ASTM B564 Monel R405 Flanges are high performance nickel-copper alloy flanges with excellent corrosion resistance especially in marine and chemical environments. These flanges are made from UNS N04405 and are manufactured to ASTM B564 with added sulfur for enhanced machinability. They are widely used in marine applications, offshore piping systems and chemical processing industries where durability and resistance to seawater corrosion is critical.
Introduction to ASTM B564 Monel R405 Flanges
Monel R405 Flanges are an economical and durable solution for reliable piping connections in corrosive environments. The flanges are made from a free-machining grade of Monel 400 to provide better machinability without sacrificing corrosion resistance.
We are manufacturing and providing ASTM B564 UNS N04405 Forged Flanges that are made to work in extreme conditions such as exposure to sea water, acidic conditions and high pressure systems. Whether you operate offshore platforms or chemical plants these flanges deliver a reliable seal and a long service life.

What is Monel R405?
Monel Alloy R405 Flange is nickel copper alloy with small addition of sulfur to improve machinability. R405 is easier to machine than Monel 400, but is slightly less weldable. Key Characteristics:
- Excellent resistance to seawater corrosion
- Good mechanical strength
- High resistance to stress corrosion cracking
- Suitable for marine and chemical industries
- Improved machinability due to sulfur
This makes monel R405 high strength flanges for marine applications highly reliable in seawater and offshore conditions.
