Stainless hlau yog tam sim no dav siv nyob rau hauv peb lub neej, xws li los ntawm aerospace khoom mus rau lub lauj kaub me me thiab lauj kaub, stainless hlau tuaj yeem pom nyob txhua qhov chaw. Txawm li cas los xij, muaj ntau pawg, thiab ntau tus phooj ywg muaj mob taub hau hauv kev xaiv. Piv txwv li, peb hom 304 stainless hlau thiab 316 stainless hlau, yog li hnub no Xiaorui yuav coj koj los nkag siab qhov txawv ntawm ob.
Qhov txawv ntawm 304 thiab 316
304 thiab 316 yog American Standards, 3 sawv cev rau 300 series steel, thiab ob tug lej kawg yog tus lej xov tooj. 304 Suav hom yog 06Cr19Ni9 (muaj tsawg dua 0.06 feem pua C, ntau dua 19 feem pua chromium, ntau dua 9 feem pua nickel); 316 Suav hom yog 06Cr17Ni12Mo2 (muaj tsawg dua 0.06 feem pua C, ntau dua 17 feem pua chromium, ntau dua 12 feem pua nickel, ntau dua 2 feem pua molybdenum).
Kuv ntseeg tias koj tuaj yeem pom los ntawm cov qib uas cov tshuaj muaj nyob hauv 304 thiab 316 sib txawv, thiab qhov sib txawv loj tshaj plaws los ntawm cov khoom sib txawv yog qhov sib txawv ntawm cov kua qaub thiab corrosion kuj. Piv nrog rau 304, 316 tau nce nickel Ni keeb, thiab ntxiv molybdenum Mo caij. Ntxiv npib tsib xee tuaj yeem txhim kho cov kav ntev, cov khoom siv kho tshuab, thiab oxidation tsis kam ntawm stainless hlau. Cov khoom molybdenum tuaj yeem txhim kho atmospheric corrosion, tshwj xeeb tshaj yog atmospheric corrosion uas muaj chloride. Yog li ntawd, ntxiv rau cov yam ntxwv ntawm kev ua tau zoo ntawm 304 stainless hlau, 316 stainless hlau kuj tseem tiv taus qhov tshwj xeeb nruab nrab corrosion, uas tuaj yeem txhim kho corrosion tsis kam rau tshuaj hydrochloric acid thiab dej hiav txwv, thiab txhim kho corrosion kuj rau brine halogen tov.
Daim ntawv thov ntau yam ntawm 304 thiab 316
304 stainless hlau yog dav siv, xws li cov tais diav hauv chav ua noj thiab cov tais diav, kho kom zoo nkauj architectural, zaub mov kev lag luam, kev ua liaj ua teb, nkoj qhov chaw, chav dej, qhov chaw pib thiab lwm yam.
Tus nqi ntawm 316 stainless hlau yog siab dua li ntawm 304. Piv nrog rau 304, 316 stainless hlau muaj zog acid kuj thiab zoo stability. 316 stainless hlau yog tsuas yog haum rau tshuaj, dyeing, ntawv, acetic acid, chiv thiab lwm yam khoom siv ntau lawm, khoom noj khoom haus kev lag luam thiab cov chaw nyob rau hauv ntug hiav txwv dej, thiab cov khoom uas muaj tshwj xeeb yuav tsum tau rau kev tiv thaiv intergranular corrosion.
Rau lub neej txhua hnub, 304 stainless hlau tuaj yeem ua tau raws li peb cov kev xav tau, thiab 304 kuj yog cov khoom siv hlau tsis muaj steel uas ua tau raws li cov qauv khoom noj.
