Yuav ua li cas ferritic stainless hlau cais?
Ferritic stainless hlau tuaj yeem muab faib ua ob pawg: zoo tib yam thiab high-purity ferrite raws li seb tag nrho cov pa roj carbon thiab nitrogen cov ntsiab lus tsawg dua 0.05%. Raws li cov ntsiab lus chromium, zoo tib yam ferritic stainless hlau yog subdivided rau hauv tsawg chromium, nruab nrab chromium thiab siab chromium ferritic stainless hlau.
Cov ntsiab lus chromium ntawm low-chromium ferritic stainless hlau yog feem ntau ntawm 10.5% thiab 14%. Nws muaj cov ntsiab lus chromium qis tshaj plaws ntawm tag nrho cov ferritic stainless hlau thiab tseem yog cov khoom pheej yig tshaj plaws. Hom stainless hlau no yog tsim rau siv nyob rau hauv me ntsis corrosive ib puag ncig los yog scenes uas tso cai rau xeb hauv zos. Piv txwv li, 409 yog tsim tshwj xeeb rau lub tsheb tso pa mufflers; 410L yog siv rau ntim thiab LCD zaub thav ntawv.
Cov ntsiab lus chromium ntawm nruab nrab-chromium ferritic stainless hlau yog nruab nrab ntawm 14% thiab 19%, thiab nws qhov kev ua tau zoo yog ze rau austenitic 304 stainless hlau. Nws yog cov khoom siv dav tshaj plaws hauv ferritic system. Vim nws cov ntsiab lus chromium siab thiab zoo heev corrosion kuj, 430 yog dav siv hauv tshuab ntxhua khaub ncaws, tshuab ntxhua khaub ncaws, cookers thiab khoom siv hauv chav ua noj. Nws yog qhov kev xaiv zoo tshaj rau cov khoom siv austenitic 304.
Cov ntsiab lus chromium ntawm high-chromium ferritic stainless hlau yog nruab nrab ntawm 19% thiab 30%. Los ntawm kev ntxiv cov ntsiab lus chromium thiab ntxiv molybdenum thiab lwm yam khoom, qhov kev tiv thaiv corrosion thiab oxidation kuj tau zoo tuaj. Hom stainless hlau no muaj qhov zoo dua austenitic 316 stainless hlau, yog li nws yog dav siv nyob rau hauv ntug dej hiav txwv cov tsev thiab corrosive ib puag ncig nrog cov ntsiab lus chlorine siab.
High-purity ferrite txhais tau hais tias tag nrho cov pa roj carbon thiab nitrogen cov ntsiab lus tsawg dua 0.05%. Nyob rau tib lub sijhawm, cov ntsiab lus xws li molybdenum, titanium, thiab niobium tau ntxiv los ua kom muaj kev tiv thaiv intergranular corrosion, pitting corrosion, crevice corrosion, thiab vuam kev ua tau zoo. Yog li ntawd, cov khoom siv no feem ntau yog siv rau hauv qhov cub microwave qhov cub, lub tank dej kub, lub hnub ci dej rhaub lossis hluav taws xob cov khoom siv hluav taws xob.
