Koho ʻia ʻo UNS N08825 a i ʻole DIN W.Nr. 2.4858, Incoloy 825 (ʻike ʻia ʻo "Alloy 825") he hao-nickel-chromium alloy me nā hoʻohui o ka molybdenum, cooper a me ka titanium. ʻO ka hoʻohui molybdenum e hoʻomaikaʻi i kona kūʻē ʻana i ka hoʻopaʻa ʻana i ka ʻino i loko o ka noi ʻana i ka wai a ʻo ka mea keleawe e hāʻawi i ke kūʻē i ka sulfuric acid. Hoʻohui ʻia ka Titanium no ka hoʻopaʻa ʻana. He kūpaʻa maikaʻi loa ka Alloy 825 i nā ʻakika hoʻohaʻahaʻa a me ka hoʻoheheʻe ʻana, i ka haki ʻana i ke koʻikoʻi-corrosion, a me ka hoʻouka kaua kūloko e like me ka pitting a me ka crevice corrosion. He kūʻokoʻa ia i ka sulfuric a me ka phosphoric acid. Hoʻohana nui ʻia ʻo Incoloy 825 alloy no ka hoʻoili ʻana i ke kemika, ka paipu petrochemical, nā mea hoʻomalu pollution, ka ʻaila a me ka paipu kinoea, ka hoʻoponopono hou ʻana i ka wahie nuklea, ka hana ʻana i ka waikawa, a me nā lako pickling.
