Txheej txheem cej luam ntawm Ob Tus Hlau Stainless

Super Duplex Stainless hlau yog txawv los ntawm cov qauv duplex qhab nia los ntawm nws qhov kev txhim kho corrosion-resistant cov khoom. Nws yog cov khoom siv tau sib xws nrog cov khoom siv nce siab ntawm cov khoom siv los tiv thaiv corrosive xws li chromium (cr) thiab molybdenum (mo). Thawj qib super duplex stainless hlau stainless hlau, muaj ntau npaum li 28.0% chromium, 3.5% molybdenum, thiab 8.0% npib tsib caug (ni). Cov cheebtsam no tau cuam tshuam nrog cov neeg sawv cev corrosive, suav nrog cov kua qaub, chlorides, thiab cov kev daws teeb meem.

Feem ntau, super duplex stainless hlau tsim thaum tsim cov txiaj ntsig tau tsim ntawm cov qhab nia ntawm cov qib hloov hluav taws xob. Qhov no ua rau nws yog ib qho zoo tshaj plaws rau cov khoom siv hluav taws xob hauv cov petrochemical sector, xws li tshav kub ua pa, boilers, thiab siab txog cov khoom siv.

Kev faib tawm ntawm cov hlau stainless

L Cov hom thawj yog hom qis qis, nrog cov neeg sawv cev ntawm cov neeg sawv cev 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 ntxhov siab corrosion.

l Cov hom thib ob belongs rau hom nruab nrab, tus sawv cev hom yog 32-33, thiab nws cov nqi corrosion yog 326L thiab 6% mo + n ustenitic Stainless hlau.

L Qhov thib peb yog hom siab ntau, uas feem ntau muaj 25% cr, molybdenum thiab nitrogen, thiab qee leej kuj muaj tooj liab thiab tungsten. Tus qauv qib unss32550 (25CR-6MO-2CU-2CU-2CU-2CU-2CU-0.2-39, thiab kev xeb tsis kam ntawm cov hlau no siab dua li ntawm cov hlau tsis muaj 22%.

L Cov hom plaub yog super duplex stainless hlau stainless, uas muaj siab siab molybdenum thiab nitrogen. Tus qauv qib tsis yog S32750 (25cr-7Ni-3.7mo-3.3n), thiab qee tus kuj muaj tungsten thiab tooj liab. Tus nqi pren yog ntau dua 40, uas tuaj yeem siv rau cov xwm txheej hnyav. Nws muaj cov zoo corrosion tsis kam thiab tshuab ua haujlwm nkag tau zoo, uas tuaj yeem sib piv nrog cov hlau tsis muaj roj stainless.

Cov txiaj ntsig ntawm Chav Hlau Stainless

Raws li tau teev saum toj no, Duplex yog ib txwm ua tau zoo dua li cov qauv steel pom hauv nws cov microstructure. Zoo dua hais tias, kev sib xyaw ua ke ntawm cov yam ntxwv zoo los ntawm Austenite thiab Ferrite lub ntsiab lus muab ib qho kev daws teeb meem zoo dua rau cov neeg sib txawv ntau yam.

Kuv tiv thaiv corrosive - cov nyhuv ntawm Molybdenum, chromium, thiab nitrogen on corrosion tsis kam ntawm dupposion yog loj heev. Ob peb lub alloys tuaj yeem sib phim thiab tshaj qhov kev ua tau zoo ntawm cov qib tsis txaus ntseeg suav nrog 304 thiab 316. Lawv tau tshwj xeeb tshaj yog tiv thaiv kev ua pob thiab pitting corrosion.

l Kev ntxhov siab corrosion tawg - SSC los ntawm ob peb lub tshuab hluav taws xob - kub thiab av noo ua cov ntawv pov thawj tshaj plaws. Tensile kev ntxhov siab tsuas yog ntxiv rau qhov teeb meem. Cov qib tsis txaus ntseeg tau muaj kev ntxhov siab heev rau kev tawg pleb - Duplex Stainless hlau tsis yog.

L Toughness - Duplex yog nyuaj dua li ferritic steels - txawm tias ntawm qis dua kub thaum nws tsis tau phim cov kev ua tau zoo ntawm kev ua haujlwm ntawm no.

Kuv muaj zog - alloys tuaj yeem muaj txog li 2 lub sij hawm muaj zog dua li ob qho tib si ustenitic thiab ferritic qauv. Lub zog siab dua txhais tau tias cov hlau nyob ruaj khov txawm tias muaj cov tuab tuab uas muaj qhov tshwj xeeb tshaj yog rau qib phaus.
