Descriptions of INCOLOY 825
Alloy 825 is a Nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. The alloys chemical composition provides exceptional resistance to many corrosive environments.
The Nickel content is sufficient for resistance to Chloride-ion stress corrosion cracking. The nickel, combined with molybdenum and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acid. The molybdenum also aids resistance to pitting and crevice corrosion. The alloy Chromium content confers resistance to a variety of oxidizing substances such as nitric acid, nitrates and oxidizing salts. The titanium addition, with appropriate heat treatment, will stabilize the alloy against sensitization to intergranular corrosion.
