Dab tsi yog qhov txawv ntawm stainless hlau 410 thiab 316?
Dab tsi yog qhov txawv ntawm stainless hlau 410 thiab 316?
410 stainless hlau yog martensitic stainless hlau uas muaj zog, siab hardness, magnetic zog, thiab yog cua sov{1}} kho. Nws yog haum rau cov cuab yeej thiab cutlery nyob rau hauv ib puag ncig me me. 316 stainless hlau yog austenitic stainless hlau nrog corrosion kuj zoo heev (tshwj xeeb tshaj yog tiv thaiv chlorides thiab nyob rau hauv marine ib puag ncig, ua tsaug rau nws cov ntsiab lus molybdenum), tsis yog - magnetic, thiab yog tsim rau tshuaj thiab marine engineering daim ntaub ntawv, tab sis nws kuj yog kim dua. Qhov sib txawv tseem ceeb ntawm ob yog tias 316 stainless hlau muaj superior corrosion kuj, thaum 410 stainless hlau muaj zog dua thiab hardness; Tsis tas li ntawd, 410 stainless hlau yog sib nqus, thaum 316 stainless hlau yog zoo li tsis yog{10}}magnetic.
Puas yuav cov hlau nplaum lo rau 316 stainless hlau?
316 stainless hlau feem ntau tsis yog- hlau nplaum vim nws yog austenitic stainless hlau. Txawm li cas los xij, tom qab cov txheej txheem xws li kev ua haujlwm txias (khoov, ncab, machining) lossis vuam, nws yuav dhau los ua hlau nplaum vim tias cov txheej txheem no tuaj yeem hloov qee cov austenite rau hauv magnetic martensite; los yog nws yog cam khwb cia (CF8M) thiab muaj ferrite, nws kuj yuav sib nqus. Yog li ntawd, thaum tsis ua tiav, mos 316 stainless hlau tsis yog -sib nqus, cov khoom xws li springs, hnyav tsim fasteners (bolts, txiv ntseej), los yog welded qhov chaw feem ntau muaj qee qhov kev sib nqus.
SS 410 yog dab tsi?
410 stainless hlau tuaj yeem ua kom tawv tawv los ntawm "quenching" kev kho cua sov, zoo ib yam li carbon steels feem ntau . 410 stainless hlau yog ib yam martensitic stainless hlau nrog cov ntsiab lus chromium tsawg kawg yog 11.5%, txaus los muab kev tiv thaiv corrosion. Cov khoom ua tau zoo tshaj plaws corrosion kuj tom qab polishing, quenching, thiab tempering. Cov qib stainless hlau no yog tsim rau cov ntawv thov uas yuav tsum muaj kev sib xyaw ua ke ntawm lub zog siab, nruab nrab kub tsis kam, thiab corrosion kuj.
SS 316 yog dab tsi?
Qhov tseem ceeb ntawm austenitic stainless hlau yog nyob rau hauv nqe lus txiav txim, nrog rau hom 304 stainless hlau yog qhov tseem ceeb tshaj plaws. Hom 316 stainless hlau yog tus qauv qib uas muaj molybdenum. Vim muaj cov molybdenum, Hom 316 stainless hlau tau zoo tag nrho cov corrosion kuj zoo dua li Hom 304 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv chloride- nplua nuj ib puag ncig, qhov uas nws exhibits superior tsis kam rau pitting thiab crevice corrosion. Nws muaj zoo heev formability thiab weldability. Nws tuaj yeem ua tau yooj yim stamped los yog dov rau hauv cov duab, tsim ntau qhov chaw siv hauv ntau yam xws li kev tsim kho, kev thauj mus los, thiab kev lag luam.

Corrosion Resistance
316 stainless hlau muaj kev tiv thaiv corrosion ntau dua li 410 stainless hlau, vim qhov sib ntxiv ntawm molybdenum hauv 316 alloy. Molybdenum txhim kho kev tiv thaiv chloride ion corrosion, uas tuaj yeem ua teeb meem hauv qee qhov chaw (xws li kev siv dej hiav txwv lossis ntug hiav txwv).
Machineability
Qhov sib txawv ntawm machinability ntawm 410 thiab 316 stainless hlau yog vim muaj cov pa roj carbon ntau dua ntawm 410 stainless hlau. Cov pa roj carbon monoxide ua tus neeg sawv cev tawv, ua rau 410 stainless hlau nyuaj rau tshuab dua 316 stainless hlau. Yog li, 410 stainless hlau feem ntau tsuas yog siv thaum machining ceev tsis yog qhov tseem ceeb.
