Alloy 825

Alloy 825/ Incoloy 825/ N08825/ 2.4858

Alloy 825 is a highly versatile nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. Its carefully balanced chemical composition, provides exceptional resistance to a wide range of corrosive environments. The alloy’s high nickel content ensures excellent resistance to chloride-ion stress-corrosion cracking, while the combination of nickel, molybdenum, and copper enhances its performance in reducing environments, including those containing sulfuric and phosphoric acids.

Molybdenum further strengthens the alloy’s resistance to pitting and crevice corrosion, while chromium contributes to its durability in oxidizing environments such as those containing nitric acid, nitrates, and oxidizing salts. The addition of titanium, when paired with appropriate heat treatment, stabilizes the alloy against sensitization and intergranular corrosion, ensuring long-term reliability in demanding applications.

Due to its outstanding resistance to both general and localized corrosion, Alloy 825 is widely used across various industries. Key applications include chemical processing, pollution control, oil and gas recovery, acid production, pickling operations, nuclear fuel reprocessing, and the handling of radioactive waste. Its performance characteristics make it a preferred choice for applications similar to those of Alloy 020, offering durability and corrosion resistance in extreme conditions.
