SUH409 Stainless hlau

SUH409 yog ferritic stainless hlau nrog cov ntsiab lus chromium tsawg (11-13%), ua kom zoo rau tus nqi-kev ua tau zoo thiab tsim tau zoo. Nws ruaj khov nrog titanium los tiv thaiv rhiab heev, ua rau nws zoo tagnrho rau kev siv lub tshuab hluav taws xob thiab kev siv hluav taws xob tsawg. Tsis zoo li cov qib austenitic, nws tsis muaj npib tsib xee, muab cov txiaj ntsig kev lag luam thaum tswj kev xeb yooj yim.

FAQ

1. Q: Vim li cas SUH409 yog siv dav hauv cov khoom siv tsheb? A: SUH409 tus nqi qis thiab titanium stabilization ua rau nws zoo meej rau cov pa tawm. Nws cov qauv ferritic tiv thaiv thermal qaug zog los ntawm kev rov ua cua sov / cua txias, ib qho teeb meem tshwm sim hauv cov tshuab pa. Nws tiv taus 600 degree, sib piv cov pa khiav haujlwm, thiab tsis txhob xeb los ntawm ya raws. Tsis zoo li npib tsib xee- muaj cov qib, nws tus nqi qis haum rau kev tsim tsheb loj. Nws formability kuj tso cai rau shaping rau hauv complex pa Cheebtsam yooj yim.

2. Q: SUH409 piv rau SUS430 li cas? A: SUH409 muaj qis dua Cr (11-13% vs 16{11}}18% hauv SUS430) tab sis zoo dua siab -temp stability. SUS430 muaj kev tiv thaiv corrosion zoo tshaj rau cov khoom siv hauv chav ua noj, thaum SUH409 ua tau zoo hauv kev siv hluav taws xob ntau / tsheb siv. SUH409 yog pheej yig dua vim qis alloy cov ntsiab lus. Ob leeg yog ferritic, tab sis SUH409's titanium stabilization txo cov teeb meem vuam, tsis zoo li SUS430 uas yuav xav tau kev kho tom qab vuam.

3. Q: SUH409 puas tuaj yeem welded? A: Yog, SUH409 yog weldable ntawm TIG / MIG txoj kev. Titanium stabilization tiv thaiv chromium carbide nag lossis daus nyob rau hauv tshav kub- cuam tshuam cheeb tsam, zam intergranular corrosion. Siv qhov sib txuam 409 muab tub lim hlau los tswj cov khoom. Tswj cov khoom siv hluav taws xob los tiv thaiv kev loj hlob ntawm cov qoob loo- cov cua kub ntau dhau los txo cov ductility. Nws yog weld ntau dua -tus phooj ywg zoo dua tsis yog{11}} qib ferritic ruaj khov, haum rau kev tsim cov pa tawm thiab cov kav dej.

4. Q: Puas yog SUH409 haum rau kev siv sab nraum zoov? A: Nws ua haujlwm rau qhov chaw sab nraum zoov me me xws li cov khoom siv ua liaj ua teb lossis cov khoom siv kho kom zoo nkauj. Nws 11-13% Cr tsim cov txheej txheem oxide yooj yim tiv thaiv xeb hauv qhuav / ntub tsis yog- mob hnyav. Zam cov chaw ntug dej hiav txwv uas muaj ntsev txau-tsawg Cr tsis tuaj yeem tiv taus pitting muaj. Rau qhov hnyav sab nraum zoov, xaiv SUS304 lossis siab dua Cr qib. Kev tu tsis tu ncua ncua nws lub neej kev pab sab nraum zoov los ntawm kev tiv thaiv cov av.

5. Q: Lub luag haujlwm ntawm titanium hauv SUH409 yog dab tsi? A: Titanium khi nrog cov pa roj carbon, tiv thaiv chromium carbide tsim ntawm cov ciam teb thaum lub sij hawm vuam / cua sov. Yog tsis muaj titanium, cov pa roj carbon reacts nrog chromium, depleting Cr ze ntawm cov ciam teb thiab ua rau intergranular corrosion. Titanium ua kom cov khoom sib xws Cr faib, tswj kev tiv thaiv corrosion. Nws kuj tseem ua kom zoo dua cov qauv nplej, txhim kho siab -temp lub zog- tseem ceeb rau kev tso pa tawm hauv qab cua sov.
