• Introduction
  • INCOLOY 825 is a nickel-iron-chromium  alloy with additions of molybdenum, copper, and titanium. The alloy’s chemical  composition, given in Table 1, is designed to provide exceptional resistance  to many corrosive environments. The nickel content is sufficient for resistance  to chloride-ion stress-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 INCOLOY 825 to  general and localized corrosion under diverse conditions gives the alloy  broad usefulness. Applications include chemical processing, pollution  control, oil and gas recovery, acid production, pickling operations, nuclear fuel  reprocessing, and handling of radioactive wastes. Applications for alloy 825  are similar to those for INCOLOY alloy 020.
