ASTM B564 UNS N08825 Flange

INCOLOY825/UNS N08825/Alloy825/2.4858

Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion.

Alloy 825 is especially resistant to sulfuric and phosphoric acids. This nickel steel alloy is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.

The UNS N08825 Flange is designed to be used in high-temperature and high-pressure applications, where corrosion resistance is critical. The flange is manufactured to meet specific industry standards, including the ASME B16.5 and ASTM B564 standards. It is available in various sizes, dimensions, and types such as socket weld, weld neck, slip-on, threaded, lap joint, and blind.

In what forms is Incoloy 825 available?
• Sheet
• Plate
• Bar
• Pipe & Tube (welded & seamless)
• Fittings (i.e. flanges, slip-ons, blinds, weld-necks, lapjoints, long welding necks, socket welds, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples)

Alloy 825 (UNS N08825) Chemical Composition, %

Incoloy 825 flange has highly resistant to stress corrosion cracking, pitting, and crevice corrosion, they have a wide range of applications, including in chemical processing plants, oil refineries, desalination plants, power generation, and water treatment facilities. It is used in a variety of applications, including heat exchangers, process piping, and storage tanks. The flange is also commonly used in marine applications, where its corrosion resistance makes it ideal for use in seawater environments.
