S32750 Stainless Steel Seamless Tubing

Tlhaloso e Khutšoanyane:

Alloy 2507, e nang le nomoro ea UNS S32750, ke motsoako oa mekhahlelo e 'meli o thehiloeng ho sisteme ea tšepe-chromium-nickel e nang le sebopeho se tsoakiloeng sa boholo bo lekanang ba austenite le ferrite. Ka lebaka la duplex phase balance, Alloy 2507 e bonts'a khanyetso e ntle ho kutu e akaretsang joalo ka litšepe tse se nang mochini tsa austenitic tse nang le likarolo tse tšoanang tsa alloying. Ntle le moo, e na le matla a phahameng a ho tiea le ho kotula hammoho le khanyetso e ntle ea chloride SCC ho feta balekane ba eona ba austenitic ha e ntse e boloka matla a matla ho feta balekane ba ferritic.

Super Duplex e sa hloekang joalo ka S32750, ke sebopeho se kopaneng sa austenite le ferrite (50/50) se ntlafalitseng matla ho feta limaraka tsa tšepe tsa ferritic le austenitic. Phapang e kholo ke hore Super Duplex e na le litaba tse phahameng tsa molybdenum le chromium tse fanang ka thepa e kholoanyane chromium e phahameng e boetse e khothalletsa ho thehoa ha mekhahlelo e kotsi ea intermetallic, e nang le maikutlo a 475 ° C ka lebaka la pula ea α' e nang le chromium, le ho embrittlement ka sigma, chi le mekhahlelo e meng ka mocheso o phahameng.

Alloy 2507 (S32750) e boetse e na le naetrojene e phahameng, e sa khothalletseng ho thehoa ha austenite feela le ho eketsa matla, empa hape e liehisa ho thehoa ha mekhahlelo ea intermetallic e lekaneng ho lumella ho sebetsa le ho etsoa ha duplex grade.

Sehlopha se khetholloa ke khanyetso e ntle haholo ea chloride corrosion, e kopantsoeng le matla a phahameng haholo a mochine. E loketse haholo ho sebelisoa libakeng tse mabifi joalo ka metsi a leoatle a futhumetseng a chlorine le media e nang le asiti ea chloride.

Alloy 2507 (S32750) litšobotsi ke tse latelang:

● Ho hanyetsa ka mokhoa o babatsehang ho senya khatello ea kelello (SCC) libakeng tse nang le chloride
● Ho hanyetsa ka mokhoa o babatsehang ha ho senngoa ha likoti le likoti
● Ho hanyetsa ho hoholo ha kutu ka kakaretso
● Matla a phahameng haholo a mochine
● Lintho tsa 'mele tse fanang ka melemo ea moralo
● Ho hanyetsa ho hoholo ha khoholeho ea mobu le mokhathala oa ho senya
● Ho chesehela hantle

S32750 e etselitsoe lits'ebetso tse hlokang matla tse hlokang matla a ikhethang le ho hanyetsa kutu, tse fumanehang hots'ebetso ea lik'hemik'hale, lisebelisoa tsa petrochemical, le metsi a leoatle. E sebelisoa haholo lipatlisisong / tlhahisong ea oli le khase ea kantle ho naha le ho li-exchangers tsa mocheso ho petrochemical / chemical processing. Sehlopha se boetse se loketse lisebelisoa tsa hydraulic le lisebelisoa tsa lisebelisoa libakeng tsa leoatle tsa tropike.
