Cov khoom siv: Duplex Steel Astm A789 S31803, S32205, S32750, S32760

ASTM A479 DUPLEX STEEN Unasers unreakers muaj cov hlau vuam, ntshav arc vuam, submerged arc vuam thiab roj tungsten arc vuam. ASME SA 479 DUPLEX STEEN UNSER S31803 Square Washer yog ib qho Ferritic, Ausenitic 22% Molybdenum thiab 5-6% Nickel Alloy Steel.

Siab chromium, molybdenum thiab nitrogen cov ntsiab lus cuam tshuam nrog pitting tsis zoo rau cov medtenatent thiab corrosive corrosive conduction, thiab tseem ceeb pitting txias rau tag nrho cov xov xwm, thiab tseem ceeb pitting txias rau saum 50¡Ãc.

Technically, microstructure ntawm ib tus txiv neej 2205 raj yog kwv yees li 50% ferrite thiab 50% austenite. Raws li qhov tshwm sim, cov khoom tau los ntawm ob pawg ua rau cov yeeb nkab nitrogen-enhance yeeb nkab zoo xws li kev ua khoom noj thiab kev hloov pauv zaub mov thiab hluav taws xob nrawm nrawm.

Raws li muaj ntau dua tensile thiab tawm lub zog tseem muab cov ductility zoo thiab tiv taus kom muaj kev ntxhov siab corrosion.

Nyob rau hauv anealed mob, s31803 muaj kwv yees li 40-50% ferrite. S31803 feem ntau raug xa mus ua cov qib haujlwm ua haujlwm thiab yog cov dav dav siv dav dav hauv chav dej duplex pipes. Kev siv S31803 stainless hlau yeeb nkab yuav tsum tau txwv rau qhov kub thiab txias hauv qab 600¡Ãf.

A789 unc unic s31803 thiab unspes ob qib ntawm ob chav stainless hlau uas tau siv dav hauv ntau cov ntawv thov. Cov txiv neej duplex s31803 Seamless kav yog paub rau lawv cov txiv neej ua hauj lwm zoo, muaj lub zog siab, thiab weldability thiab zoo weldability. A789 yog ib qho tshwj xeeb uas tau them seamless thiab welded tub ua los ntawm duplex steel stainless hlau.
Piv nrog ferritic stainless hlau thiab Austenitic Stainless hlau, Duplex cov yeeb nkab muaj kev ua haujlwm vuam. Nws tsis yog tus dej kub uas cuam tshuam rau thaj tsam ntawm cov hlau ferritic, vim yog cov roj av uas tsis tshua muaj ntau, nws yog qhov rhiab ntau rau vuam kub tawg.
Kev paub qhov tshwm sim ib qho xwm txheej uas hu ua passivation. Los ntawm kev ntxiv cov ntsiab lus no, cov roj stainless hlau cov chaw tsim khoom hauv Is Nrias teb nce ntau yam ntawm cov qib ntawm cov hlau tsis xeb. Chromium, Molybdenum, nitrogen, thiab npib tsib yog qhov tseem ceeb tshaj plaws ntawm cov neeg kho tshuab, lub cev thiab xeb cov hlau ntawm ob lub stuplex stainless hlau. Duplex stainless hlau flanges yog qhov uas tau siv dav hauv cov roj pov thiab roj kev lag luam uas lawv tau txais cov xov xwm corrosive. Nyob rau hauv cov roj thiab roj kev lag luam, qhov kev sib kis tau, qhov kev sib kis tau tshaj tawm thoob plaws raws caij tsheb ciav hlau nrawm thiab cov khoom siv ntawm no yuav dhau los ua neeg nyob hauv no.

Lawv kuj muaj kev tiv thaiv zoo heev rau corrosion cracking thiab cov corrosion hauv zos xws li pitting, intergranular thiab crevice. Tsis zoo li lwm cov qauv Austenitic cov hlau, uns unicial uncials, steel muaj cov khoom sib nqus zoo heev.

Duplex 2205 Fasteners muaj kev siab tawv thiab hardness thaum tseem muaj qib siab ntawm lub zog siab tensile muaj zog, txhua yam ntawm cov chromium tam sim no hauv lawv. Txawm li cas los xij, nws tuaj yeem xaus lus tias dual theem steel steel fasteners yog undeniable; Tsis yog deformed tsis yog puas. Qhov no tsis tshua muaj tshwm sim. 2205 Duplex fasteners haus cov txheej txheem heev ua los ntawm ferritic thiab Austenitic steels uas tau pom zoo ib feem ntawm cov neeg kho tshuab kom zoo nkauj.

Cov khoom siv duplex muaj bot cov Austenitic thiab Ferrite qauv hauv cov metallurgy ntawm cov khoom. Cov khoom no nqa cov khoom siv zoo tshaj plaws ntawm ob hom ferritic thiab ustenitic hom steel. Cov kav dej yuav yog kub dov lossis txias txav. Cov kub dov tau cov muaj zog dua thiab cov kev tawm dag zog txias yog seamless thiab raug nyob hauv qhov ntev. Lub yeeb nkab doom nti yog siv hauv cov ntawv thov nrog cov kev xav tau siab.

Cov qauv S32750 cov qauv ntawm cov yeeb nkab fittings muaj li 25% chromium, 4% molybdenum, thiab 7% npib tsib xee. Lub unr unic s32750 cov yeeb nkab fittings muaj 50-50 microstructure ntawm Ferritic thiab Austenitic Steel qhab nia nrog kev txhim kho lub zog.

Raws li tus thawj coj thoob ntiaj teb hauv kev xa khoom thiab faib cov hlau 2205 round steel 2205 round steel 2205 round steel 220, tshuaj ntsuab thiab cov ntawv siv tshuaj tua hluav taws thiab ntau lwm cov ntawv thov.

Cov txiaj ntsig lub zog ntawm 2205 yog kwv yees li ob zaug uas ntawm Austenitic Stainless hlau. Qhov no tso cai cov tsim qauv los txo qhov hnyav thiab ua rau tag nrho cov nqi sib tw tau sib tw rau 316L lossis 317L.

Duplex 2205 flanges ua ke cov kev ua tau zoo ntawm kev ntxhov siab corrosion tsis kam thiab lub zog siab ua los ntawm kev ua ib qho kev ua kom muaj txiaj ntsig ntawm cov roj ntsha ua tau zoo.

Duplex stainless hlau muaj microstructure uas yog 50% Ferritic thiab 50% Austenic. Cov muaj pes tsawg no muab lawv lub zog zoo dua li cov hlau ferritic lossis austenitic steels. Cov ntsiab lus ntxiv txog cov ntsiab lus no tau muab hauv qab no (saib ASTM A790 kav).

A789 unc unic s31803 thiab unspes ob qib ntawm ob chav stainless hlau uas tau siv dav hauv ntau cov ntawv thov. Cov txiv neej duplex s31803 Seamless kav yog paub rau lawv cov txiv neej ua hauj lwm zoo, muaj lub zog siab, thiab weldability thiab zoo weldability. A789 yog ib qho tshwj xeeb uas tau them seamless thiab welded tub ua los ntawm duplex steel stainless hlau.
Piv nrog ferritic stainless hlau thiab Austenitic Stainless hlau, Duplex cov yeeb nkab muaj kev ua haujlwm vuam. Nws tsis yog tus dej kub uas cuam tshuam rau thaj tsam ntawm cov hlau ferritic, vim yog cov roj av uas tsis tshua muaj ntau, nws yog qhov rhiab ntau rau vuam kub tawg.
Kev paub qhov tshwm sim ib qho xwm txheej uas hu ua passivation. Los ntawm kev ntxiv cov ntsiab lus no, cov roj stainless hlau cov chaw tsim khoom hauv Is Nrias teb nce ntau yam ntawm cov qib ntawm cov hlau tsis xeb. Chromium, Molybdenum, nitrogen, thiab npib tsib yog qhov tseem ceeb tshaj plaws ntawm cov neeg kho tshuab, lub cev thiab xeb cov hlau ntawm ob lub stuplex stainless hlau. Duplex stainless hlau flanges yog qhov uas tau siv dav hauv cov roj pov thiab roj kev lag luam uas lawv tau txais cov xov xwm corrosive. Nyob rau hauv cov roj thiab roj kev lag luam, qhov kev sib kis tau, qhov kev sib kis tau tshaj tawm thoob plaws raws caij tsheb ciav hlau nrawm thiab cov khoom siv ntawm no yuav dhau los ua neeg nyob hauv no.

Lub duplex microstructure tso cai rau qib siab DUPLAS UNLENTIVE thiab siab dua rau kev ua haujlwm kub thiab txias rau 300¡ling.

Sa 815 s31803 Weld fittings muaj cov tshuaj lom neeg tshwj xeeb nrog rau lub zog siab dua thiab zoo ua rau xeb. Yog li cov qib kawm no yog siv rau kev tsim khoom lag luam. Sa 815 S31803 ntev \ / Luv Radius Lauj Zaub Zoo Tshaj Tawm rau Pitting, Crevice Corrosion thiab muaj kev muaj txiaj ntsig zoo. Lawv zoo tag nrho yog tias ib tug tab tom nrhiav rau cov yeeb nkab ruaj khov nrog cov qauv zoo. ASME B16.9 WPS Tsis Txaus S31803 Lub lauj tshib tseem ua rau pom kev ua kom zoo rau cov acetic thiab cov chaw muaj dej hiav txwv.

Duplex 2205 yog nitrogen txhim kho duplex stainless hlau tsim los daws cov teeb meem corrosion engless cov.

Duplex alloys muaj qee qhov kev ntxhov siab Ferritic kev ua txhaum kev tawg ntawm ib qho kev ua kom zoo tshaj plaws alloys uas tau tus nqi ntau dua li cov nickel ntau dua li alloys.
