Stainless steel F55 i duplex (austenitic-ferritic) simbi isina tsvina ine inenge 40 - 50% ferrite mumamiriro ekugadzirisa.F55 yanga iri mhinduro inoshanda kune chloride stress corrosion cracking matambudziko anowanikwa ne304/304L kana 316/316L isina tsvina.Iyo yakakwira chromium, molybdenum uye nitrogen zviri mukati zvinopa kushorwa kwepamusoro kupfuura 316/316L uye 317L isina tsvina munzvimbo zhinji.F55 haina kukurudzirwa kushanda tembiricha inosvika 600°F

F55(S32760) inosanganisa simba remuchina uye yakanaka ductility pamwe nekudzivirira ngura kune nharaunda dzemugungwa uye inoita pane ambient uye sub zero tembiricha.Kupokana kwakakwirira kune abrasion, erosion uye cavitation erosion uye zvakare inoshandiswa mukuita basa rinovava
Inonyanya kushandiswa kuoiri & gasi uye zvikumbiro zvemugungwa zvinowanzo shandiswa kumanikidza midziyo, mavharuvhu anodzipa, miti yeXmas, flanges uye pombi.
