Super Duplex Alloy 2507 Yeeb Nkab(UNS S32750/1.4501) yog dav siv nyob rau hauv ib puag ncig muaj kev muaj thaj chaw ib puag ncig vim nws cov kws kho zoo heev thiab corrosion tsis kam. Cov khoom no belongs rau lub cim thib ob ntawm cov hlau duplex stainless. Los ntawm kev ntsuas microstructure ntawm Austenite thiab ferrite (li 50% txhua), nws muaj qhov zoo txhim kho lub peev xwm los tiv thaiv corrosion thiab kev ntxhov siab corrosion.
Tshuaj lom neeg muaj pes tsawg leeg ntawmASME SA790 S32750 YEEB
Cov tshuaj lom neeg cov tshuaj lom neeg tsim qauv ntawm S3275 {4 4}} yog cov cim los ntawm kev sib dhos siab, muaj tsib xee, 4% molybdenum thiab 0.3% nitrogen. Lub synergistic nyhuv ntawm chromium thiab molybdenum muab nws zoo tshaj plaws chloride tsis tsuas yog txhim kho lub zog ntawm cov khoom siv, tab sis kuj txhawb kev ruaj ntseg ntawm lub austenite theem.
Cov Khoom Siv Neeg Kho Tshuab ntawmSuper Duplex S32750
Raws li ATTM A790 thiab ASME SA789 cov qauv khoom siv ntawm S32750 suav ntau dua lossis sib npaug nrog 550 MPa, thiab elongation ntau dua lossis sib npaug rau 15%. Nws lub zog yog ntau dua ob zaug uas ntawm cov pa roj tsis huv stainless hlau (xws li 304/316), thaum ua kom muaj kev tswj hwm kom zoo.
Corrosion tsis kam ntawm alloy 2507 raj
S32750 kav dej tau zoo nyob rau hauv ib puag ncig muaj chloride ions, hydrogen sulfide lossis cov kua qaub tsis muaj zog. Piv txwv li, hauv cov dej txias, subswine roj thiab roj rauv roj (FGD) thiab cov tshuaj tiv thaiv roj (FGD) thiab cov tshuaj tiv thaiv tshuaj lom neeg
