Los ntawm muaj pes tsawg leeg rau daim ntawv, ntau yam cuam tshuam rau cov yam ntxwv ntawm cov khoom siv hlau stainless. Ib qho kev txiav txim siab tseem ceeb tshaj plaws yog qib twg ntawm cov hlau siv. Qhov no yuav txiav txim siab txog ntau yam ntawm cov yam ntxwv thiab, thaum kawg, tus nqi thiab lub neej ntawm koj cov khoom siv stainless hlau.
Yog li koj paub yuav pib qhov twg?
Txawm hais tias txhua daim ntawv thov tshwj xeeb, 7 cov lus nug no qhia txog cov kev xav tseem ceeb los pab koj txo qis koj cov kev xaiv thiab nrhiav cov qhab nia zoo tshaj plaws rau koj cov kev xav tau lossis daim ntawv thov.
1. KOJ YUAV TSUM TAU TXAIS STEEL LI CAS?
Thaum koj xav txog cov hlau tsis muaj steel, thawj yam uas los rau hauv lub siab yog tej zaum tsis kam rau cov kua qaub thiab chlorides - xws li cov khoom siv hauv kev lag luam lossis thaj chaw marine. Txawm li cas los xij, qhov ntsuas kub tsis kam yog qhov tseem ceeb rau kev xav thiab.
Yog tias koj xav tau kev tiv thaiv corrosion, koj yuav xav kom tsis txhob ferritic thiab martensitic steels. Cov qib stainless hlau zoo tagnrho rau corrosive ib puag ncig muaj xws li austenitic lossis duplex alloys xws li qib 304, 304L, 316, 316L, 2205, thiab 904L.
Rau qhov chaw kub kub, cov qib austenitic feem ntau yog qhov zoo tshaj plaws. Nrhiav qib siab nrog chromium, silicon, nitrogen, thiab lub ntiaj teb tsis tshua muaj cov ntsiab lus yuav ua rau cov hlau muaj peev xwm tiv taus qhov kub thiab txias. Cov qhab nia zoo rau qhov chaw kub kub muaj xws li 310, S30815, thiab 446.
Austenitic steel qib kuj yog qhov zoo tagnrho rau qhov kub thiab txias lossis qhov chaw txias. Rau kev tiv thaiv ntxiv, koj tuaj yeem saib cov qib qis carbon lossis siab nitrogen. Cov qib sib piv rau qhov chaw kub qis muaj xws li 304, 304LN, 310, 316, thiab 904L.
2. Puas yog kuv cov hlau yuav tsum tau FORMABLE?
Cov hlau uas tsis zoo formability yuav ua nkig yog tias ua haujlwm ntau dhau thiab ua haujlwm qis dua. Feem ntau, martensitic steels tsis pom zoo. Tsis tas li ntawd, steel nrog tsawg formability yuav tsis tuav nws cov duab thaum complex los yog intricate forming yuav tsum tau.
Thaum xaiv cov qib steel, koj yuav xav xav txog daim ntawv uas koj xav tau xa. Txawm hais tias koj xav tau pas nrig, slabs, tuav lossis ntawv yuav txwv koj cov kev xaiv. Piv txwv li, ferritic steels feem ntau muag hauv cov ntawv txheeb, martensitic steels feem ntau muag hauv cov tuav lossis slabs, thiab cov hlau austentic muaj nyob rau hauv ntau hom ntawv. Lwm cov qib steel muaj nyob rau hauv ntau hom xws li 304, 316, 430, 2205, thiab 3CR12.
3. YUAV UA LI CAS YUAV TSUM TAU MACHINING?
Machining feem ntau tsis yog ib qho teeb meem. Txawm li cas los xij, kev ua haujlwm nyuaj tuaj yeem tsim cov txiaj ntsig uas tsis xav tau. Qhov sib ntxiv ntawm leej faj tuaj yeem txhim kho kev ua haujlwm tab sis txo cov formability, weldability thiab corrosion kuj.
Qhov no ua rau nrhiav kev sib npaug ntawm machinability thiab corrosion kuj yog ib qho tseem ceeb rau kev txiav txim siab rau feem ntau cov txheej txheem stainless hlau fabrication. Nyob ntawm koj qhov kev xav tau, qib 303, 416, 430, thiab 3CR12 muab qhov sib npaug zoo los ntawm kev xaiv nqaim ntxiv.
4. Kuv puas xav tau welding kuv STAINLESS STEEL?
Vuam stainless hlau tuaj yeem ua rau muaj teeb meem-xws li kub tawg, kev ntxhov siab corrosion tawg, thiab intergranular corrosion-nyob ntawm qib ntawm cov hlau siv. Yog tias koj npaj yuav vuam koj cov hlau tsis muaj steel, austenitic alloys yog qhov zoo tagnrho.
Cov qib carbon qis tuaj yeem pab ntxiv nrog weldability thaum cov khoom siv ntxiv, xws li niobium, tuaj yeem ruaj khov alloys kom tsis txhob muaj kev txhawj xeeb txog kev xeb. Cov qib nrov ntawm stainless hlau rau vuam muaj xws li 304L, 316, 347, 430, 439 thiab 3CR12.
5. Puas xav tau kev kho cua sov?
Yog tias koj daim ntawv thov xav tau kev kho cua sov, koj yuav tsum xav txog seb cov qib sib txawv ntawm cov hlau teb li cas. Cov yam ntxwv kawg ntawm qee cov hlau yog qhov sib txawv ua ntej thiab tom qab kev kho cua sov.
Feem ntau, martensitic thiab nag lossis daus hardening steels, xws li 440C lossis 17-4 PH, muab qhov ua tau zoo tshaj plaws thaum kho cua sov. Ntau cov austenitic thiab ferritic stainless hlau yog non-hardenable thaum tshav kub kho thiab yog li tsis yog qhov zoo tshaj plaws xaiv.
6. Lub zog ntawm cov hlau twg yog qhov zoo rau kuv daim ntawv thov?
Lub zog steel yog qhov tseem ceeb uas yuav tsum tau xav txog kom muaj kev nyab xeeb siab tshaj plaws. Txawm li cas los xij, overcompensating tuaj yeem ua rau tus nqi tsis xav tau, qhov hnyav, thiab lwm yam khoom siv khib nyiab. Cov yam ntxwv muaj zog yog xoob los ntawm tsev neeg ntawm cov hlau nrog kev hloov pauv ntxiv muaj nyob rau hauv qib sib txawv.
7. Tus nqi them ua ntej thiab lub neej tus nqi ntawm cov hlau no yog dab tsi hauv kuv qhov xwm txheej?
Tag nrho cov kev txiav txim siab yav dhau los pub rau cov lus nug tseem ceeb tshaj plaws hauv kev xaiv qib stainless hlau-tus nqi lub neej. Sib piv cov qib stainless hlau rau koj qhov chaw ib puag ncig, kev siv thiab cov kev xav tau, koj tuaj yeem ua kom muaj kev ua haujlwm ntev thiab muaj txiaj ntsig tshwj xeeb.
Ua tib zoo txheeb xyuas seb cov hlau yuav ua li cas nyob rau lub sijhawm siv thiab cov nqi dab tsi yuav cuam tshuam rau kev saib xyuas lossis hloov ua ntej txiav txim siab. Kev txwv cov nqi ua ntej yuav ua rau muaj kev siv nyiaj ntau dua hauv lub neej ntawm koj qhov project, khoom, qauv, lossis lwm yam kev thov.
Nrog rau tus lej ntawm cov qib stainless hlau thiab cov ntaub ntawv muaj, muaj ib tus kws tshaj lij los pab cov kev xaiv tseem ceeb thiab muaj peev xwm pitfalls yog ib txoj hauv kev zoo los xyuas kom meej tias koj tau txais txiaj ntsig zoo rau kev nqis peev stainless hlau.
