ASME B16.5 ASTM B564 UNS N08825 / Incoloy 825 WNRF Flange Nickel Alloy Steel Flange​

Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. It offers excellent corrosion resistance in various environments, particularly in acidic and chloride-containing solutions. Incoloy 825 flanges are commonly used in industries such as chemical processing, oil and gas, marine engineering, and more. Incoloy 825 flanges are preferred when there is a need for resistance to pitting, crevice corrosion, and stress-corrosion cracking.

The Advantage of Using Nickel Alloy Materials:

1. Corrosion Resistance: Nickel alloys like Incoloy 825 exhibit exceptional resistance to corrosion in aggressive environments, including acidic solutions, chloride-containing media, and corrosive gases. This corrosion resistance ensures the longevity and reliability of the piping system.

2. High Temperature Resistance: Nickel alloy flanges can withstand high temperatures without losing their mechanical properties. This makes them suitable for applications where elevated temperatures are present, such as in high-temperature processing industries.

3. Strength and Toughness: Nickel alloy materials provide excellent strength, toughness, and ductility, making them capable of withstanding high mechanical stresses and pressure fluctuations in industrial systems.

4. Creep Resistance: Nickel alloys have excellent creep resistance, allowing them to maintain their structural integrity and dimensional stability even under prolonged exposure to high temperatures and loads.

5. Compatibility: Nickel alloy flanges are compatible with a wide range of process fluids, making them versatile and suitable for use in various industries, including chemical processing, petrochemical, power generation, and offshore applications.

6. Weldability: Nickel alloys like Incoloy 825 are generally weldable using common welding techniques, allowing for ease of fabrication and installation of piping systems.

7. Long Service Life: Due to their excellent corrosion resistance, temperature resistance, and mechanical properties, nickel alloy flanges can have a longer service life compared to flanges made from other materials, reducing maintenance and replacement costs in the long run.
