What is Monel 400?

Monel 400, also known by its UNS designation N04400, is a solid-solution alloy composed primarily of nickel and copper. Developed for exceptional corrosion resistance and durability, Monel 400 is especially effective in marine environments and chemical processing systems. This alloy retains strength across a wide temperature range, offering dependable performance even under extreme conditions.

Key Benefits of Monel 400 Round Bar

Monel 400 stands out among nickel-based alloys for its versatility and resilience. Some of the primary advantages that make it a top choice for industrial-grade applications include:

  • Exceptional Corrosion Resistance – Performs reliably in saltwater, acids (including hydrofluoric and sulfuric), and alkalis.
  • High Strength and Toughness – Maintains mechanical integrity from cryogenic temperatures to above 1,000°F.
  • Good Weldability – Compatible with standard arc and gas welding techniques.
  • Stress-Corrosion Cracking Resistance – Superior resistance compared to many stainless steels.
  • Magnetic Properties – Non-magnetic in annealed condition, slightly magnetic in cold-worked states.

Common Industrial Applications

The unique chemical and mechanical properties of UNS N04400 rods make them ideal for use in a wide range of high-risk, high-demand environments. Here are some of the most common industry applications:

Marine Engineering

Monel 400 is a go-to material in marine environments due to its superior resistance to seawater and brine. It is often used for:

  • Propeller and pump shafts
  • Valve components exposed to saltwater
  • Heat exchanger tubing and seawater intakes

Chemical Processing

Thanks to its compatibility with a broad range of corrosive substances, Monel 400 is widely employed in chemical plants. Typical uses include:

  • Storage tanks for hydrofluoric and sulfuric acids
  • Reactor vessels and agitators
  • Caustic handling equipment and piping

Oil and Gas

This alloy delivers both corrosion and pressure resistance, making it suitable for upstream and downstream operations. It’s frequently found in:

  • Downhole and completion tools
  • Offshore platform fittings and flanges
  • Sour gas service environments

Aerospace

In aerospace manufacturing, weight, corrosion resistance, and mechanical stability are essential. Monel 400 is used for:

  • Hydraulic tubing and fuel lines
  • Structural fasteners and brackets
  • Exhaust and combustion components

Chemical Composition of Monel 400 (UNS N04400)

This alloy is primarily a blend of nickel and copper, with minor elements that enhance its corrosion resistance and mechanical strength. Its typical composition includes:

  • Nickel (Ni): 63.0% min
  • Copper (Cu): 28.0–34.0%
  • Iron (Fe): Up to 2.5%
  • Manganese (Mn): Up to 2.0%
  • Silicon (Si): Up to 0.5%
  • Carbon (C): Up to 0.30%
  • Sulfur (S): Max 0.024%
  • Phosphorus (P): Max 0.030%
  • Lead (Pb): Max 0.005%
