E khethiloe joalo ka UNS N08825 kapa DIN W.Nr. 2.4858, Inkoloy 825 (eo hape e tsejoang e le "Alloy 825") ke motsoako oa tšepe-nickel-chromium o nang le litlatsetso tsa molybdenum, cooper le titanium. Keketso ea molybdenum e ntlafatsa ho hanyetsa ha eona ho corrosion ea sekoti ka har'a ts'ebeliso ea metsi a metsi ha koporo e fana ka khanyetso ho asiti ea sulfuric. Titanium e eketsoa bakeng sa botsitso. Alloy 825 e na le khanyetso e ntle ho li-acid tse fokotsang le ho oxidizing, ho phatloha ha khatello ea maikutlo, le tlhaselong ea lehae joalo ka pitting le crevice corrosion. Haholo-holo e hanyetsana le sulfuric le phosphoric acid. Incoloy 825 alloy e sebelisoa haholo bakeng sa ts'ebetso ea lik'hemik'hale, lipeipi tsa petrochemical, lisebelisoa tsa taolo ea tšilafalo, lipeipi tsa liliba tsa oli le khase, ho lokisa mafura a nyutlelie, tlhahiso ea asiti le lisebelisoa tsa ho kha.
