Forged Monel 400 WNRF Flange ASTM B564 UNS N04400 Nickel Alloy Steel Flanges

ANSI B16.5 ASTM B564 Monel 400 / UNS N04400 Nickel Alloy Flange WNRF Flange

Monel 400, which is a nickel-copper alloy known for its high strength and excellent corrosion resistance. It typically contains around 67% nickel and 30% copper, with small amounts of other elements such as iron, manganese, silicon, and carbon. WNRF flanges feature a long and tapered neck that is welded to the pipe. This design allows for a smooth flow of fluids, reduces turbulence, and provides a strong connection. The neck also acts as a reinforcement, making WNRF flanges suitable for high-pressure and high-temperature applications. The flanges have a raised face on the connection surface. This raised portion provides additional sealing surface and helps prevent leakage.

Some Key Details About ASTM B564 Monel 400 Flanges

1. Composition: Monel 400 is a nickel-copper alloy known for its high strength and excellent corrosion resistance. It primarily consists of approximately 67% nickel and 23% copper, with small amounts of iron, manganese, and silicon.

2. Corrosion Resistance: Monel 400 flanges exhibit exceptional resistance to various corrosive environments, including seawater, acids (sulfuric, hydrofluoric, etc.), alkaline solutions, and reducing agents. This makes them suitable for applications in marine, chemical, and oil refining industries.

3. High-Temperature Strength: Monel 400 retains its strength and resistance to oxidation at elevated temperatures. It offers good mechanical properties up to temperatures of about 1000°F (540°C), making it suitable for high-temperature applications like steam lines and heat exchangers.

4. Non-Magnetic: Unlike many other nickel alloys, Monel 400 is non-magnetic, making it desirable for applications where magnetic interference or interaction should be avoided, such as in electronic and aerospace industries.

5. Toughness and Ductility: Monel 400 exhibits excellent toughness and ductility even at low temperatures, making it suitable for cryogenic applications.

6. Weldability: Monel 400 flanges can be easily welded using various processes, including gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). It is important to follow appropriate welding procedures to maintain the corrosion resistance of the alloy.

7. Application Areas: Monel 400 flanges are commonly used in industries such as offshore and marine, chemical processing, oil and gas, desalination plants, and heat exchangers. They are widely employed for connecting pipes, valves, and equipment in these industries.
