1.Txoj kev tsis muaj hlau
Stainless hlau corrosion
Raws li peb twb tau hais, stainless hlau yog paub rau nws corrosion-resistant cov khoom; Nws yog dab tsi cais nws los ntawm cov hlau tsis tu ncua. Lub chromium hauv lub alloy muab cov hlau ib txheej oxide, uas yog dab tsi muab nws nws cov cuab yeej-resistant. Oxide txheej yog kev kho tus kheej rau nws tus kheej, thiab txawm tias cov nplaim dej puas, nws tseem yuav tiv taus kev xeb.
Nyob rau hauv kev sib piv, cov hlau hlau muaj kev tiv thaiv los ntawm cov txheej ci zoo li galvanizing. Hmoov tsis zoo, kev puas tsuaj rau saum npoo yuav nthuav tawm cov hlau thiab tawm rau nws qhib rau corrosion, yog li nws tuaj yeem ua teeb meem nrog nws lub neej muaj txiaj ntsig.
Cov qhab nia sib txawv ntawm cov hlau muaj sib txawv tsis kam, thiab chloride ua kom du hauv cov qib hauv qee qib. Qib nrog npib tsib xee, chromium thiab molybdenum yog qhov feem ntau tiv taus corrosion.
Stainless Hlau Magnetism
Magnetism yog qhov kev nyiam ntawm cov hlau rau cov hlau nplaum. Austenitic qib tsis feem ntau tsis sib nqus, Txawm hais tias Magnetism tuaj yeem ua tiav nrog kev ua haujlwm txias. Cov qhab nia nrog cov ntsiab lus muaj npe siab kuj tseem yuav tsis yog kev sib nqus, thiab cov hlau ferritic yog sib nqus.
Stainless hlau tensile zog
Thaum muab piv nrog cov hlau me me, hlau stainless muaj ntau lub zog, thiab cov yas stuplex muaj qhov zoo tshaj plaws lub zog tshaj li Austenitic steel.
Txawm li cas los xij, cov hlau siab tshaj plaws tau pom hauv Martensitic Steel thiab tuaj yeem muaj zog ntau dua li ntawm cov hlau saum toj no.
Stainless hlau Cryogenic Kuj
Ntawm sub-xoom qhov kub thiab kev ua kom nruj thiab ductility ntawm Austenitic Stainless hlau yog nce, werritic thiab martititic stainless hlau yuav tsum tsis txhob siv nyob rau ntawm cov ntsuas kub no.
2.types ntawm stainless hlau
Stainless hlau los ntawm plaub lub ntsiab: Austenitic, Ferritic, martensitic, thiab duplex. Txhua hom muaj cov khoom tshwj xeeb thiab yog siv rau cov ntawv thov sib txawv, raws li nws muaj pes tsawg leeg thiab microstructure.
Austenitic Stainless Hlau
Feem ntau cov hom paub rau nws zoo heev corrosion tsis kam, ductility, thiab weldability.
Kev siv ntau yam:Cov cuab yeej siv khoom noj, khoom siv kho mob, thiab cov nroj tsuag siv tshuaj lom neeg.
Kev ua tau zoo:Txhim kho cov ntsiab lus npib tsib xee cov ntsiab lus tiv thaiv kev tawm tsam pitting hauv qhov chaw hnyav.
Ferritic Stainless Hlau
Nqis thiab sib nqus, nrog zoo corrosion tsis kam rau sab hauv tsev lossis cov ntawv thov dav dav.
Kev siv ntau yam:Lub zog tsheb, cov khoom siv chav ua noj, thiab dej huv si.
Nqi Them Nqi:Muaj me ntsis tsis muaj menyuam yaus, ua rau nws pheej yig dua li kev siv roj av.
Martensitic Stainless Hlau
Muaj zog thiab hnav-resistant, ua rau nws zoo tagnrho rau cov ntawv thov kev ntxhov siab kev ntxhov siab.
Kev siv ntau yam:Kev phais cov twj paj nruas, cutlery, thiab aerospace Cheebtsam.
Lub zog siab:Harder thiab nruj tshaj li Austenitic thiab Ferritic qib tab sis nrog qis corrosion tsis kam.
Duplex Stainless Hlau
A 50\/50 sib xyaw ntawm cov tshuaj austenitic thiab ferritic cov khoom, muab lub zog siab thiab zoo dua rau kev xeb.
Kev siv ntau yam:Roj thiab roj pipelines, cov hlab ntsha siab, thiab ua tub rog.
Cov ntawv thov siv hnyav:Qhov zoo tshaj plaws rau ib puag ncig muaj kev ntxhov siab corrosion cracking thiab chloride kis.
