2205 zitsulo zosapanga dzimbiri zophimbidwa ndi machubu

General Properties

Aloyi 2205 duplex zitsulo zosapanga dzimbiri mbale ndi 22% Chromium, 3% Molybdenum, 5-6% Nickel nayitrogeni aloyed duplex zosapanga dzimbiri mbale ndi mkulu wamba, m'dera ndi kupsinjika kukana dzimbiri kukana kuwonjezera mphamvu mkulu ndi kulimba kwambiri zotsatira.

2205 zitsulo zosapanga dzimbiri zophimbidwa ndi machubu

Aloyi 2205 duplex zitsulo zosapanga dzimbiri zimapereka kukana kwa dzimbiri ndi ming'alu kuposa 316L kapena 317L austenitic zitsulo zosapanga dzimbiri pafupifupi pafupifupi media zonse zowononga.Lilinso ndi dzimbiri ndi kukokoloka kutopa katundu komanso kutsika kutsika kwa matenthedwe ndi apamwamba matenthedwe conductivity kuposa austenitic.

Mphamvu zokolola zimakhala pafupifupi kawiri kuposa zazitsulo zosapanga dzimbiri za austenitic.Izi zimathandiza wopanga kuti achepetse kulemera kwake ndipo zimapangitsa kuti aloyi ikhale yokwera mtengo kwambiri poyerekeza ndi 316L kapena 317L.

2205 zitsulo zosapanga dzimbiri zophimbidwa ndi machubu

Aloyi 2205 duplex chitsulo chosapanga dzimbiri mbale ndi yoyenera makamaka ntchito zophimba -50°F/+600°F kutentha osiyanasiyana.Kutentha kwakunja kwamtunduwu kumatha kuganiziridwa koma kumafunikira zoletsa, makamaka zomangira zowotcherera.

Kukaniza kwa Corrosion

General Corrosion
Chifukwa cha kuchuluka kwa chromium (22%), molybdenum (3%), ndi nayitrogeni (0.18%), kukana kwa dzimbiri kwa 2205 duplex stainless steel plate ndiapamwamba kuposa 316L kapena 317L m'malo ambiri.

Localized Corrosion Resistance
Chromium, molybdenum, ndi nayitrogeni mu mbale ya 2205 duplex zosapanga dzimbiri imaperekanso kukana kwabwino kwambiri pakubowola ndi kuwononga kwapang'onopang'ono ngakhale munjira zopatsa oxidizing komanso acidic.

Isocorrosion Curves 4 mpy (0.1 mm/chaka), mu njira ya sulfuric acid yokhala ndi 2000 ppm

Stress Corrosion Resistance
Duplex microstructure imadziwika kuti imathandizira kukana kupsinjika kwa corrosion kwazitsulo zosapanga dzimbiri.

Chloride stress corrosion corrosion ya zitsulo zosapanga dzimbiri za austenitic zitha kuchitika pakafunika kutentha, kupsinjika kwamphamvu, mpweya, ndi ma chloride.Popeza izi sizimawongoleredwa mosavuta, kupsinjika kwa dzimbiri nthawi zambiri kumakhala cholepheretsa kugwiritsa ntchito 304L, 316L, kapena 317L.

Corrosion Kutopa Kukana
Aloyi 2205 duplex chitsulo chosapanga dzimbiri mbale imaphatikiza mphamvu yayikulu komanso kukana kwa dzimbiri kuti ipangitse kutopa kwakukulu.Mapulogalamu omwe zida zogwirira ntchito zimakhudzidwa ndi chilengedwe chowononga kwambiri komanso kukweza pazizungulire zitha kupindula ndi zomwe zili mu mbale ya 2205 duplex zitsulo zosapanga dzimbiri.
