I-stainless steel I-F55 iyinsimbi engagqwali eyi-duplex (austenitic-ferritic) equkethe cishe u-40 - 50% we-ferrite esimweni esifakwe emanzini.I-F55 ibe yisixazululo esisebenzayo sezinkinga zokuqhekeka kwe-chloride stress corrosion ezitholwe ku-304/304L noma 316/316L okungenasici.Okuqukethwe okuphezulu kwe-chromium, i-molybdenum ne-nitrogen kunikeza ukumelana nokugqwala okungaphezu kuka-316/316L no-317L ngaphandle kwebala ezindaweni eziningi.I-F55 ayisikiselwanga kumazinga okushisa okusebenza afika ku-600°F

I-F55(S32760 ) ihlanganisa amandla emishini aphezulu kanye ne-ductility enhle nokumelana nokugqwala ezindaweni zasolwandle futhi isebenza emazingeni okushisa azungezile nangaphansi kweziro.Ukumelana okuphezulu nokuhuzuka, ukuguguleka nokuguguleka kwe-cavitation futhi kusetshenziselwa ukusebenza kwenkonzo emuncu
Ngokuyinhloko isetshenziselwa uwoyela negesi kanye nezicelo zasolwandle ezisetshenziselwa imikhumbi yokucindezela, ukuklinywa kwama-valve, izihlahla zikaKhisimusi, ama-flanges kanye nomsebenzi wamapayipi.
