Bir aan lahaynl F55 waa bir-duplex (austenitic-ferritic) bir aan lahayn oo ka kooban qiyaastii 40 - 50% ferrite xaalad la tirtiray.F55 waxay xal wax ku ool ah u noqotay dhibaatooyinka dildilaaca daxalka ee 304/304L ama 316/316L.chromium-ka sare, molybdenum iyo nitrogen waxa ku jira waxay bixiyaan iska caabin daxalka ka sarreeya 316/316L iyo 317L aan lahayn deegaan badi.F55 laguma soo jeedin heerkulka shaqaynta ilaa 600°F

F55(S32760) wuxuu isku daraa xoog farsamo sare leh iyo ductility wanaagsan leh iska caabinta daxalka ee bay'ada badda waxayna ku qabataa heerkulka jawiga iyo eber hoose.Iska caabbinta sare ee nabaad-guurka, nabaad guurka iyo cavitation iyo sidoo kale loo isticmaalo hawlgalka adeegga dhanaan
Inta badan loo isticmaalo saliida & gaaska iyo codsiyada badda oo sida caadiga ah loo isticmaalo weelasha cadaadiska, ceejiska valves, geedaha xmaska, garabka iyo tuubooyinka
