Cov Lus Qhia Txog Khoom

Cov Cim Npe Khoom

Txheej txheem cej luam ntawm Duplex Stainless Steel

Cov hlau tsis xeb super duplex txawv ntawm cov qib duplex txheem los ntawm nws cov khoom tiv taus xeb zoo dua. Nws yog cov khoom siv sib xyaw ua ke nrog cov khoom tiv thaiv xeb xws li chromium (Cr) thiab molybdenum (Mo). Cov hlau tsis xeb super duplex tseem ceeb, S32750, muaj txog li 28.0% chromium, 3.5% molybdenum, thiab 8.0% nickel (Ni). Cov khoom no ua rau muaj kev tiv taus zoo rau cov neeg ua haujlwm corrosive, suav nrog cov kua qaub, chlorides, thiab cov kua caustic.

Feem ntau, cov hlau tsis xeb super duplex yog tsim los ntawm cov txiaj ntsig ntawm cov qib duplex nrog kev ruaj khov tshuaj lom neeg zoo dua. Qhov no ua rau nws yog qib zoo tagnrho rau kev tsim cov khoom tseem ceeb hauv kev lag luam petrochemical, xws li cov khoom siv hloov pauv cua sov, boilers, thiab cov khoom siv siab.

Kev faib tawm ntawm Duplex Stainless Steel

l Hom thawj yog hom hlau tsis tshua muaj hlau, nrog rau qib sawv cev ntawm UNS S32304 (23Cr-4Ni-0.1N). Cov hlau tsis muaj molybdenum, thiab tus nqi PREN yog 24-25. Nws tuaj yeem siv hloov AISI304 lossis 316 hauv kev tiv thaiv kev ntxhov siab.

l Hom thib ob yog hom hlau nruab nrab, lub npe sawv cev yog UNS S31803 (22Cr-5Ni-3Mo-0.15N), tus nqi PREN yog 32-33, thiab nws qhov kev tiv thaiv corrosion yog ntawm AISI 316L thiab 6% Mo + N austenitic stainless hlau.

l Hom thib peb yog hom hlau sib xyaw siab, uas feem ntau muaj 25% Cr, molybdenum thiab nitrogen, thiab qee qhov kuj muaj tooj liab thiab tungsten. Qib txheem UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), tus nqi PREN yog 38-39, thiab qhov tsis kam ntawm hom hlau no siab dua li ntawm 22% Cr duplex stainless hlau.

l Hom plaub yog super duplex stainless hlau, uas muaj molybdenum thiab nitrogen ntau. Qib txheem yog UNS S32750 (25Cr-7Ni-3.7Mo-0.3N), thiab qee qhov kuj muaj tungsten thiab tooj liab. Tus nqi PREN ntau dua 40, uas tuaj yeem siv rau cov xwm txheej nruab nrab hnyav. Nws muaj kev tiv thaiv corrosion zoo thiab cov khoom siv kho tshuab, uas tuaj yeem sib piv nrog super austenitic stainless hlau.

Cov txiaj ntsig ntawm Duplex Stainless Steel

Raws li tau hais los saum toj no, Duplex feem ntau ua tau zoo dua li cov hlau ib leeg uas pom hauv nws cov qauv me me. Zoo dua hais tias, kev sib xyaw ua ke ntawm cov yam ntxwv zoo los ntawm austenite thiab ferrite cov ntsiab lus muab kev daws teeb meem zoo dua rau ntau qhov xwm txheej sib txawv.

l Cov khoom tiv thaiv xeb - Cov nyhuv ntawm molybdenum, chromium, thiab nitrogen rau kev tiv thaiv xeb ntawm Duplex alloys yog qhov loj heev. Ntau yam Duplex alloys tuaj yeem phim thiab tshaj qhov kev ua tau zoo tiv thaiv xeb ntawm cov qib austenitic nrov suav nrog 304 thiab 316. Lawv tshwj xeeb tshaj yog ua tau zoo tiv thaiv kev tawg thiab xeb pitting.

Kev tawg ntawm kev ntxhov siab ntawm xeb - SSC los ntawm ntau yam huab cua - qhov kub thiab av noo yog qhov pom tseeb tshaj plaws. Kev ntxhov siab ntawm tensile tsuas yog ntxiv rau qhov teeb meem. Cov qib austenitic ib txwm muaj kev cuam tshuam loj heev rau kev ntxhov siab ntawm xeb - Duplex stainless hlau tsis yog.

l Kev Tawm Tsam - Duplex yog qhov nyuaj dua li cov hlau ferritic - txawm tias thaum kub qis dua thaum nws tsis phim qhov kev ua tau zoo ntawm cov qib austenitic hauv qhov no.

l Lub Zog - Duplex alloys tuaj yeem muaj zog txog li 2 npaug ntau dua li ob qho tib si austenitic thiab ferritic qauv. Lub zog siab dua txhais tau tias cov hlau tseem ruaj khov txawm tias txo qhov tuab uas yog qhov tseem ceeb rau kev txo qhov hnyav.
