Dab tsi yog qhov tshwj xeeb ntawm Duplex Stainless Steel?
Dab tsi tshwj xeeb ntawm duplex stainless hlau yog tias nws muab cov txiaj ntsig zoo ntawm ferritic thiab austenitic stainless hlau, uas ua rau muaj qhov tshwj xeeb ntawm kev ua tau zoo. Cov ntsiab lus yog raws li nram no:
Cov khoom siv zoo heev: Duplex stainless hlau muaj cov yas zoo dua thiab tawv dua li cov hlau tsis muaj ferritic, uas tso cai rau lawv ua kom muaj kev ruaj khov zoo dua thaum tiv taus kev cuam tshuam thiab siab. Nyob rau tib lub sijhawm, lawv tsis muaj teeb meem ntawm chav tsev kub brittleness, uas txhais tau hais tias cov khoom yuav tsis tawg vim brittleness ntawm ib txwm siv kub. Zoo corrosion kuj: Vim nws qhov tshwj xeeb ob-theem qauv, duplex stainless hlau muaj kev ua haujlwm zoo rau ntau qhov chaw corrosive, nrog rau pitting corrosion. Qhov no corrosion kuj ua rau duplex stainless hlau haum rau siv nyob rau hauv hnyav ib puag ncig xws li tshuaj ua thiab marine daim ntaub ntawv. Txuag cov peev txheej: Duplex stainless hlau yog npib tsib xee-txuag stainless hlau, uas txhais tau hais tias kev siv cov khoom siv kim kim xws li npib tsib xee tuaj yeem txo tau zoo thaum lub sijhawm tsim khoom, yog li txo cov nqi thiab txhim kho cov txiaj ntsig kev lag luam ntawm cov khoom siv. Kev ua haujlwm vuam zoo: Duplex stainless hlau muaj kev ua haujlwm vuam zoo, tab sis nws yuav tsum tau muab sau tseg tias cov khoom siv hluav taws xob yuav tsum tau tswj xyuas thaum lub vuam txheej txheem los tiv thaiv kev ua haujlwm tsis zoo hauv thaj chaw kub. High thermal conductivity: Piv nrog cov ntshiab austenitic stainless hlau, duplex stainless hlau muaj cov thermal conductivity ntau dua, uas pab txhim kho kev sib hloov hluav taws xob. Superplasticity: Nyob rau hauv tej yam kev mob, duplex stainless steels muaj peev xwm nthuav tawm superplasticity, uas tso cai rau lawv siv nyob rau hauv complex txheej txheem xws li sib sib zog nqus nqus los yog stamping.
