Nsomba zosapanga dzimbiril F55 ndi duplex (austenitic-ferritic) chitsulo chosapanga dzimbiri chomwe chili ndi pafupifupi 40 - 50% ferrite mu chikhalidwe cha annealed.F55 yakhala yankho lothandiza ku zovuta za chloride stress corrosion ndi 304/304L kapena 316/316L zosapanga dzimbiri.Zomwe zili pamwamba pa chromium, molybdenum ndi nayitrogeni zimapereka kukana kwa dzimbiri kuposa 316/316L ndi 317L zosapanga dzimbiri m'malo ambiri.F55 sichikuperekedwa kuti igwire ntchito kutentha mpaka 600 ° F

F55(S32760) imaphatikiza mphamvu zamakina apamwamba komanso ductility yabwino ndi kukana dzimbiri kumadera am'madzi ndipo imagwira ntchito mozungulira komanso paziro.High kukana abrasion, kukokoloka ndi cavitation kukokoloka ndi ntchito wowawasa ntchito ntchito
Amagwiritsidwa ntchito makamaka ngati mafuta & gasi ndi ntchito zam'madzi zomwe zimagwiritsidwa ntchito ngati zotengera zokakamiza, mavavu amatsamwitsa, mitengo ya Khrisimasi, ma flanges ndi mapaipi.
