ASTM B424 UNS N08825 spacer ring super alloy flange
825 Nickel Alloy Sheet is used in industries such as air pollution control, chemical and petrochemical, food processing, nuclear energy, corrosion resistant applications in offshore oil and gas production, ore processing, petroleum refining, steel pickling and waste disposal.
Alloy 825 is resistant to corrosion in a variety of process environments, including sulfuric, sulfurous, phosphoric, nitric, hydrofluoric, and organic acids and bases such as sodium or potassium hydroxide, as well as acidic chloride solutions. Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. The chemical composition of this nickel steel alloy is designed to provide superior resistance to many corrosive environments. The outstanding characteristic of Incoloy 825 is its corrosion resistance.
