2205 duplex chitsulo chosapanga dzimbiri chophimbidwa ndi chubu / capillary chubu

2205 Duplex mwachidule

Duplex 2205 ndi nayitrogeni wowonjezeraduplex chitsulo chosapanga dzimbiriyomwe idapangidwa kuti ithane ndi zovuta za dzimbiri zomwe zimakumana ndi zitsulo zosapanga dzimbiri 300."Duplex" ikufotokoza za banja lazitsulo zosapanga dzimbiri zomwe sizikhala bwino, monga 304 zosapanga dzimbiri, kapena ferritic, ngati 430 zosapanga dzimbiri.Mapangidwe a 2205 duplex zitsulo zosapanga dzimbiri amakhala ndi maiwe austenite ozunguliridwa ndi gawo lopitilira la ferrite.Mu chikhalidwe cha annealed, 2205 ili ndi pafupifupi 40-50% ferrite.Nthawi zambiri amatchedwa giredi ya kavalo, 2205 ndiye giredi yomwe imagwiritsidwa ntchito kwambiri m'banja la duplex lazitsulo zosapanga dzimbiri.

2205 duplex chitsulo chosapanga dzimbiri chophimbidwa ndi chubu / capillary chubu

Ubwino wa mawonekedwe a duplex ndikuti umaphatikiza mikhalidwe yabwino ya aloyi ya ferritic (kupsinjika kwa corrosion cracking resistance ndi mphamvu yayikulu) ndi ya austenitic alloy (zosavuta kupanga ndi kukana dzimbiri).

Kukaniza kwa Corrosion

2205 duplex chitsulo chosapanga dzimbiri ndi njira yotsika mtengo pakugwiritsa ntchito ambiri pomwe zitsulo zosapanga dzimbiri 300 zitha kutengeka ndi chloride stress corrosion cracking.Kupsyinjika kwa dzimbiri kumachitika pamene zitsulo zosapanga dzimbiri zili ndi kupsinjika kwamphamvu, pomwe zimagwirizana ndi njira zomwe zili ndi ma chloride.Kutentha kowonjezereka kumawonjezeranso kutengeka kwa zitsulo zosapanga dzimbiri kuti zitsimikize kung'ambika kwa dzimbiri.

Kuphatikizika kwa chromium, molybdenum ndi nayitrojeni kumapereka kukana kwabwino kwa 2205 ku pitting ya kloridi ndi dzimbiri.Kukana kumeneku ndikofunikira kwambiri pazantchito monga madera am'madzi, madzi amchere, ma bleaching, njira zotsekera zamadzi otsekeka komanso ntchito zina zopangira chakudya.Zomwe zili mu chromium, molybdenum ndi nayitrogeni mu 2205 zimapereka kukana kwa dzimbiri kuposa zitsulo zosapanga dzimbiri, monga, 316L ndi 317L m'malo ambiri.

Mapangidwe a Chemical,%

2205 duplex chitsulo chosapanga dzimbiri chophimbidwa ndi chubu / capillary chubu

Kodi mawonekedwe a Duplex 2205 ndi ati?

• Kukana kwakukulu kwa kloride stress corrosion cracking
• Kukana kwa chloride pitting ndi ming'alu dzimbiri
• Good general corrosion resistance
• Zabwino sulfide stress corrosion resistance
• Mphamvu Zapamwamba
• Weldability wabwino ndi ntchito

Ndi mapulogalamu ati omwe Duplex 2205 amagwiritsidwa ntchito?

• Chemical process ziwiya, mapaipi ndi kutentha exchanger
• Zida zopangira mphero, zochapira mabuleshi, ziwiya za chip pre-steaming
• Zida zopangira chakudya
• Kupaka mapaipi amafuta ndi osinthanitsa kutentha
• Flue gasi desulfurization zida
