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 known for its excellent corrosion resistance, high strength, and good weldability. It consists of approximately 67% nickel and 30% copper, offering superior resistance to seawater, acids, and alkaline environments. This makes it ideal for marine, chemical, and aerospace applications. Monel 400 retains mechanical properties across a wide temperature range, with a melting point of 1,350–1,400°C. It exhibits good ductility, high fatigue strength, and resistance to stress corrosion cracking. Common uses include heat exchangers, pumps, valves, piping systems, and fasteners in harsh conditions. It can be hot- and cold-worked but is difficult to machine due to its toughness. Welding is best performed using Monel-compatible filler metals.

Trade Code

Monel 400 (UNS N04400 / 2.4360) is a nickel-copper alloy known for its excellent corrosion resistance, high strength, and good mechanical properties.

Here are its key features:

1. Corrosion Resistance:

• Excellent resistance to seawater, brackish water, and high-velocity marine environments.
• Highly resistant to acidic and alkaline conditions, including hydrofluoric acid and sulfuric acid.
• Good resistance to stress corrosion cracking and pitting corrosion.

2. Mechanical Properties:

• High strength and toughness, even at subzero temperatures.
• Good ductility and impact resistance.
• Can be hardened only by cold working (not heat-treatable).

3. Thermal Properties:

• Retains mechanical properties at elevated temperatures (~1000°F / 540°C).
• Low thermal expansion compared to austenitic stainless steels.

4. Workability & Fabrication:

• Readily machinable using conventional techniques, but requires slow speeds and rigid tooling due to work hardening.
• Can be welded using gas tungsten arc, gas metal arc, or shielded metal arc welding.
• Good cold and hot forming properties.
