304 Hlau Hlau yog av rau Coils, daim ntawv, cov khoom siv, khoom siv (piv txwv li cov khoom siv hauv qab, kev phais cov khoom siv thiab cov khoom siv tsim hauv tsev.

Ib lub super duplex stainless hlau yog txhais ua lub hlwv yas nrog pitting corrosion (pre)>% (% mo + + 1 x 100 n. Usually super duplex steels have a chromium content of 25% or more, some common examples are S32760 (Zeron 100), S32750 (2507) and S32550 (Ferralium), but not all Ferralium grades are super duplex steels.

Cov hlau duless stainless muaj ib tug sib xyaw microstrite thiab ferrite, thiab lub hom phiaj feem ntau yog tsim muaj alloys muaj ntau yam no yuav yog 40 \ / 60. Duplex stainless hlau yog kwv yees li ob zaug uas muaj zog raws li cov hlau tsis muaj zog, tshwj xeeb yog pitting, kev ntxhov siab corrosion thiab kev ntxhov siab corrosion tawg.

Nyob rau hauv 304 stainless hlau phaj, ferritic stainless hlau feem ntau muaj cov khoom siv roj hluav taws xob zoo dua li cov ntsiab lus chromium thiab npib tsib xee, xeb tawm tsam yog txo. Lawv kuj yog pheej yig dua.

Thaum cov ntsiab lus chromium ntawm alloy yog qis dua tsawg kawg yog 12%, piv txwv li hauv Aerospace kev lag luam, lo lus "corrosion resistant steel" yog siv. Stainless tus hlau los hauv cov qib sib txawv thiab cov npoo ua tiav, nyob ntawm seb nws siv qhov twg.

Qeb 304 muaj cov cwj pwm vuam zoo thiab feem ntau tsis tas yuav tsum tau tom qab Weld annaling los rov ua tau zoo. 304 ss muaj cov tshuaj tiv thaiv corrosion zoo tshaj plaws nyob rau ntau yam sib txawv.

Stainless hlau muaj zog dua mus rau oxidation (xeb) thiab corrosion nyob rau hauv ntau ib puag ncig ntuj thiab txiv neej ib puag ncig; Txawm li cas los xij, nws yog ib qho tseem ceeb kom xaiv qhov tseeb hom stainless hlau rau siv. Muaj ntau dua 150 qib ntawm stainless hlau, ntawm uas 15 yog qhov siv tshaj plaws.

HT yog ib qho ntawm sab saum toj feem ntau cov chaw tsim khoom lag luam ntawm? Ss 316ti daim hlau, uas muaj sib npaug corrosion tsis kam rau qhov tsis muaj zog raws li cov pa roj carbon ntau 316L. ASTM A240 LWSESS STEEL 316TI daim hlau yog tsis yog kev ua tsis tau nyob hauv cov kev mob anealed.

Zej zog hatening martitic stainless hlau tau sib piv corrosion tau sib piv rau cov qib me me, tab sis tuaj yeem ua ntej lub zog siab dua li lwm cov qhab nia Martensitic. Feem ntau 17-li 17-4pha siv txog 17% chromium thiab 4% npib tsib xee. Lub Lockheed-Martin Sib Koom Hlau Fighter yog thawj lub dav hlau siv nag lossis daus-ua rau cov tawv ntoo tsis zoo-stainless hlau ntoo ua haujlwm 465 hauv nws cov fuselage.

Lub 1.4539 lub phaj yog tus qauv uas tswj hwm cov tuab ntawm cov ntawv txheeb thiab daim hlau. Muaj ntau cov lus qhia sib txawv los npog cov ntawv txheeb thiab cov phaj ib yam nkaus.

Qeb 304 Stainless hlau yog feem ntau suav hais tias yog feem ntau cov untenenitic steel hlau. Nws muaj cov ntsiab lus npib tsib xee uas yog feem ntau ntawm 8 thiab 10.5 feem pua ​​los ntawm qhov hnyav thiab qhov siab ntawm cov chromium ntawm kwv yees li 18 txog 20 feem pua ​​los ntawm qhov hnyav. Lwm cov ntsiab lus qub muaj xws li manganese, silev, thiab carbon. Qhov seem ntawm cov tshuaj lom neeg muaj pes tsawg leeg yog feem ntau hlau.

Nws ua haujlwm nyob rau hauv ob qho tib si kev xyaum kub thiab txias. SS 316Ti yog zoo kawg nkaus kom siv nyob rau hauv cov mob corrosive. Nws yog kiag li ustenitic thiab muaj siab dua molybdenum cov ntsiab lus uas muab rau nws ib qho kev tiv taus siab.

A240 316ti steel phaj? Qhov kev ua tau zoo tshaj plaws yog qhov zoo dua li 15% thiab ntau dua 85%, 316 stainless hlau nrog ntau hom kev siv. 316TI Stainless hlau thiab chloride kuj muaj cov kev ua tau zoo corrosion, feem ntau nws yog siv rau hauv ib puag ncig marine.

Sa240 1.4436 lub phaj feem ntau muaj nyob hauv cov thicknesses los ntawm 0.1875 nti rau 48 ntiv tes mus txog 120 ntiv tes (121 hli txog 3048 hli). Qhov ntev ntawm 1.4401 lub phaj tuaj yeem raug kho raws cov neeg siv khoom. Koj tuaj yeem tshawb xyuas SS 316 phaj nqi ntawm HT YEJ!

Rau 304 stainless hlau phaj rov ua dua tshiab, muaj kev ua lag luam theem nrab rau kev rov ua dua tshiab rau ntau yam khoom lag luam steel. Cov khoom lag luam feem ntau yog cov coils, cov ntawv qhia thiab cov seem. Cov ntaub ntawv no yuav tau thiab muag ntawm hauv qab no cov nqi zoo tshaj plaws rau kev ua lag luam zoo nkauj thiab cov tuam txhab hlau. Cov ntaub ntawv yuav muaj khawb, pits thiab dents tab sis yog tsim tawm rau cov specifications tam sim no.

Yuav kom ua tiav cov kev tiv thaiv corrosion tsis kam, ua rau lub zog kho cua sov ua tau. Txij li thaum chromium carbides tshem tawm qhov kub tsawg dua li titanium carbides yuav tswj tau kub hnyo yuav precipitate tab sis chromium tseem nyob hauv kev daws teeb meem. Tom qab soaking nyob rau hauv lub stabilizing kub rau tsawg kawg 2 teev, hom 316ti yuav tsum txias heev los ntawm huab cua.

Cov kav hlau steel tuaj yeem ua kom tawg ntawm lub hauv paus ntawm nws daim ntawv thov. Cov Kev Siv Cov Kav Hlau Hlau yog nyob rau thaj chaw ntawm cov kav dej, kev lag luam raj, cov kab ua liaj ua teb, cov lag luam raj, siv tsheb thiab lwm yam kev lag luam.
