ferritic stainless hlau yog dab tsi?

Stainless hlau yog cov khoom siv dav siv uas tau dhau los ua cov khoom tseem ceeb hauv ntau yam kev lag luam los ntawm kev tsim kho mus rau kev kho mob. Tab sis koj puas paub tias tsis yog tag nrho cov hlau tsis muaj hlau tsim sib npaug? Ib hom sawv tawm rau nws cov yam ntxwv tshwj xeeb thiab kev siv: ferritic stainless hlau. Hauv no blog ncej, peb yuav delve rau hauv qhov sib txawv ntawm ferritic stainless hlau thiab lwm yam hom stainless hlau, nws qhov zoo thiab qhov tsis zoo, thiab yuav ua li cas kom raug vuam nws. Yog li zaum rov qab thiab npaj txhij mus kawm cov khoom zoo kawg nkaus ntawm ferritic stainless hlau.

Dab tsi yog stainless hlau?

Stainless hlau yog ib qho alloy uas muaj tsawg kawg yog 10.5% chromium los ntawm huab hwm coj, uas muab nws cov khoom tshwj xeeb. Chromium tsim ib txheej nyias ntawm oxide nyob rau saum npoo ntawm stainless hlau, tiv thaiv nws los ntawm corrosion thiab muab nws tsis kam mus staining, xeb, thiab discoloration.

Tab sis vim li cas qhov no tseem ceeb? Lub durability ntawm stainless hlau ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv siv rau ntau yam kev nyiam huv thiab huv si yog ib qho tseem ceeb, xws li cov zaub mov ua zaub mov los yog tsev kho mob. Tsis tas li ntawd, qhov zoo nkauj thiab corrosion kuj ntawm stainless hlau ua rau nws nrov nyob rau hauv architectural designs xws li niaj hnub vaj tse los yog choj.

Muaj ntau hom stainless hlau muaj nyob rau hauv kev ua lag luam niaj hnub no, muaj ntau yam sib txawv uas cuam tshuam rau lawv cov kev ua tau zoo tag nrho. Qee qhov piv txwv suav nrog austenitic stainless hlau (feem ntau), ferritic stainless hlau (uas peb yuav tsom mus rau tom qab), martensitic stainless hlau, duplex stainless hlau, thiab nag lossis daus-hardening stainless hlau.

Kev nkag siab txog qhov muaj pes tsawg leeg ntawm txhua hom stainless hlau tuaj yeem pab koj xaiv cov khoom siv raws li cov kev thov tshwj xeeb thaum ua kom lub neej ntev thiab kev ntseeg tau.

Ntau hom Stainless Hlau

Vim nws zoo heev corrosion kuj, durability, thiab zoo nkauj, stainless hlau yog ib tug dav siv thiab nrov khoom nyob rau hauv ntau yam industries. Raws li cov tshuaj muaj pes tsawg leeg uas cuam tshuam rau nws cov kev ua tau zoo, muaj ntau hom stainless hlau.

Austenitic stainless hlau yog hom ntau tshaj plaws, muaj ntau cov nickel thiab chromium. Nws muaj lub zog zoo, toughness, thiab ductility tab sis tuaj yeem kim.

Ferritic stainless hlau muaj cov ntsiab lus nickel qis dua li austenitic tab sis siab dua chromium cov ntsiab lus. Nws yog hlau nplaum thiab muaj kev tiv thaiv corrosion zoo tab sis tsis tawv li austenitic.

Martensitic stainless hlau muaj cov ntsiab lus siab carbon nrog cov nickel thiab chromium nruab nrab. Nws muaj lub zog siab tab sis qis dua corrosion kuj.

Duplex stainless hlau muaj qhov sib xyaw microstructure ntawm ferrite thiab austenite theem, nrog cov ntsiab lus chromium ntau dua li lwm hom. Lawv muab lub zog zoo, toughness, thiab corrosion kuj ntawm tus nqi tsim nyog.

Precipitation-hardening (PH) stainless hlau muaj cov alloys tshwj xeeb uas tuaj yeem ua kom tawv nqaij los ntawm kev kho cua sov kom muaj zog thaum tswj tau zoo corrosion.

Hauv cov ntsiab lus, nkag siab txog ntau hom stainless hlau muaj nyob rau hauv qhov tseem ceeb rau kev xaiv cov khoom siv raws li koj qhov kev thov tshwj xeeb.

ferritic stainless hlau yog dab tsi?

Ferritic stainless hlau yog ib hom stainless hlau uas feem ntau muaj chromium thiab ib qho me me ntawm carbon thiab lwm yam khoom. Nws muaj cov khoom sib nqus thiab muaj kev tiv thaiv corrosion siab, ua rau nws zoo rau ntau yam kev siv xws li tsheb tso tsheb, khoom siv hauv tsev, thiab tsev cladding.

Ib qho ntawm qhov zoo ntawm ferritic stainless hlau yog nws zoo heev kub-kub oxidation tsis kam. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov ntawv thov uas xav tias yuav raug kub hnyiab, xws li cookware los yog industrial ncu.

Piv nrog rau lwm hom stainless hlau xws li austenitic lossis martensitic stainless hlau, kev siv ferritic stainless hlau muaj lwm qhov zoo dua vim tias cov ntsiab lus qis nickel xav tau rau kev tsim khoom, ua rau cov nqi qis dua. Qhov no ua rau lawv pheej yig dua yam tsis muaj kev cuam tshuam kev ua haujlwm.

Txawm li cas los xij, txawm tias nws muaj ntau yam zoo, ferritic stainless hlau kuj muaj qee qhov tsis zoo. Ib qho teeb meem loj yog tias nws tsis tuaj yeem hardened los ntawm kev kho cua sov, uas txwv tsis pub nws siv hauv qee yam kev siv uas yuav tsum tau muaj zog dua.

Thaum welding ferritic stainless hlau, preheating yuav tsum tau xav txog, raws li ceev ceev los ntawm vuam kub yuav ua rau embrittlement.

Ferritic stainless hlau tseem nrov vim nws qhov sib npaug ntawm kev ua tau zoo thiab kev pheej yig.

Qhov zoo thiab qhov tsis zoo ntawm Ferritic Stainless Steel

Ferritic stainless hlau muaj ntau qhov zoo, ua rau nws muaj kev xaiv nrov hauv ntau yam lag luam. Ib qho ntawm nws cov txiaj ntsig tseem ceeb yog nws qhov kev tiv thaiv corrosion thiab kub-kub oxidation, ua rau nws zoo heev rau siv nyob rau hauv ib puag ncig raug rau corrosive ntsiab.

Piv rau lwm hom stainless hlau, ferritic stainless hlau kuj muaj qhov zoo ntawm cov nqi-zoo. Nws kuj muaj cov khoom sib nqus zoo, ua rau nws tsim nyog rau kev siv tshwj xeeb xws li tshuab electromagnetic.

Txawm li cas los xij, ferritic stainless hlau kuj muaj qee qhov tsis zoo. Nws tuaj yeem nyuaj rau vuam vim muaj kev pheej hmoo ntawm kev nkag siab thiab tawg. Tsis tas li ntawd, qhov toughness ntawm hom hlau no feem ntau qis dua li ntawm austenitic steel, ua rau nws tsis tshua muaj zog nyob rau hauv tej yam kev mob loading.

Tsis tas li ntawd, ferritic stainless hlau tuaj yeem ua nkig ntawm qhov kub thiab txias, ua rau nws tsis haum rau kev siv txias. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm hais tias ferritic stainless hlau muaj ntau qhov zoo, kev nkag siab txog nws cov kev txwv yog qhov tseem ceeb thaum txiav txim siab nws siv rau txhua daim ntawv thov lossis qhov project uas yuav tsum tau ua kom muaj kev ruaj ntseg thiab kev ua haujlwm zoo.

Vuam txoj kev rau Ferritic Stainless hlau

Vim lub siab nyiam ntawm ferritic stainless hlau kom tawg thaum vuam, ua tiav vuam cov khoom no ua rau muaj kev sib tw. Nov yog qee cov lus qhia txog yuav ua li cas ua tau zoo weld ferritic stainless hlau:

Ua ntej, preheating cov khoom ua ntej vuam yog qhov tseem ceeb. Cov txheej txheem no pab txo qhov kev pheej hmoo ntawm kev tawg los ntawm kev ua kom txias txias thiab txo qis thermal kev nyuaj siab tom qab vuam. Qhov yuav tsum tau preheat kub nyob ntawm qhov tuab thiab qib ntawm cov khoom raug welded.

Qhov thib ob, xaiv txoj cai muab tub lim yog qhov tseem ceeb heev. Ferritic stainless hlau muaj lub siab loj hlob zoo, uas cuam tshuam tsis zoo rau nws cov khoom siv kho tshuab. Siv cov xaim hluav taws xob qis qis nrog titanium lossis niobium tuaj yeem pab txo qis kev loj hlob thiab txhim kho corrosion kuj.

Thib peb, ua tib zoo saib xyuas qhov tsim nyog thaum vuam, xws li tswj cov cua sov thiab tsis txhob kub dhau, tuaj yeem txo qhov deformation.

Nyob ntawm daim ntawv thov lossis kev siv ntawm cov khoom siv welded ua los ntawm ferritic stainless hlau, kev kho cua sov tom qab vuam (PWHT) kuj yuav tsum tau.

Kev npaj kom zoo ua ntej vuam ua ke nrog kev ua tib zoo xaiv cov hlau muab tub lim thiab kev tswj xyuas thaum lub sij hawm vuam yuav ua kom muaj kev vam meej thaum ua hauj lwm nrog ferritic stainless hlau cov ntaub ntawv.
