Customized 304 304L Stainless Hlau Phaj
Feature ntawm stainless hlau phaj
1. Weldability
Cov khoom siv sib txawv muaj cov kev xav tau sib txawv rau kev ua haujlwm vuam.Ib chav kawm ntawm tableware feem ntau tsis xav tau kev ua haujlwm vuam, thiab txawm tias suav nrog qee lub lag luam lauj kaub.Txawm li cas los xij, cov khoom lag luam feem ntau xav tau kev ua haujlwm zoo ntawm cov khoom siv raw, xws li cov khoom siv hauv chav kawm thib ob, lub khob thermos, cov kav dej steel, lub tshuab rhaub dej, cov khoom siv dej, thiab lwm yam.
2. Corrosion kuj
Cov khoom siv stainless hlau feem ntau yuav tsum muaj kev tiv thaiv corrosion zoo, xws li Chav Kawm I thiab II cov tais diav, cov tais diav hauv chav ua noj, lub tshuab rhaub dej, cov khoom siv dej, thiab lwm yam. Qee cov tub lag luam txawv teb chaws kuj ua cov tshuaj tiv thaiv corrosion ntawm cov khoom: siv NACL aqueous tov kom sov nws mus rau boiling, thiab ncuav nws tom qab ib lub sijhawm.Tshem tawm cov tshuaj, ntxuav thiab qhuav, thiab ntsuas qhov hnyav los txiav txim siab txog qib ntawm corrosion (Ceeb toom: Thaum cov khoom polished, Fe cov ntsiab lus hauv daim ntaub abrasive lossis ntawv xuab zeb yuav ua rau xeb ntawm qhov chaw thaum lub sij hawm kuaj).
3. Polishing kev ua tau zoo
Nyob rau hauv lub neej niaj hnub no, stainless hlau cov khoom yog feem ntau polished thaum lub sij hawm tsim khoom, thiab tsuas yog ob peb yam khoom xws li dej rhaub thiab dej dispenser liner tsis xav tau polishing.Yog li ntawd, qhov no yuav tsum tau hais tias polishing kev ua tau zoo ntawm raw khoom yog zoo heev.Cov yam tseem ceeb uas cuam tshuam rau kev ua haujlwm polishing yog raws li hauv qab no:
(1) deg defects ntawm raw khoom.Xws li khawb, pitting, pickling, thiab lwm yam.
(2) Qhov teeb meem ntawm cov khoom siv raw.Yog hais tias lub hardness tsawg dhau lawm, nws yuav tsis yooj yim rau polish thaum polishing (cov cuab yeej BQ tsis zoo), thiab yog tias qhov hardness tsawg dhau, qhov tshwm sim ntawm cov txiv kab ntxwv tev yog ib qho yooj yim los tshwm rau saum npoo thaum lub sij hawm sib sib zog nqus nqus, yog li cuam tshuam. cov cuab yeej BQ.BQ khoom nrog siab hardness kuj zoo.
(3) Rau cov khoom sib sib zog nqus, cov pob me me dub thiab RIDGING yuav tshwm sim rau ntawm qhov chaw ntawm qhov chaw nrog ntau qhov deformation, yog li cuam tshuam rau BQ kev ua haujlwm.
4. Thaum tshav kub kub tsis kam
Thaum tshav kub kub tsis kam txhais tau hais tias stainless hlau tseem tuaj yeem tswj nws lub cev zoo thiab cov khoom siv kho tshuab ntawm qhov kub thiab txias.
Cov txiaj ntsig ntawm cov pa roj carbon: Cov pa roj carbon zoo tsim thiab ruaj khov hauv austenitic stainless hlau.Cov ntsiab lus uas txiav txim siab austenite thiab nthuav dav thaj av austenite.Lub peev xwm ntawm carbon los tsim austenite yog kwv yees li 30 npaug ntawm cov npib tsib xee, thiab cov pa roj carbon monoxide yog cov khoom sib txuas uas tuaj yeem ua kom muaj zog ntawm austenitic stainless hlau los ntawm cov khoom siv ntxiv zog.Cov pa roj carbon kuj tuaj yeem txhim kho qhov kev ntxhov siab corrosion tsis kam ntawm austenitic stainless hlau hauv cov tshuaj chloride siab heev (xws li 42% MgCl2 boiling tov).
Txawm li cas los xij, hauv austenitic stainless hlau, carbon feem ntau suav tias yog cov khoom tsis zoo, feem ntau vim tias nyob rau hauv qee qhov xwm txheej (xws li vuam lossis cua sov ntawm 450 ~ 850 ° C) hauv cov hlau tsis muaj corrosion, carbon tuaj yeem cuam tshuam nrog cov pa roj carbon monoxide. hlau.Chromium tsim high-chromium Cr23C6-hom carbon tebchaw, uas ua rau depletion ntawm lub zos chromium, uas txo cov corrosion kuj ntawm hlau, tshwj xeeb tshaj yog tsis kam mus rau intergranular corrosion.yog li ntawd.Feem ntau ntawm cov tshiab tsim chromium-nickel austenitic stainless hlau txij li xyoo 1960 yog cov roj carbon tsawg uas muaj cov ntsiab lus tsawg dua 0.03% lossis 0.02%.Nws tuaj yeem paub tias vim tias cov ntsiab lus carbon tsawg zuj zus, qhov cuam tshuam ntawm intergranular corrosion ntawm cov hlau txo.Thaum cov ntsiab lus carbon qis dua 0.02% muaj cov txiaj ntsig pom tseeb tshaj plaws, thiab qee qhov kev sim kuj tau taw qhia tias carbon kuj nce pitting corrosion nyiam ntawm chromium austenitic stainless hlau.Vim tias muaj kev phom sij ntawm cov pa roj carbon monoxide, tsis yog tsuas yog cov ntsiab lus carbon yuav tsum tau tswj kom tsawg li sai tau hauv cov txheej txheem smelting ntawm austenitic stainless hlau, tab sis kuj nyob rau hauv cov txheej txheem tom ntej ntawm kub, txias ua hauj lwm thiab kev kho cua sov kom tsis txhob muaj cov pa roj carbon ntau ntxiv. nto ntawm stainless hlau thiab tsis txhob chromium carbides Precipitate.
5. Corrosion kuj
Thaum tus nqi ntawm chromium atoms nyob rau hauv cov hlau tsis tsawg tshaj li 12.5%, cov electrode muaj peev xwm ntawm cov hlau tuaj yeem hloov tam sim ntawd los ntawm qhov tsis zoo rau qhov zoo electrode.Tiv thaiv electrochemical corrosion.
Execution standard ntawm stainless hlau phaj
Stainless hlau phaj muaj ib tug du nto, siab plasticity, toughness thiab mechanical zog, thiab yog resistant rau corrosion los ntawm acids, alkaline gases, kev daws teeb meem thiab lwm yam xov xwm.Nws yog cov hlau alloy uas tsis xeb yooj yim, tab sis tsis muaj xeb kiag li.Stainless hlau phaj hais txog lub phaj hlau uas tiv taus corrosion los ntawm cov xov xwm tsis muaj zog xws li cua, chav dej thiab dej, thaum acid-resistant steel phaj hais txog cov hlau phaj uas tiv taus corrosion los ntawm chemically corrosive media xws li kua qaub, alkali, thiab ntsev.Stainless hlau phaj tau nyob ib ncig ntawm ntau tshaj li ib puas xyoo txij li thaum nws tawm thaum pib ntawm lub xyoo pua 20th.
Stainless hlau phaj feem ntau yog ib lo lus dav dav rau stainless hlau phaj thiab acid-resistant steel phaj.Taw qhia thaum pib ntawm lub xyoo pua no, txoj kev loj hlob ntawm stainless hlau phaj tau tso ib qho tseem ceeb ntawm cov khoom siv thiab cov txheej txheem rau kev txhim kho kev lag luam niaj hnub thiab kev tshawb fawb thiab thev naus laus zis.Muaj ntau ntau hom stainless hlau phaj nrog cov khoom sib txawv.Nws tau maj mam tsim ntau pawg hauv txoj kev txhim kho.
Raws li cov qauv, nws tau muab faib ua plaub pawg: austenitic stainless hlau, martensitic stainless hlau (xws li nag lossis daus hardening stainless hlau), ferritic stainless hlau, thiab austenitic ntxiv rau ferritic duplex stainless hlau.Cov tshuaj lom neeg muaj pes tsawg leeg lossis qee cov yam ntxwv hauv cov phaj hlau tau muab faib ua chromium stainless hlau phaj, chromium nickel stainless hlau phaj, chromium nickel molybdenum stainless hlau phaj, qis carbon stainless hlau phaj, siab molybdenum stainless hlau phaj, siab purity stainless hlau phaj. , lwm.
Raws li cov yam ntxwv ntawm kev ua tau zoo thiab kev siv cov hlau phaj, nws tau muab faib ua nitric acid-resistant stainless hlau daim hlau, sulfuric acid-resistant stainless hlau daim hlau, pitting-resistant stainless hlau daim hlau, kev nyuaj siab corrosion-resistant stainless hlau daim hlau, thiab lub zog siab. stainless hlau phaj.Raws li cov yam ntxwv ua haujlwm ntawm cov hlau phaj, nws tau muab faib ua qhov kub tsis tshua muaj steel hlau phaj, tsis muaj hlau nplaum stainless hlau phaj, pub dawb-txiav stainless hlau phaj, superplastic stainless hlau phaj, thiab lwm yam. Cov txheej txheem siv feem ntau yog faib raws li rau cov yam ntxwv ntawm cov hlau phaj, cov tshuaj lom neeg muaj pes tsawg leeg ntawm steel phaj thiab kev sib xyaw ua ke ntawm ob.
Feem ntau muab faib ua martensitic stainless hlau, ferritic stainless hlau, austenitic stainless hlau, duplex stainless hlau thiab nag lossis daus hardening stainless hlau, thiab lwm yam los yog muab faib ua ob pawg: chromium stainless hlau thiab nickel stainless hlau.Kev siv ntau yam Kev siv: cov khoom siv pulp thiab ntawv cov khoom siv hluav taws xob sib hloov, cov khoom siv kho tshuab, cov khoom siv dyeing, cov khoom siv ua yeeb yaj kiab, cov kav dej, cov khoom siv sab nrauv rau cov tsev nyob hauv ntug dej hiav txwv, thiab lwm yam.
Stainless hlau phaj muaj ib tug du nto, siab plasticity, toughness thiab mechanical zog, thiab yog resistant rau corrosion los ntawm acids, alkaline gases, kev daws teeb meem thiab lwm yam xov xwm.Nws yog cov hlau alloy uas tsis xeb yooj yim, tab sis tsis muaj xeb kiag li.
Ko taw thickness thiab txheem thickness ntawm stainless hlau phaj
Ko taw thickness txhais tau hais tias qhov tseeb thickness tsis ntau txawv los ntawm theoretical thickness (tseem hu ua daim ntawv thickness), uas yog me me tsis zoo sib txawv.Yog tias daim ntawv thickness yog 1.0MM, qhov dav dav yuav tsum tau ko taw tuab yog tsawg kawg yog 0.98MM-1.0MM, thiab ko taw tuab tuaj yeem nkag siab tias "thick txaus", thiab tus qauv thickness yog qhov theoretical thickness.Cov coils ntawm cov hlau zeb tau sau npe thaum lawv tawm hauv lub Hoobkas, qhia txog qhov kev xav ntawm qhov tuab.Qhov no yog tus qauv thickness.
