Ichongwe njenge-UNS N08825 okanye iDIN W.Nr. I-2.4858, i-Incoloy 825 (eyaziwa nangokuthi "i-Alloy 825") i-iron-nickel-chromium alloy kunye nezongezo ze-molybdenum, i-cooper kunye ne-titanium. Ukongezwa kwe-molybdenum kuphucula ukuxhathisa kwayo kwi-pitting corrosion kwi-aqueous corrosion application ngelixa umxholo wobhedu unika ukuxhathisa kwi-asidi ye-sulfuric. I-Titanium yongezwa ukuzinzisa. I-Alloy 825 inokumelana okugqwesileyo kokubini ekunciphiseni kunye ne-oxidizing acids, kuxinzelelo lwe-corrosion cracking, kunye nohlaselo lwasekhaya olufana ne-pitting kunye ne-crevice corrosion. Inganyangeki ngakumbi kwi-sulfuric kunye ne-phosphoric acids. I-Incoloy 825 ialloy isetyenziselwa ikakhulu ukusetyenzwa kweekhemikhali, imibhobho yepetrochemical, izixhobo zokulawula ungcoliseko, imibhobho ye-oyile nerhasi yomthombo, ukulungiswa kwakhona kwamafutha enyukliya, ukuveliswa kweasidi, kunye nezixhobo zokuchola.
