Wosankhidwa ngati UNS N08825 kapena DIN W.Nr. 2.4858, Inkoloy 825 (yomwe imadziwikanso kuti "Alloy 825") ndi aloyi yachitsulo-nickel-chromium yokhala ndi zowonjezera za molybdenum, cooper ndi titaniyamu. Kuphatikizika kwa molybdenum kumakulitsa kukana kwake kuti zisawonongeke mu dzimbiri lamadzimadzi pomwe mkuwa umathandizira kukana sulfuric acid. Titaniyamu amawonjezeredwa kuti akhazikike. Aloyi 825 imakana kwambiri kuchepetsa komanso ma oxidizing zidulo, kupsinjika-kusweka kwa dzimbiri, komanso kuukira komweko monga kugwetsa ndi dzimbiri. Makamaka kugonjetsedwa ndi sulfuric ndi phosphoric acid. Aloyi ya inkoloy 825 imagwiritsidwa ntchito makamaka pokonza mankhwala, mapaipi a petrochemical, zida zowongolera kuipitsidwa, mapaipi amafuta ndi gasi, kukonzanso mafuta a nyukiliya, kupanga asidi, ndi zida zonyamula.
