Kugwiritsa ntchito kwa Duplex Ss 2205
2205 chitsulo chosapanga dzimbiri 4 * 1mm capillary coiled chubing
Zina mwazomwe zimagwiritsidwa ntchito ndi duplex zitsulo zosapanga dzimbiri kalasi 2205 zalembedwa pansipa:
- Kufufuza mafuta ndi gasi
- Zida zopangira
- Transport, kusungirako, ndi kukonza mankhwala
- Kuchuluka kwa kloridi ndi malo am'madzi
- Makina opangira mapepala, akasinja amowa, zamkati, zogaya mapepala, etc.
Mawonekedwe a Duplex Ss 2205
2205 chitsulo chosapanga dzimbiri 4 * 1mm capillary coiled chubing
Duplex Stainless Steel 2205 Poyerekeza ndi 316L ndi 317L austenitic zosapanga dzimbiri zosapanga dzimbiri, 2205 ndiyopambana pakukana kutsekereza komanso kuwononga dzimbiri.Ili ndi kukana kwambiri kwa dzimbiri.Poyerekeza ndi austenite, mphamvu yake yowonjezera kutentha ndi yotsika, matenthedwe amatenthedwe ndi apamwamba.
Duplex Stainless Steel 2205 ili ndi mphamvu zopondereza za austenitic zosapanga dzimbiri, zomwe zimalola opanga kuchepetsa kulemera kwawo poyerekeza ndi 316L ndi 317L.Aloyi ya 2205 ndi yoyenera kugwiritsidwa ntchito mu -50 ° F / + 600 ° F kutentha osiyanasiyana ndipo ingagwiritsidwe ntchito pozizira kwambiri pansi pa zoletsedwa kwambiri (makamaka pomanga zitsulo).
Kukana kwa dzimbiri kwa 2205 Duplex Stainless Steel
2205 chitsulo chosapanga dzimbiri 4 * 1mm capillary coiled chubing
- Kuwonongeka kofanana, Kukana kwa chitsulo chosapanga dzimbiri cha duplex 2205 ndikwapamwamba kuposa 316L ndi 317L m'malo ambiri chifukwa cha chromium (22%), molybdenum (3%), ndi nitrogen (0.18%).
Zotsutsana ndi dzimbiri, Zomwe zili mu chromium, molybdenum, ndi nayitrogeni mu zitsulo zosapanga dzimbiri 2205 zimapangitsa kuti zisawonongeke kwambiri ndi ma pitting ndi corrosion mu njira za oxidizing ndi acidic. - Anti-stress corrosion, Kapangidwe ka 2205 duplex kachitsulo chosapanga dzimbiri kumathandiza kulimbitsa kukana kupsinjika kwa chitsulo chosapanga dzimbiri.Pa kutentha kwina, pansi pa zovuta, mpweya, ndi kloridi, chloride stress corrosion imapezeka muzitsulo zosapanga dzimbiri za austenitic.Popeza izi sizimayendetsedwa mosavuta, kugwiritsa ntchito 304L, 316L, ndi 317L ndizochepa pankhaniyi.
- Kutopa kwa anti-corrosion, chitsulo chapawiri-gawo 2205 mphamvu yayikulu komanso kukana kwa dzimbiri pakutopa kwamphamvu.Zipangizo zogwirira ntchito zimatha kutengeka ndi madera owononga komanso kutsitsa, ndipo mawonekedwe a duplex zosapanga dzimbiri 2205 ndizoyenera kugwiritsa ntchito izi.
Metallography za Duplex Ss 2205 uns s31803
Zomwe zimapangidwa ndi chitsulo cha 2205 duplex zimapereka mawonekedwe ofunikira a 50 ϫ / 50 pambuyo pa 1900 / 1922 ° F (1040 °C / 1080 ° C) njira yolimba yolumikizira.Ngati kutentha mankhwala kutentha ndi apamwamba kuposa 2000 ° F, kungachititse kuti kuwonjezeka ferrite zikuchokera.Monga zitsulo zina zosapanga dzimbiri zosapanga dzimbiri, ma aloyi 2205 amatha kugwa ndi mpweya wa intermetallic phase.
The intermetallic gawo precipitates pakati 1300 ° F ndi 1800 ° F ndi precipitates mofulumira pa 1600 ° F. Choncho, tiyenera kuyesa 2205, kuonetsetsa kuti palibe intermetallic gawo, mayeso buku ASTM A 923.
