304 Stainless Hlau

304 Stainless Hlau Qib: 0CR18NI9 (0cr19NI9) 06cr19NI9 S30408
Tshuaj lom neeg siv tshuaj: c: ≤0.08, si: ≤1.0, X: 8.0 ~ 20,5, P: ≤0.035 N≤0.1.
Piv nrog 304L
304l yog ntau corrosion resistant thiab muaj cov roj carbon tsawg dua.
304 yog siv dav thiab muaj cov khoom lag luam zoo, kub tsis kam, tsawg kub lub zog thiab cov khoom siv kho tshuab; Nws muaj cov khoom kub zoo xws li Stamping thiab khoov, thiab tsis muaj cua sov, siv kub -1 ° C ~ 800 ° C).
Tom qab vuam lossis ntxhov siab, 304l muaj qhov ua tau zoo heev rau intergranular corrosion; Nws tuaj yeem tswj hwm cov zoo corrosion tsis muaj kev kho cua sov, thiab siv qhov ntsuas kub yog -196 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C-800 ° C.

Qhov xwm txheej yooj yim
Raws li kev tsim qauv, nws tau muab faib ua kub dov thiab muab faib ua ke, thiab ua kom muaj zog, thiab, martens, nag lossis daus. Nws yuav tsum tau withstand cov xeb ntawm ntau cov kua qaub xws li cov acid, nitric acid, etcor acid, etc. etc. Zoo li ntau qhov chaw ntawm kev tsim kho, chav ua noj tais diav chav ua noj, tab tom, tsheb, thiab khoom siv hauv tsev.
Qhov saum npoo ntawm stainless hlau phaj yog du, nrog lub siab muaj zog, muaj zog thiab kev tiv thaiv muaj zog, thiab muaj zog, cov ntsiab lus thiab lwm yam xov xwm. Nws yog ib qho hlau alloy uas tsis yooj yim rau xeb, tab sis nws yog tsis muaj xeb-dawb.
Stainless hlau daim phiaj tau muab faib ua kev faib tawm hauv kub thiab txias dua raws li txoj kev tsim khoom, nrog rau cov phaj txias ntawm 0.02-4 daim hlau thiab tuab ntawm cov 4.5-100 hli.
Txhawm rau kom ntseeg tau tias cov tshuab cov khoom siv ntawm ntau cov paib hlau ua ntej, kev kho mob tense, thiab kev kho mob daws teeb meem ua ntej xa khoom.
Lub corrosion tsis kam ntawm stainless hlau feem ntau yog nyob ntawm nws cov qauv alloy (chromium, thiab lwm yam lub luag haujlwm yog ua si los ntawm chromium. Chromium muaj cov tshuaj muaj txiaj ntsig zoo thiab tuaj yeem tsim cov duab sib kis rau ntawm cov hlau saum npoo av, tiv thaiv cov hlau los ntawm cov hlau sab nraud, thiab nce cov corrosion tsis kam ntawm cov hlau phaj. Tom qab cov zaj duab xis passive yog pov tseg, cov corrosion tsis kam.

Ceev ntawm 304 stainless hlau 7.93 g / cm3 Austenitic stainless hlau feem ntau siv tus nqi no 304 chromium cov ntsiab lus (%, 304 yog sib npaug rau kuv lub teb chaws 0cr19ni9) Stainless hlau
304 Stainless hlau yog lub universal stainless hlau cov khoom siv muaj zog tiv taus ntau dua 200 series stainless hlau cov ntaub ntawv. Nws tseem zoo dua nyob rau hauv cov kub ua hauj.
304 Stainless hlau muaj cov khoom lag luam zoo heev thiab zoo hauv kev txhim kho corrosion.
Rau oxidizing acid, qhov kev sim qhia pom tau tias: hauv nitric acid hauv qab kub nrog lub conc65%, 304 stainless hlau muaj muaj zog corrosion. Nws tseem muaj cov kev ua kom zoo rau cov kev daws teeb meem alkaline thiab feem ntau cov organic thiab inorganic acids.

Cov yam ntxwv dav dav
304 Stainless Hlau Phaj tau zoo nkauj nto thiab ntau yam kev siv tau
Zoo corrosion tsis kam, ntev dua li cov steel hlau zoo li qub
Lub zog siab, yog li nyias daim hlau yuav tsum tau siv ntau dua
Kev kub siab oxidation tsis kam thiab lub zog siab, yog li nws tuaj yeem tiv thaiv tau hluav taws kub
Kev ua taws kub ib txwm muaj, uas yog, yooj yim siv
Txij li thaum tsis muaj kev kho npoo saum npoo, nws yog qhov yooj yim thiab yooj yim tswj
Huv si thiab siab tiav
Zoo vuam kev ua tau zoo
