NC1239 Incoloy 825 (Alloy 825, UNS N08825) Wire

Incoloy 825 (Alloy 825, UNS N08825) Wire Description:

Incoloy alloy is also a range of superalloys produced by Special Metals Corporation. They are nickel-iron-chromium alloys that are used for applications that require high corrosion resistance and high-temperature strength. Incoloy alloys are quite similar to Inconel alloys but their different composition makes some distinctions in their applications.
Alloy 825 is a Nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The alloy's 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.

Other trade names: Alloy 825, Nickelvac 825, Nicrofer 4241
