ASTM B564 UNS N04400 Weld Neck Flanges ASME B16.5 WNRF Flanges
ASTM B564 UNS N04400 slip-on flanges (ASME B16.5 WNRF) are high-strength, corrosion-resistant metal fittings made from Monel 400, an alloy known for its excellent performance in corrosive and high-temperature environments. Designed to ASME B16.5 standards, they are available in a variety of sizes and pressure ratings and, due to their permanently welded connection, are fully inspectable, making them an ideal choice for high-pressure systems.
What is ASTM B564 UNS N04400 material?
ASTM B564 UNS N04400 flanges, also known as Monel alloy 400, are a nickel-based alloy with a certain amount of copper added. ASTM B564 UNS N04400 flanges typically exhibit high tensile strength over a wide temperature range, up to 1000 degrees Fahrenheit (approximately 477 degrees Celsius).

Materials and Properties
Monel 400 (UNS N04400): This nickel-copper alloy offers excellent corrosion resistance, including resistance to seawater, acids, and stress corrosion cracking, while maintaining high tensile strength over a wide temperature range.
Standards and Design
ASTM B564: This specification covers the manufacture of wrought nickel alloy products, including flanges.
ASME B16.5: This standard specifies dimensional requirements for various flanges, including weld neck flanges, to ensure compatibility with standard piping systems.
Weld neck flange design: The flange's long neck design allows for direct welding to the pipe, creating a secure, permanent joint that can be fully radiographically inspected.
Key Properties
Corrosion Resistance: Highly resistant to pitting, stress corrosion, and harsh chemicals.
High-Temperature Applications: Performs well in both high and low-temperature conditions.
High-Pressure Applications: Preferred for high-pressure and hazardous applications due to the integrity of the welded joint.
Applications
These flanges are commonly used in demanding industries, including offshore engineering, seawater piping systems, petrochemical and chemical processing, and applications involving harsh chemicals or corrosive environments.
