Cov yam ntxwv ntawm 304 cov kav hlau hlau thiab lawv cov ntawv thov
ASTM A312 kavPuas yog ntawm cov khoom siv dav tshaj plaws hauv kev lag luam ntau yam, tiv rau lawv cov khoom zoo nkauj thiab versatility. Ua los ntawm ib qho alloy muaj 18% chromium thiab 8% npib tsib xee, 304 stainless hlau tau cais raws li cov hlwv uas tsis siv. Hauv qab no, peb delve rau hauv cov yam ntxwv tseem ceeb ntawm 304 cov ntawv tseem ceeb thiab cov ntawv thov tshwj xeeb uas cov yam ntxwv tshwj xeeb tshaj plaws.
Cov yam ntxwv tseem ceeb ntawm 304 hlau kav
Corrosion Kuj
Ib qho tseem ceeb tshaj plaws ntawmATM A 312 304} Cov Yeeb Nkab Stainless Hlauyog lawv qhov tshwj xeeb tiv taus corrosion. Cov ntsiab lus chromium cov ntsiab lus ib txheej oxide ciav dej rau saum npoo av, tiv thaiv cov khoom ntawm xeb thiab oxidation. Qhov no ua rau 304 steel pipes zoo tagnrho rau kev siv nyob rau hauv cov chaw ib puag ncig raug rau cov dej noo, tshuaj lom neeg, thiab ntau yam mob acidic.
Lub zog thiab lub zog
304 Cov kav dej hlau muaj cov tshuab ua haujlwm zoo heev, ua rau lawv haum rau cov ntawv thov. Lawv tswj hwm lawv cov qauv kev ntseeg siab nyob rau hauv kev kub siab thiab ntsuas kub.
Kev tu cev thiab huv
Nrog ib tug du nto ua tiav,304 Cov Kav Hlau HlauCov kab mob kev loj hlob thiab yog ib qho yooj yim los ntxuav, kev sib ntsib nruj kev nyiam huv si. Qhov no yog qhov tshwj xeeb tshaj plaws hauv kev lag luam xws li kev ua zaub mov thiab chaw muag tshuaj.
Thaum Tshav Kub Kub Ua
304 Cov kav hlau hlau tuaj yeem tiv taus kub txog 870 degree (1598 degree f) tsis muaj kev sib cuam tshuam lawv cov khoom siv mechanical. Qhov kev tiv thaiv tshav kub no yog qhov tseem ceeb rau cov ntawv thov kev cuam tshuam nrog cov dej sov thiab roj av.
Formancion thiab Weldability
Tus qauv Austenitic ntawmSS 304 Yeeb Nkabmuab kev ua kom zoo nkauj thiab yooj yim ntawm fabrication. Cov kav dej no tuaj yeem khoov duav, welded, thiab tsim rau hauv ntau cov duab yam tsis tau poob lawv cov khoom.
Kev Thov Kom Zoo Nkauj
304 Stainless hlau muaj qhov kaj nrig thiab polished tsos, uas ntxiv rau kev ua kom zoo nkauj rau cov neeg ua lag luam thiab cov kev siv hniav.
Nqi zog-ua hauj lwm
Piv rau lwm qib ntawm{{0 {0}}. 4301 unic s30400 stainless hlau yeeb nkabMuaj kev ua kom pom kev sib npaug ntawm kev ua tau zoo thiab pheej yig, ua rau nws xaiv nrov hauv ntau qhov kev lag luam.
Cov Kev Siv ntawm 304 Cov Kav Hlau Hlau
Cov yam ntxwv saum toj no ua tau 304 cov kav hlau hlau ntau yam rau kev siv hla ntau cov haujlwm. Nov yog qee qhov kev siv tshwj xeeb:
Cov Khoom Noj Khoom Haus Thiab Dej Haus
ASME SA EK {0}}}} Cov Kav Hlau StainlessTau siv dav hauv cov zaub mov thiab dej haus kev lag luam rau kev thauj cov kua xws li mis nyuj, npias, thiab kua txiv. Lawv txoj kev tu huv thiab kev tiv thaiv kom corrosion ua kom muaj kev ncaj ncees ntawm cov khoom.
Kev Lag Luam
Lub corrosion tsis kam ntawm 304 stainless hlau ua rau nws haum rau kev tuav thiab thauj khoom ntau yam tshuaj, nrog rau cov kua qaub thiab alkalis.
Kev tsim kho thiab architecture
UNT tsis muaj cov kav hlauFeem ntau siv hauv kev ua lag luam niaj hnub no rau cov tsheb ciav hlau, txhua yam, thiab cov khoom zoo nkauj, tiv rau lawv cov kev thov kom zoo nkauj thiab kev ua kom zoo nkauj.
Kev lag luam kho mob thiab kev lag luam
Qhov huv thiab tiv taus cov kab mob ua tau 304 stainless kav kav tseem ceeb nyob rau hauv cov cuab yeej kho mob thiab cov khoom siv tshuaj.
Roj thiab Roj Kev Lag Luam
Vim lawv lub peev xwm los tiv thaiv ntau kub thiab ntsuas,ASTM A312 TPPUCKL ERW kavfeem ntau siv nyob rau hauv kev thauj cov roj av thiab cov nkev roj.
Kev Kho Mob Dej
304 Stainless hlau yog ib cov khoom siv tau yooj yim rau cov dej kho kom dej, raws li nws tiv thaiv corrosion hauv ob qho chaw tshiab thiab qab ntsev.
Automotive thiab Aerospace
Nyob rau hauv kev nqus cov tshuab nqus thiab tshuab hluav taws xob,304 Teem Sij Hawm 40 Seamless kavMuab lub zog thiab corrosion tsis xav tau rau kev ua tau ntev ntev.
Lub Zog Loj
Chav thiab roj turbine tshuab siv 304 hlau kav los ua kom muaj dej haus kub-kub.
Tag
304 Stainless Hlau KavUa ke lub zog, kav ruaj, thiab corrosion tsis kam nrog lub ntsej muag txaus nyiam, ua rau koj xaiv tau ntau yam rau ntau yam kev lag luam. Lawv cov kev ua tau zoo hauv ntau qhov chaw thiab cov kev mob kom ntseeg tau tias lawv nyob twj ywm lub pob kws muaj kev lag luam thiab cov ntawv thov kev lag luam.
