Duplex stainless hlau 2205 tus naj npawb txheem: ASTM A240 / A240M - 01 duplex stainless hlau 2205 alloy yog duplex stainless hlau muaj li 22% chromium, 2.5% molybdenum thiab 4.5% nickel-nitrogen alloy. Nws muaj lub zog siab, zoo cuam tshuam toughness thiab zoo tag nrho thiab hauv zos kev nyuaj siab corrosion kuj.
Cov zis muaj zog ntawm 2205 duplex stainless hlau yog ntau dua ob zaug uas zoo tib yam austenitic stainless hlau. Cov yam ntxwv no ua rau cov neeg tsim qauv ua kom hnyav dua thaum tsim cov khoom lag luam, ua cov alloy no raug nqi ntau dua li 316 thiab 317L. Cov alloy no yog tsim tshwj xeeb rau qhov kub ntawm -50 ° F / +600 ° F. Rau cov ntawv thov dhau ntawm qhov ntsuas kub, qhov alloy no tseem tuaj yeem xav tau, tab sis muaj qee qhov kev txwv, tshwj xeeb tshaj yog thaum ua ntawv thov rau cov txheej txheem welded.
Vessels Cov hlab ntsha siab, lub taub tso kua cia siab, cov raj xa dej siab siab, cov cua sov sib hloov (kev lag luam ua tshuaj lom neeg).
Cov roj thiab cov kav xa dej, cov khoom siv ua kom sov.
Kev lim dej ua haujlwm.
If Cov ntawv lag luam pulp thiab ntawv lag luam, cov khoom siv tshuaj dawb, ntim khoom thiab txheej txheem.
Fts Cov qij teb qeeb mentshis, nias qaws, hniav tawg, cuam tshuam, thiab lwm yam hauv qab qhov chaw siab thiab muaj peev xwm tiv tau xeb.
Thauj lub thawv ntawm nkoj lossis tsheb thauj khoom
1. Piv nrog 316L thiab 317L austenitic stainless hlau, duplex stainless hlau 2205 alloy muaj kev ua tau zoo dua hauv kev tiv taus pitting corrosion thiab crevice corrosion. Nws muaj kev tiv thaiv zoo corrosion. Piv nrog austenite, nws Cov coefficient ntawm thermal expansion qis dua thiab thermal conductivity siab dua.
2. Piv nrog austenitic stainless hlau, duplex stainless hlau 2205 alloy muaj ob zaug nws lub zog compressive. Piv nrog 316L thiab 317L, tus tsim qauv tuaj yeem txo nws qhov hnyav. Alloy 2205 tshwj xeeb tshaj yog haum rau qhov kub ntawm -50 ° F / +600 ° F. Nyob rau hauv qhov kev txwv nruj (tshwj xeeb tshaj yog rau cov qauv sib txuas ua ke), nws kuj tseem tuaj yeem siv qhov kub tsawg dua.
