ASTM B564 Monel 400 flanges are high-performance forged nickel-copper alloy flanges designed for demanding corrosive environments. With excellent resistance to seawater, hydrofluoric acid, and alkaline media, Monel 400 is widely used in marine engineering, chemical processing, and offshore oil & gas industries.
Manufactured in accordance with ASTM B564 / ASME SB564, these flanges offer reliable mechanical strength and long service life under both oxidizing and reducing conditions.
Material Specification – Monel 400 (UNS N04400)
Monel 400 is a solid-solution nickel-copper alloy with the following typical composition:
Nickel (Ni): ≥ 63%
Copper (Cu): 28–34%
Iron (Fe): ≤ 2.5%
Manganese (Mn), Silicon (Si): trace elements
This composition provides excellent corrosion resistance, especially in seawater and chemical environments.
Applicable Standards
Material Standard: ASTM B564 / ASME SB564
Dimensional Standard: ASME B16.5 / ASME B16.47 / EN 1092-1
Excellent resistance to seawater and marine atmosphere corrosion
Strong resistance to hydrofluoric acid and alkalis
Good resistance to stress corrosion cracking
High mechanical strength over wide temperature range
Good weldability and fabrication performance
Applications
Monel 400 flanges are widely used in:
Offshore oil and gas platforms
Marine engineering and seawater systems
Chemical and petrochemical plants
Heat exchangers and condensers
Pumps, valves, and pipeline systems
Desalination and seawater cooling systems
Advantages
Long service life in highly corrosive environments
Stable performance in chloride-rich media
Reduced maintenance and replacement cost
Reliable sealing performance under pressure conditions
Supply Condition
We supply Monel 400 flanges in various sizes, pressure classes, and facing types including RF, FF, and RTJ, according to customer requirements.
Inspection and testing can be provided upon request, including PMI, UT, RT, and hydrostatic testing.
