Yakasarudzwa seUNS N08825 kana DIN W.Nr. 2.4858, Incoloy 825 (inozivikanwawo se "Alloy 825") isimbi-nickel-chromium alloy ine mawedzero emolybdenum, cooper uye titanium. Iyo molybdenum yekuwedzera inonatsiridza kuramba kwayo kugomba corrosion mune aqueous corrosion application nepo mhangura yemukati ichipa kuramba sulfuric acid. Titanium inowedzerwa kuti igadzikane. Iyo Alloy 825 ine yakanakisa kupikisa kune ese ekudzikisa uye oxidizing asidhi, kune kushushikana-kupwanya kwekupwanya, uye kurwiswa kwenzvimbo sekunge gomba uye kukoromoka. Inonyanya kupikisa sulfuric uye phosphoric acids. Incoloy 825 alloy inonyanya kushandiswa kugadzira makemikari, petrochemical pombi, midziyo yekudzora kusvibiswa, mafuta uye gasi pombi yetsime, kugadzira mafuta enyukireya, kugadzirwa kweasidhi, uye midziyo yekunhonga.
