Ti ṣe apẹrẹ bi UNS N08825 tabi DIN W.Nr. 2.4858, Incoloy 825 (ti a tun mọ ni "Alloy 825") jẹ irin-nickel-chromium alloy pẹlu awọn afikun ti molybdenum, cooper ati titanium. Afikun molybdenum ṣe ilọsiwaju resistance rẹ si ipata pitting ni ohun elo ipata olomi lakoko ti akoonu Ejò funni ni resistance si sulfuric acid. Titanium ti wa ni afikun fun imuduro. Alloy 825 ni atako ti o dara julọ si idinku mejeeji ati awọn acids oxidizing, si idamu-ibajẹ aapọn, ati si ikọlu agbegbe bi pitting ati ipata crevice. O jẹ paapaa sooro si sulfuric ati phosphoric acids. Incoloy 825 alloy jẹ lilo ni akọkọ fun sisẹ kemikali, fifin petrochemical, ohun elo iṣakoso idoti, epo ati gaasi pipii gaasi, atunṣe epo iparun, iṣelọpọ acid, ati ohun elo yiyan.
