Monel 400 Flange

Monel 400 UNS N04400 W.Nr2.4360

The material Monel 400 is a solid solution alloy that contains nickel, copper, and small amounts of iron, manganese, and other trace elements. Monel 400 flanges are widely used in the chemical industry, oil and gas industry, marine applications, and other industries that require high strength and excellent corrosion resistance.

It is known for its superior resistance to a wide range of corrosive environments, including seawater, acidic and alkaline solutions, and high-temperature environments. Monel 400 has excellent mechanical properties and is easy to work with, making it a versatile material for use in flange applications.

The flange standards for Monel 400 include ANSI B16.5, ASME B16.47, and MSS-SP44. These flanges are available in a range of sizes, pressure ratings, and configurations such as slip-on, blind, threaded, and weld neck.
