Duplex Duplex Stainless Steel

Super duplex birta aan daxalka lahayn waxa ay kaga duwan tahay darajooyinka laba-laabka caadiga ah iyada oo ay si weyn u wanaajisay sifooyinkeeda u adkaysiga daxalka.Waa walxo aad u alloyed oo leh xaddi sare oo ah walxo ka-hortagga daxalka sida chromium (Cr) iyo molybdenum (Mo).Heerka aasaasiga ah ee super-duplex-ka birta aan lahayn, S32750, wuxuu ka kooban yahay 28.0% chromium, 3.5% molybdenum, iyo 8.0% nikkel (Ni).Qaybahani waxay siiya iska caabin aan caadi ahayn oo ay ku jiraan walxaha daxalka ah, oo ay ku jiraan asiidhyada, chlorides, iyo xalalka caustic.

Guud ahaan, birta-super duplex-ka aan-suuxinta lahayn waxay ku dhismaan faa'iidooyinka la aasaasay ee darajooyinka laba-laabka ah ee leh xasilloonida kiimikada ee la xoojiyey.Tani waxay ka dhigaysaa heer ku habboon samaynta qaybaha muhiimka ah ee qaybta batroolka, sida kuwa kulaylka beddela, kuleyliyaha, iyo qalabka weelka cadaadiska.

Kala-soocidda Duplex Stainless Steel

Nooca kowaad waa nooca daawaha hooseeya, oo leh darajada wakiilka UNS S32304 (23Cr-4Ni-0.1N).Birtu kuma jirto molybdenum, qiimaha PRENna waa 24-25.Waxaa loo isticmaali karaa beddelka AISI304 ama 316 ee iska caabbinta daxalka.

l Nooca labaad waxaa iska leh nooca daawaha dhexdhexaadka ah, astaanta wakiilka waa UNS S31803 (22Cr-5Ni-3Mo-0.15N), qiimaha PREN waa 32-33, caabbinta daxalka waxay u dhaxaysaa AISI 316L iyo 6% Mo+N austenitic Bir daxal laheyn.

l Nooca seddexaad waa nooca daawaha sare, kaas oo guud ahaan ka kooban 25% Cr, molybdenum iyo nitrogen, iyo qaar ka mid ah sidoo kale waxaa ku jira copper iyo tungsten.Heerka caadiga ah ee UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), qiimaha PREN waa 38-39, caabbinta daxalka ee birta noocaan ah ayaa ka sareysa tan 22% Cr duplex birta aan lahayn.

Nooca afraad waa bir-super duplex ahama, kaas oo ka kooban molybdenum sare iyo nitrogen.Darajada caadiga ah waa UNS S32750 (25Cr-7Ni-3.7Mo-0.3N), qaarna sidoo kale waxaa ku jira tungsten iyo copper.Qiimaha PREN wuxuu ka weyn yahay 40, kaas oo lagu dabaqi karo xaalado dhexdhexaad ah oo adag.Waxay leedahay iska caabin daxalka wanaagsan iyo sifooyin dhammaystiran oo farsamo, kuwaas oo la barbar dhigi kara birta aan suubban ee super austenitic.

Faa'iidooyinka Duplex Stainless Steel

Sida kor lagu sheegay, Duplex caadi ahaan wuu ka fiican yahay noocyada birta gaarka ah ee laga helo qaab-dhismeedkeeda yar yar.Si fiican ayaa loo yidhi, isku darka sifooyinka wanaagsan ee ka imanaya walxaha austenite iyo ferrite waxay bixiyaan xal guud oo wanaagsan oo loogu talagalay tiro badan oo ah xaalado wax soo saar oo kala duwan.

l Waxyaabaha ka-hortagga daxalka - Saamaynta molybdenum, chromium, iyo nitrogen ee iska caabbinta daxalka ee Alloys Duplex waa mid aad u weyn.Dhowr alwaaxyo Duplex ah ayaa la mid noqon kara oo dhaafi kara waxqabadka lidka ku ah daxalka ee buundooyinka austenitic ee caanka ah oo ay ku jiraan 304 iyo 316. Waxay si gaar ah waxtar ugu leeyihiin dillaaca iyo daxalka.

Dillaaca daxalka cadaadiska - SSC waxay ku timaaddaa dhawr arrimood oo hawada ku jira - heerkulka iyo qoyaanka ayaa ah kuwa ugu cadcad.Cadaadiska adkaanta ayaa kaliya ku sii kordhinaya dhibaatada.Darajooyinka austenitic ee caadiga ah aad bay ugu nugul yihiin dillaaca daxalka - Duplex birta aan lahayn birta maaha.

l Adag - Duplex waa ka adag yahay biraha ferritic-ka ah - xitaa heerkulka hoose iyada oo aan dhab ahaantii u dhigmin waxqabadka heerarka austenitic ee dhinacan.

l Xoogga - Alloys Duplex waxay noqon karaan ilaa 2 jeer ka xoog badan labada qaab-dhismeedka austenitic iyo ferritic.Awood sare waxay ka dhigan tahay in birta ay sii ahaanayso mid adag xitaa iyadoo dhumucdiisu yar tahay taas oo si gaar ah muhiim ugu ah dhimista heerarka miisaanka.
