2205 ni duplex (austenitis-ferritic) ibyuma bitagira umwanda birimo ferrite igera kuri 40 - 50% muburyo bwa annealed. 2205 yabaye igisubizo gifatika kubibazo bya chloride yibibazo byangirika byatewe na 304 / 304L cyangwa 316 / 316L bitagira umwanda. Chromium ndende, molybdenum hamwe na azote itanga kurwanya ruswa iruta 316 / 316L na 317L idafite umwanda mubidukikije byinshi. 2205 ntabwo isabwa kubushyuhe bwo gukora hejuru ya 600 ° F.
Igishushanyo mbonera cya 2205 kiri hejuru cyane ya 316 / 316L, akenshi yemerera kubaka urukuta rworoshye. 2205 ifite ingaruka nziza zikomeye kugeza ku bushyuhe buri munsi - 40 ° F. 2205 isudira hamwe na E2209 cyangwa ER2209 yuzuza.
