau hauv sov chloride uas muaj ib puag ncig. Los ntawm kev ntxiv ntawm chromium, molybdenum thiab nitrogen localized corrosion xws li pitting thiab crevice nres yog txhim kho. Alloy 2507 muaj qhov zoo heev hauv zos pitting kuj.
Dab tsi yog cov yam ntxwv ntawm Duplex 2507?
● Siab tsis kam rau chloride kev nyuaj siab corrosion cracking
