Hauv peb lub neej txhua hnub, cov khoom siv hlau tsis muaj hlau tuaj yeem pom nyob txhua qhov chaw. Los ntawm ntau yam khoom siv thiab cov khoom siv kho kom zoo nkauj hauv tsev, xws li qee yam khoom siv kho mob hauv tsev kho mob, kho kom zoo nkauj facade ntawm siab -nce vaj tse, tsheb of elevator, thiab lwm yam.; rau ntau yam khoom siv txhua hnub, xws li cov lauj kaub thiab lauj kaub hauv chav ua noj, cov txee, cov tais diav ntawm lub rooj noj mov, khob dej txhua hnub, thiab lwm yam, txhua tus muaj stainless hlau. Nws tuaj yeem hais tau tias cov hlau tsis muaj steel tau muab tso rau hauv txhua yam ntawm lub neej nrog nws qhov kev ua tau zoo tshwj xeeb thiab tau dhau los ua ib feem tseem ceeb ntawm peb lub neej.
Ntawm ntau hom stainless hlau, 304 thiab 316 stainless hlau yog qhov tshwj xeeb. Koj puas paub qhov txawv ntawm ob yam khoom no?
1. Cov khoom sib txawv
304 stainless hlau muaj 18% -20% chromium thiab 8% -10.5% npib tsib xee, thiab muaj lub zog zoo thiab oxidation tsis kam. Raws li lub hauv paus no, 316 stainless hlau ntxiv 2% -3% molybdenum, uas txhim kho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov tshuaj chlorine, tab sis muaj kev ua haujlwm tsis zoo.
2. Corrosion kuj
316 stainless hlau muaj 2.0-3.0% molybdenum, uas zoo dua li 304 stainless hlau hauv corrosion kuj. Tshwj xeeb tshaj yog nyob rau hauv cov dej ntsev thiab cov tshuaj chlorine siab, 316 tuaj yeem tiv taus corrosion zoo dua thiab tsim nyog rau cov chaw hauv hiav txwv, cov khoom siv tshuaj, thiab lwm yam . 304 yog ruaj txaus nyob rau hauv ib puag ncig, xws li khoom siv hauv tsev, kho kom zoo nkauj, thiab lwm yam.
3. Mechanical zog
304 stainless hlau muaj zog dua me ntsis thiab hardness, thiab yog haum rau lub tsev cov qauv uas dais siab . 316 muaj zoo ductility thiab tensile lub zog, thiab yog haum rau kev kho mob, precision qhov chaw, thiab lwm yam. Tsis tas li ntawd, nyob rau hauv ib puag ncig kub, 316 yog ruaj khov thiab tsis yooj yim rau soften los yog poob zog.
4. Nqe sib txawv
Kev lag luam tus nqi ntawm 304 stainless hlau yog li 15,000-20,000 yuan / ton. 316 muaj molybdenum, yog li tus nqi siab dua, txog 20,000 yuan / tuj, uas yog tsim rau cov xwm txheej uas muaj kev tiv thaiv corrosion siab.
5. Daim ntawv thov teb
304 yog tsim rau txhua hnub chav ua noj, tableware, kho kom zoo nkauj architectural, thiab lwm yam .; 316 yog siv ntau dua hauv cov khoom siv kho mob, khoom noj khoom haus, kev lag luam marine thiab tshuaj lom neeg.
Txhawm rau sau cov ntsiab lus saum toj no: yog tias koj tsom mus rau kev lag luam, 304 tuaj yeem ua tau raws li cov kev xav tau dav dav; Yog hais tias ib puag ncig yog corrosive heev los yog muaj kev xav tau siab rau kev ua haujlwm ntev, 316 yog qhov kev xaiv zoo dua.
