Ua ntej tshaj plaws, cia peb tham txog dab tsi stainless hlau yog. Nws yog hais txog cov hlau uas tiv taus corrosion hauv huab cua thiab tsis muaj zog corrosive media. Yog tias tus nqi corrosion tsawg dua {{0}}.01mm / xyoo, nws raug suav hais tias yog "tuaj yeem tiv taus corrosion"; Yog tias tus nqi corrosion tsawg dua 0.1 hli / xyoo, nws raug suav tias yog "corrosion resistant".
Stainless hlau qauv nyob rau hauv Suav teb yog sawv cev los ntawm cov cim cim ntxiv rau cov lej, xws li: 1Cr18Ni9, 0Cr18Ni9, 00Cr18Ni9, 1Cr17, 3Cr13, 1Cr17Mn6Ni5N, thiab lwm yam. Cov lej sawv cev rau cov ntsiab lus sib thooj.
Cov qauv stainless hlau feem ntau sawv cev los ntawm cov cim digital, suav nrog 200 series, 300 series, thiab 400 series, uas yog cov qauv kev sawv cev ntawm Tebchaws Meskas, xws li 201, 202, 302, 303, 304, 316, 410, 420, 430, thiab lwm yam. Lub koom haum American Iron thiab Steel yog Siv peb tus lej los xaiv ntau hom qauv ntawm malleable stainless hlau. hauv:
① Austenitic stainless hlau yog cim nrog cov lej ntawm 200 thiab 300 series.
② Ferritic thiab martensitic stainless hlau yog sawv cev los ntawm cov lej hauv 400 series. Piv txwv li, qee qhov ntau ntawm austenitic stainless hlau raug xaiv 201, 304, 316 thiab 310.
③ Cov ferritic stainless hlau yog cim nrog 430 thiab 446, thiab martensitic stainless hlau yog cim nrog 410, 420 thiab 440C, duplex (austenite-ferrite).
④ Stainless hlau, nag lossis daus hardening stainless hlau thiab siab alloys nrog cov ntsiab lus hlau tsawg dua 50 feem pua yog feem ntau muaj npe los ntawm cov npe patent lossis cov cim lag luam.
Functional sib txawv:
304 yog cov khoom siv ntau yam thiab dav siv stainless hlau, uas yog dav siv los ua cov cuab yeej thiab cov khoom uas yuav tsum tau muaj cov khoom zoo (corrosion resistance and formability). Tiv thaiv cov xeb hauv kev tsim kho, tiv thaiv kev tawm tsam los ntawm kev ua zaub mov (tab sis tej zaum yuav corrode ntawm qhov kub siab uas muaj cov kua qaub thiab chlorides), thiab tiv thaiv cov organic tebchaw, dyes, thiab ntau yam inorganic compounds. 304L hom (tsawg carbon), zoo tiv thaiv nitric acid, thiab ruaj rau nruab nrab kub thiab concentration ntawm sulfuric acid, dav siv los ua kua roj cia tank, siv raws li cov khoom kub kub (304N), cov khoom siv thiab lwm yam khoom siv, khoom siv hauv chav ua noj, Cov khoom siv hauv tsev kho mob, cov cuab yeej thauj mus los, cov chaw kho dej khib nyiab.
Hom 430 muaj cov ntsiab lus qis dua li Hom 304 thiab yog siv rau kev ua kom zoo nkauj zoo nkauj hauv cov huab cua me me, nrog rau nitric acid thiab cov khoom siv ua zaub mov.
Qhov txawv ntawm stainless hlau 201 thiab 304:
1. Specifications: Feem ntau siv stainless hlau muab faib ua ob hom: 201 thiab 304. Qhov tseeb muaj pes tsawg leeg yog txawv. 304 yog qhov zoo dua, tab sis kim, thiab 201 yog qhov phem dua.
2. Cov muaj pes tsawg leeg ntawm 201 yog 17Cr-4.5Ni-6Mn-N, uas yog qib Ni steel thiab lwm yam rau 301 steel. Nws yog hlau nplaum tom qab ua haujlwm txias thiab siv hauv tsheb ciav hlau.
3. Cov muaj pes tsawg leeg ntawm 304 yog 18Cr-8Ni, uas yog cov feem ntau siv stainless hlau thiab kub-resistant hlau. Siv rau hauv cov khoom siv khoom noj khoom haus, khoom siv tshuaj lom neeg Xitong, nuclear zog, thiab lwm yam.
4. 201 yog siab manganese, qhov saum npoo yog ci heev nrog tsaus thiab ci, thiab siab manganese yog yooj yim rau xeb. 304 muaj ntau cov chromium, thiab qhov saum npoo yog matte thiab tsis xeb. Ob leeg muab piv ua ke. Qhov tseem ceeb tshaj plaws yog qhov kev tiv thaiv corrosion txawv. Kev tiv thaiv corrosion ntawm 201 yog qhov tsis zoo, yog li tus nqi pheej yig dua. Thiab vim tias 201 muaj cov npib tsib xee tsawg, tus nqi qis dua li ntawm 304, yog li qhov corrosion kuj tsis zoo li ntawm 304.
5. Qhov txawv ntawm 201 thiab 304 yog cov ntsiab lus nickel. Thiab tus nqi ntawm 304 yog kim dua tam sim no, tab sis 304 tsawg kawg tuaj yeem lav tias nws yuav tsis xeb thaum siv. (Cov tshuaj tuaj yeem siv rau kev sim)
6. Stainless hlau tsis yooj yim rau xeb vim tias chromium-nplua nuj oxides yog tsim rau saum npoo ntawm lub cev steel los tiv thaiv lub cev hlau. 201 khoom belongs rau high manganese stainless hlau, uas yog siab dua nyob rau hauv hardness, siab dua nyob rau hauv carbon thiab qis nyob rau hauv nickel tshaj 304.
