Duplex Stainless hlau 2205 Castings

2205 duplex stainless hlau yog duplex stainless hlau muaj li ntawm 21% chromium, 2.5% molybdenum thiab 4.5% nickel-nitrogen alloy. Cov ferrite thiab austenite tsim txhua tus account rau kwv yees li 50%. Nws muaj lub zog siab, zoo cuam tshuam toughness thiab zoo tag nrho thiab hauv zos kev ntxhov siab corrosion kuj. Lub zog tawm los ntawm 2205 duplex stainless hlau yog ob zaug ntawmaustenitic stainless hlau. Cov yam ntxwv no ua rau cov neeg tsim qauv txo qhov hnyav thaum tsim cov khoom lag luam, ua rau cov hlau no siv nyiaj ntau dua li 316 thiab 317L. Cov hlau no tshwj xeeb tshaj yog haum rau qhov kub ntawm -50 ° F / + 600 ° F. Rau cov ntawv thov dhau qhov ntsuas kub no, cov hlau no kuj tuaj yeem txiav txim siab, tab sis muaj qee qhov kev txwv, tshwj xeeb tshaj yog thaum siv rau cov qauv welded.

Corrosion Resistance thiab Siv Ib puag ncig:
Piv nrog 316L thiab 317L austenitic stainless hlau, 2205 duplex stainless hlau muaj kev ua tau zoo tshaj plaws hauv kev tiv thaiv pitting corrosion thiab crevice corrosion. Nws muaj siab corrosion kuj. Piv nrog rau austenitic, nws cov coefficient ntawm thermal expansion yog qis dua thiab thermal conductivity yog siab dua. Piv nrog austenitic stainless hlau, duplex stainless hlau 2205 alloy muaj ob zaug nws compressive zog. Piv nrog 316L thiab 317L, tus tsim qauv tuaj yeem txo nws qhov hnyav. Alloy 2205 yog tshwj xeeb tshaj yog haum rau qhov kub ntawm -50 ° F / + 600 ° F. Raws li kev txwv nruj (tshwj xeeb tshaj yog rau cov qauv welded), nws kuj tuaj yeem siv rau qhov kub thiab txias.
