2205 Duplex Stainless hlau yog ib nitrogen -}}} Txiaj Ntsig Chav Hlau Stainless. Duplex Stainless Hlau 2205 alloy yog ib qho kev sib xyaw ua ke stainless hlau muaj txog 21% chromium, 2.5% molybdenum thiab 4.5% nickel {}} nitrogen alloy. Nws txoj kev tawm tsam rau pitting thiab crevice corrosion tshwj xeeb yog qhov tshwj xeeb hauv ib puag ncig muaj chlorides. Nws tau yeej qhov kev haum ntawm cov neeg siv nrog nws cov neeg ua haujlwm siab dua thiab tau ua cov ntaub ntawv txhim kho txhim kho uas txuag ob qho hnyav thiab kev nqis peev.

Piv nrog ustenitic stainless hlau, qhov zoo ntawm duplex stainless hlau yog li hauv qab no:
1. Cov paib lub zog yog ntau tshaj li ob zaug uas feem ntau ntawm cov hlau tsis muaj zog, thiab nws muaj cov yas huv txaus thiab tawv uas yuav tsum muaj rau kev sib sau. Lub phab ntsa tuab ntawm kev tso tsheb hlau luam lossis cov hlab ntsha siab ua los ntawm cov yas stlex stainless hlau yog 30-50% tsawg dua li cov hlau uas nquag siv, uas yog qhov ua kom txo tau txo qis.
2.Nws tau muaj kev tsis kam ua kom ntxhov siab. Txawm hais tias lub duplex stainless hlau nrog qis tshaj Alloy cov ntsiab lus muaj qhov siab dua cov hlau uas muaj cov hlau tsis muaj mob chloride, tshwj xeeb tshaj yog nyob rau ib puag ncig muaj chloride ions. Kev ntxhov siab corrosion yog ib qho teeb meem tseem ceeb uas nyuaj los daws rau cov hlau tsis muaj zog.
3.Qhov corrosion tsis kam ntawm 2205 duplex stainless hlau, uas feem ntau siv nyob rau hauv ntau cov xov xwm, yog zoo dua rau tias ntawm dog dig 316l austenitic steel. Super Duplex Stainless hlau tau muaj kev kub siab heev thiab tuaj yeem hloov siab {{{{} {ove {{5 {5 {
4.Nws tau txais kev tiv thaiv zoo rau hauv kev ua kom huv si corrosion. Piv nrog ustenitic steel hlau ntawm cov ntsiab lus zoo sib xws alloy, nws tsis kam mus hnav corrosion thiab qaug zog corrosion thiab rog corrosion yog zoo dua rau ntawm cov hlau unylal.
5.Qhov linear nthuav coefficient ntawm Austenitic Stainless hlau yog tsawg thiab ze rau cov tshuaj carbon hlau, ua rau nws haum rau kev txuas nrog cov hlau. Qhov no muaj cov engineering tseem ceeb, xws li hauv kev tsim cov phiaj lossis cov ntaub qhwv.
6.Whethethethethete nyob rau hauv dynamic lossis zoo li qub load xwm txheej, ob lub stainless hlau muaj lub peev xwm nqus lub peev xwm ntau dua li cov hlwv me me. Qhov no yog qhov ua tau zoo rau cov qauv txheej txheem hauv kev cuam tshuam nrog cov xwm txheej tam sim ntawd xws li tawg thiab tawg, thiab nws muaj cov ntawv thov ua kom zoo.
Daim ntawv thov ntawm 2205 khoom siv:
205 Duplex Stainless hlau stainless hlau yog dav siv nyob rau hauv: nruab nrab kev lag luam, tshuaj ntsuam kev lag luam, kev lag luam kev lag luam, kev lag luam teeb pom kev lag luam rau cov khoom noj thiab cov tshuaj lag luam.
