I-stainless steel I-F55 i-duplex (i-austenitic-ferritic) insimbi engenasici equkethe malunga ne-40 - 50% ye-ferrite kwimeko edibeneyo.I-F55 ibe sisisombululo esisebenzayo kwi-chloride yoxinzelelo lweengxaki zokuqhekeka kwe-corrosion kunye ne-304 / 304L okanye i-316 / 316L engenasici.I-chromium ephezulu, i-molybdenum kunye neziqulatho ze-nitrogen zibonelela ngokumelana nokubola okungaphezulu kwe-316 / 316L kunye ne-317L i-stainless kwiindawo ezininzi.I-F55 ayicetyiswa kubushushu bokusebenza ukuya kuthi ga kwi-600°F

I-F55(S32760) idibanisa amandla omatshini aphezulu kunye ne-ductility efanelekileyo kunye nokuxhathisa ukubola kwiindawo ezihlala elwandle kwaye iqhuba kwi-ambient kunye namaqondo obushushu angaphantsi kwe-zero.Ukuchasana okuphezulu kwi-abrasion, ukhukuliseko kunye ne-cavitation erosion kwaye isetyenziselwa ukusebenza kwenkonzo emuncu
Isetyenziselwa ikakhulu kwi-oyile kunye negesi kunye nezicelo zaselwandle eziqhele ukusetyenziselwa iinqanawa zoxinzelelo, iivalvu ezikrwitshwayo, imithi yeKrisimesi, iiflange kunye nemibhobho.
