Monel 400 is a nickel-copper alloy (about 67% Ni – 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good corrosion resistance, good weldability and high strength. Monel 400 is a alloy with high strength and toughness and remains ductile even at subzero temperatures. Age-hardening treatments are not required to obtain the high strength properties of Monel 400 because it is a solid-solution alloy that is hardened only through cold working. The alloy is resistant to corrosion in many reducing environments, offering excellent corrosion resistance in seawater, hydrofluoric acid, sulfuric acid, and hydrochloric acid. Monel 400 also shows resistance to stress corrosion cracking and pitting in fresh water, is resistant to oxidization and can operate from cryogenic temperatures to 500°F (260°C). Its wide use in marine applications and other non-oxidizing chloride solutions.
Monel 400 flanges are high-strength, corrosion-resistant components that are used for a variety of industrial applications. They are primarily made from nickel and copper, making them ideal for seawater and steam environments. Monel 400 flanges provide superior strength and toughness when exposed to extreme temperatures or corrosive environments such as saltwater spray or sea air. Compared to other steel alloys, these flanges also have exceptional weldability, machinability, formability, and ductility. The Monel 400 Flanges possess superior strength and have outstanding resistance against chloride stress corrosion cracking. These flange have a density of 8.80 g/cm3 and have a melting point between 1300 to 1350 degrees C. Alloy 400 Flanges have good weldability and are seen in marine oxidizing environments. These flange have enhanced mechanical properties and possess a hardness between 125 to 215 Brinell. They possess a thermal conductivity of 22 W/mK.
The blind flanges are used to close a connection while the slip on flanges are used to adjust a connection position. The ASTM B564 Monel 400 Slip On Flanges allow the seamless pipes to slip onto them so the positioning becomes easy. There are welded flanges as well as threaded flanges. The Monel Alloy 400 Threaded Flanges are fitted with pipes with threads. The male threads on the pipe ends fit with the female threads on the threaded flanges. The ASME SB564 Alloy 400 Socket Weld Flanges are usually welded onto the pipes. The socket holds the pipes together during and after welding. Another commonly used type is the ring type joint 400 Monel RTJ Flange. It is used in two halves as two rings and is welded to the pipes. We supply all different kinds of flanges in the monel 400 material grade such as the ASTM B564 UNS N04400 Weld Neck Flange and other types.
