Monel 400 UNS N04400 2.4360 Bar/Rod/Wire/Forging/Plate/Strip With Excellent Corrosion Resistance And Good Weldability

Monel® 400 (UNS N04400 / 2.4360) is a nickel-copper alloy renowned for its exceptional corrosion resistance, high strength, and excellent weldability. Composed of approximately 67% nickel and 30% copper, it offers outstanding resistance to seawater, acids, and alkaline environments, making it ideal for marine, chemical, and aerospace applications. Monel 400 wire, Monel 400 welding wire, and Monel filler wire are widely used in situations requiring both durability and corrosion resistance under harsh conditions.

Monel 400 retains its mechanical properties across a broad temperature range, with a melting point of 1,350–1,400°C. It exhibits good ductility, high fatigue strength, and excellent resistance to stress corrosion cracking. Common applications include heat exchangers, pumps, valves, piping systems, and fasteners exposed to aggressive environments. While Monel 400 can be hot- and cold-worked, its inherent toughness makes machining challenging. For optimal results in joining, Monel welding wire and Monel-compatible filler wires are recommended to ensure strong, corrosion-resistant welds.
