1) Lub zog tawm los yog ntau dua li ob zaug uas zoo tib yam austenitic stainless hlau, thiab nws muaj qhov tsim nyog xav tau rau kev ua
Yas txaus. Phab ntsa tuab ntawm kev tso tsheb hlau luam lossis cov hlab siab ua los ntawm duplex stainless hlau yog 30-50% tsawg dua li ntawm feem ntau siv austenite, uas tau txais txiaj ntsig txo cov nqi.
2) Nws muaj qhov ua tau zoo tiv thaiv kev ntxhov siab corrosion cracking. Txawm tias cov duplex stainless hlau uas muaj cov ntsiab lus tsawg tshaj plaws muaj ntau dua qhov muaj peev xwm tiv thaiv kev ntxhov siab corrosion ntau dua li austenitic stainless hlau, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig muaj chloride ions. Kev nyuaj siab corrosion yog qhov teeb meem tseem ceeb uas nyuaj rau daws rau dog dig austenitic stainless hlau.
3) Qhov kev txhim kho corrosion ntawm 2205 duplex stainless hlau, uas feem ntau siv rau hauv ntau cov xov xwm, yog qhov zoo dua li qhov sib xws ntawm 316L austenitic stainless hlau, thaum super duplex stainless hlau muaj qhov zoo tshaj plaws corrosion tsis kam. Hauv qee qhov kev tawm xov xwm, xws li acetic acid thiab formic acid Nws tuaj yeem hloov lub high-alloy austenitic stainless hlau thiab txawm tias xeb-tiv thaiv alloys.
4) Nws muaj zoo hauv zos corrosion tsis kam. Piv nrog austenitic stainless hlau nrog tib cov ntsiab lus alloy, nws hnav corrosion tsis kam thiab qaug zog corrosion tsis kam yog qhov zoo dua li austenitic stainless hlau.
5) Cov coefficient ntawm linear nthuav dav qis dua li ntawm austenitic stainless hlau, uas yog ze rau ntawm cov hlau carbon. Nws yog tsim rau kev sib txuas nrog carbon hlau thiab muaj qhov tseem ceeb hauv kev tsim khoom, xws li kev tsim cov kab hlau sib txuas lossis cov kav hlau.
6) Txawm hais tias nyob rau hauv lub zog hloov kho lossis zoo li qub, nws muaj lub zog loj dua qhov muaj peev xwm tshaj li austenitic stainless hlau. Qhov no yog rau cov yam ntxwv kom tiv nrog cov xwm txheej ceev xws li kev sib tsoo thiab tawg. Duplex stainless hlau muaj cov cuab yeej zoo thiab muaj cov ntawv thov muaj txiaj ntsig.
