ALLOY 825 (UNS N08825 / W.Nr. 2.4858)

Common trade names: INCOLOY® alloy 825

Alloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. Is designed to provide exceptional resistance to many corrosive environments. The nickel content is sufficient for resistance to chloride-ionstress-corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acids. The molybdenum also aids resistance to pitting and crevice corrosion. The alloy’s chromium content confers resistance to a variety of oxidizing substances such as nitric acid, nitrates and oxidizing salt. The titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion. The resistance of Alloy 825 to general and localized corrosion under diverse conditions gives the alloy broad usefulness. .

Corrosion resistantThe outstanding attribute of Alloy 825 is its high level of corrosion resistance. In both reducing and oxidize environments, the alloy resists general corrosion, pitting, crevice corrosion, intergranular corrosion, and stress-corrosion cracking. Some environments in which Alloy 825 is particularly useful are sulfuric acid, phosphoric acid, sulfurcontaining flue gases, sour gas and oil wells, and sea water

Applications of ALLOY 825 (UNS N08825 / W.Nr. 2.4858)

Applications include chemical processing, pollution control, oil and gas recovery, acid production, pickling operations, nuclear fuel reprocessing, and handling of radioactive wastes
