I-alloy 2507, kunye nenombolo ye-UNS i-S32750, i-alloy yesigaba sesibini esekelwe kwi-iron-chromium-nickel system kunye nesakhiwo esixutywe malunga nemilinganiselo elinganayo ye-austenite kunye ne-ferrite. Ngenxa yolungelelwaniso lwesigaba se-duplex, i-alloy 2507 ibonisa ukuxhathisa okugqwesileyo kwi-corrosion jikelele efana ne-austenitic stainless steels kunye nezinto ezifanayo zokudibanisa. Ngaphandle koko, inokuqina okuphezulu kunye namandla emveliso kunye nokuchasana kwe-Chloride ye-SCC engcono kakhulu kune-austenitic esebenza nayo ngelixa igcina ukuqina kwempembelelo engcono kune-ferritic efanayo.
