Yagenwe nka UNS N08825 cyangwa DIN W.Nr. 2.4858, Incoloy 825 (izwi kandi nka “Alloy 825”) ni icyuma-nikel-chromium kivanze hiyongereyeho molybdenum, koperative na titanium. Kwiyongera kwa molybdenum kunoza uburyo bwo kurwanya ruswa mu mazi yo kwangirika mu gihe umuringa utanga aside irike. Titanium yongeweho kugirango ituze. Alloy 825 ifite imbaraga zo kurwanya acide na okiside, kugabanuka kwa ruswa, no kugaba ibitero byaho nko gutobora no kwangirika. Irwanya cyane cyane acide sulfurike na fosifori. Incoloy 825 ikoreshwa cyane cyane mugutunganya imiti, imiyoboro ya peteroli, ibikoresho byo kurwanya umwanda, imiyoboro ya peteroli na gaze, kongera ingufu za peteroli, kongera aside, nibikoresho byo gutoragura.
