2205 Tšepe e Hloekileng
Melemo ea Bohlokoa ea Duplex 2205
Karolelano e Ikhethileng ea Matla ho isa ho Boima: Kereiti ea 2205 e fana ka matla a tlhahiso hoo e ka bang habeli a litšepe tse tloaelehileng tsa austenitic. Sena se lumella mehaho (lijana, litanka, liphaephe, joalo-joalo) hore li hahoe ka 30-50% ka mokhoa o mosesaane, ho fokotsa haholo boima le litšenyehelo tsa thepa ha li ntse li boloka litekanyetso tse tšoanang tsa khatello kapa matla a mojaro.
E Hlollang ka ho Fetisisa Corrosion Resistance: Boleng bo phahameng ba chromium, molybdenum, le naetrojene bo fana ka 2205 tšepe e sa hloekang ho feta 316L/317L. E hanela ho bola le ho bola libakeng tse nang le chloride ka katleho ho feta limaraka tse 300. Mecheng ea litaba e mabifi kapa metsing a leoatle, duplex 2205 hangata e feta li-austenitics tse tloaelehileng; Super duplex alloys e ka nka sebaka sa li-alloys tsa nickel tse turang haholo maemong a thata ka ho fetesisa.
Superior Stress Corrosion Cracking Resistance:The duplex microstructure e fana ka khanyetso e ikhethang ho chloride stress corrosion cracking (SCC). Le limaraka tse tlase tse tlase li feta 304/316 ntle le litšila litekong tsa SCC. Sena se etsa hore 2205 e be e loketseng bakeng sa tikoloho e metsi, ea letsoai, kapa ea brackish (lisebelisoa tsa metsing, ho ntša letsoai, ho pholile ha metsi a leoatle, joalo-joalo) moo litšepe tsa austenitic li ka senyehang tlas'a khatello ea maikutlo.
Mathata a Phahameng le Matla a Mokhathala: Duplex 2205 e boloka ho tiea ho hoholo (esita le lithempereichara tse ka tlase ho zero) 'me e hanela ho hola ha crack tlas'a cyclic loading e betere ho feta li-alloys tse lekanang tsa austenitic. E monya matla a mangata ka tlas'a tšusumetso kapa ho sisinyeha, ho etsa hore e be matla haholoanyane tlas'a meroalo e matla kapa ea tšohanyetso. Boima ba eona bo phahameng ha bo bapisoa le 304/316 ea annealed bo boetse bo fana ka khanyetso e ntlafetseng ea ho apara maemong a ho senya.
Katoloso e Tlase ea Thermal le Tšebelisano ea Carbon-Steel:Sehlopha sa 2205 se na le coefficient e batlang e le tlase ea katoloso ea mocheso (haufi le ea carbon steel). Sena se molemo ha ho chesetsoa kapa ho roala laminating ho tšepe ea carbon, kaha litekanyetso tse tšoanang tsa ho atolosa li fokotsa khatello ea kelello le ho khopama. E boetse e boloka botsitso ba dimensional ho liphetoho tsa mocheso ho feta li-alloys tse 300-series.

Liindasteri tsa Lik'hemik'hale le Ts'ebetso: E loketse likepe tsa khatello, litanka tse bolokang khatello e phahameng, liphaephe, le li-exchangers tsa mocheso limela tsa lik'hemik'hale, tlhahiso ea acid, le li-petrochemical refineries. E sebetsana le li-acid tse senyang, li-alkalis, le lihlapolli moo 300-series ea stainless e ka hlolehang.
Oli, Khase le Offshore: E sebelisoa liphaepheng, risers, separators, le likarolo tsa sethala. Ho hanyetsa ha eona ho corrosion corrosion cracking ea chloride ho etsa hore e be ea bohlokoa bakeng sa lipompo tsa ente ea metsi a leoatle, lipeipi tsa metsi a letsoai, le tikoloho ea maoatleng a tlhahlobo le tlhahiso ea kantle ho naha.
Phekolo ea Metsi le ho Ntša letsoai: E hiriloe lits'ebetsong tse futhumatsang metsi a leoatle, litsing tsa ho tlosa letsoai le ho hloekisa metsi a litšila. Ho hanyetsa ha likoti tsa Duplex 2205 ho netefatsa bophelo bo bolelele ba ts'ebeletso ha u kopana le brines kapa metsi a hloekisitsoeng.
Indasteri ea Pulp & Paper: E sebelisoa ka har'a tšilo ea lijo, litora tsa bleaching le litanka tsa polokelo ea lik'hemik'hale. E mamella mocheso o phahameng le lik'hemik'hale tse mabifi (joaloka chlorine dioxide le joala ba caustic) tse kopanang le ts'ebetso ea ho phunya le ho soeufatsa.
Phetoho ea Lijo, Seno le Meriana: E loketse litanka, lipeipi, le lisebelisoa tsa ho lokisa lijo, ho ritela, lebese le limela tsa meriana. E fana ka matla le ho hanyetsa ho bola tlas'a tlhoekiso e matla ea bohloeki le litekanyetso tsa bohloeki.
Mechini ea Indasteri le Likarolo tsa Marine: E sebelisoa likarolong tsa pompo le li-valve, li-impellers, shafts le likarolo tsa meralo tse hlokang matla a phahameng le ho hanyetsa kutu. E boetse e sebelisoa kahong ea likepe, meahong e kantle ho naha, le litsing tsa lipalangoang tse pepesehileng maemong a thata.
Lisebelisoa tse ling tsa Boenjiniere: Kae kapa kae moo motsoako oa matla a phahameng, ho tiea, le ho hanyetsa ho bola ho hlokahalang. Mehlala e kenyelletsa li-fasteners, li-flange, li-tubing tse futhumatsang mocheso, le likarolo tsa meralo ho fehlang motlakase, merafong le tlhahisong e akaretsang.
