Iqokwe njenge-UNS N08825 noma i-DIN W.Nr. 2.4858, I-Incoloy 825 (eyaziwa nangokuthi “i-Alloy 825”) iyingxube ye-iron-nickel-chromium enezengezo ze-molybdenum, i-cooper ne-titanium. Isengezo se-molybdenum sithuthukisa ukumelana kwayo nokugqwala kokugqwala ekugxumeni kwe-aqueous corrosion kuyilapho okuqukethwe kwethusi kunikeza ukumelana ne-sulfuric acid. I-Titanium yengezwa ukuze kuqiniswe. I-Alloy 825 inokumelana okuhle kakhulu nakho kokubili ukunciphisa kanye ne-oxidizing acid, ukuqhekeka kwe-stress-corrosion, kanye nokuhlaselwa kwendawo okufana nokugqwala nokugqwala kwemifantu. Imelana ikakhulukazi ne-sulfuric ne-phosphoric acid. Ingxubevange ye-Incoloy 825 isetshenziselwa ikakhulukazi ukucutshungulwa kwamakhemikhali, amapayipi e-petrochemical, okokulawula ukungcoliswa komhlaba, amapayipi omthombo kawoyela negesi, ukucutshungulwa kabusha kukaphethiloli wenuzi, ukukhiqizwa kwe-asidi, nemishini yokucosha.
