S32205 Khoom Khoom
ASTM A240 / A240M-01 Duplex stainless hlau 2205 alloy yog duplex stainless hlau muaj li ntawm 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 ntxhov siab corrosion kuj.Lub zog tawm los ntawm 2205 duplex stainless hlau yog ntau tshaj ob npaug ntawm cov hlau tsis zoo austenitic.Qhov tshwj xeeb no tso cai rau cov neeg tsim qauv kom txo qhov hnyav thaum tsim cov khoom, ua rau cov hlau no pheej yig dua li 316 thiab 317L.Cov hlau no tshwj xeeb tshaj yog siv rau hauv qhov kub ntawm -50 ° F / + 600 ° F.Rau cov ntawv thov sab nraud 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.
Qhov zoo ntawm S32205 Duplex Steel
1.Lub zog tawm los yog ntau tshaj ob npaug ntawm cov hlau tsis zoo austenitic, thiab nws muaj qhov tsim nyog tsim nyog.
Plasticity txaus.Cov phab ntsa tuab ntawm cov tso tsheb hlau luam lossis cov hlab ntsha siab ua los ntawm duplex stainless hlau yog 30-50% qis dua li cov khoom siv feem ntau siv austenite, uas yog qhov tsim nyog los txo cov nqi.
2.Nws muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking.Txawm hais tias duplex stainless hlau nrog cov ntsiab lus qis tshaj plaws muaj qhov ua haujlwm siab dua rau kev ntxhov siab corrosion tawg dua li austenitic stainless hlau, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride ions.Kev ntxhov siab corrosion yog ib qho teeb meem tseem ceeb uas zoo tib yam austenitic stainless hlau nyuaj los daws.
3.Qhov corrosion kuj ntawm cov feem ntau siv 2205 duplex stainless hlau nyob rau hauv ntau yam xov xwm yog zoo dua li ntawm zoo tib yam 316L austenitic stainless hlau, thaum lub super duplex stainless hlau muaj heev corrosion kuj, thiab nyob rau hauv ib co xov xwm, xws li acetic acid, formic acid Nws tuaj yeem hloov siab-alloy austenitic stainless hlau, thiab txawm tias corrosion-resistant alloys.
4. Nws muaj qhov zoo hauv zos corrosion kuj.Piv nrog austenitic stainless hlau nrog sib npaug cov ntsiab lus alloy, nws hnav corrosion kuj thiab qaug zog corrosion kuj zoo dua li austenitic stainless hlau.
5. Lub coefficient ntawm linear expansion yog qis dua li ntawm austenitic stainless hlau, uas yog ze rau ntawm cov hlau.Nws yog qhov tsim nyog rau kev sib txuas nrog cov pa roj carbon steel thiab muaj qhov tseem ceeb hauv engineering, xws li kev tsim cov phaj sib xyaw lossis cov hauv ob sab phlu.
6. Txawm hais tias nyob rau hauv dynamic load lossis static load, nws muaj peev xwm nqus tau ntau dua li austenitic stainless hlau, uas muaj cov txiaj ntsig zoo rau cov khoom siv los tiv thaiv cov xwm txheej tam sim no xws li kev sib tsoo, tawg, thiab lwm yam, thiab muaj cov txiaj ntsig siv tau.
