Feem ntau ntawm cov stainless hlau strips muag hauv khw yog cov khoom tiav, thiab cov khoom zoo stainless hlau kuj tuaj yeem ua rau stainless hlau strips tom qab machining thiab hardening. Cov khoom no muaj kev ua tau zoo heev thiab siv nyob rau hauv ntau qhov chaw. Stainless hlau muaj zoo weldability, zoo heev hnav tsis kam thiab oxidation kuj. Cov hlau nplaum ua tiav stainless hlau sawb kuj muaj cov hlau nplaum zoo permeability.
Cov yam ntxwv zoo ntawm stainless hlau sawb feem ntau tshwm sim nyob rau hauv peb yam: tensile lub zog, thermal conductivity thiab expansion coefficient. Lub zog tensile ntawm stainless hlau strips nrog kev ua tau zoo yog siab dua 520, thiab cov thermal conductivity txawv raws li cov txheej txheem kev ua haujlwm sib txawv, tab sis lawv tag nrho cov concentrated ntawm 20 thiab 500. Cov expansion coefficient yog tus nqi uas feem ntau txhawj xeeb. thaum siv stainless hlau sawb. Lub expansion coefficient ntawm cov khoom zoo heev yog nyob nruab nrab ntawm 20 thiab 400. Tsis tas li ntawd, lub melting point thiab resistivity ntawm stainless hlau sawb kuj tseem ceeb cov ntaub ntawv qhia rau nws kev ua tau zoo. Feem ntau, cov khoom uas muaj kev ua tau zoo heev muaj kev tiv thaiv ntawm 0.73 ohms thiab melting point ntawm 1300 txog 1400 degrees Celsius.
Nyob rau hauv qhov tseeb, cov high-kev ua tau zoo alloy steels uas yuav ua tau rau hauv stainless hlau strips tam sim no muaj zoo heev corrosion kuj thiab nto aesthetics. Nws nto muaj chromium zaj duab xis, uas tuaj yeem cais cov huab cua thiab tiv thaiv cov pa oxygen los ntawm corroding steel sawb.
Yog vim li cas vim li cas stainless hlau strips tsis tshua muaj corrosive yog tias chromium feem ntau ntxiv rau cov hlau siv los tsim cov hlau tsis muaj steel, thiab nws cov ntsiab lus yuav tsum siab tshaj 12 feem pua. Nws yog precisely vim hais tias ntawm qhov sib ntxiv ntawm chromium hais tias cov khoom nto ntawm steel sawb yog qualitatively txhim kho. Cov hlau muaj ob hom kev kho mob kub kub thiab kev kho kom txias dua, thiab muaj qhov ntau dua, muaj zog tshwj xeeb, muaj zog tshwj xeeb muaj peev xwm ua kom sov thiab muaj kuab yas. Txoj siv hlau no tau siv dav hauv aviation, navigation, kev tsim kho, machining thiab lwm yam.
