Monel 400 UNS N04400 Forged Round Bar with Excellent Seawater Corrosion Resistance for Marine and Chemical Service Environments

Monel 400 UNS N04400 Forged Round Bar

Monel 400 forged round bar is a high-performance nickel-copper solid-solution strengthened alloy with excellent corrosion resistance, particularly in seawater and chloride environments. It offers stable mechanical properties and is widely used in marine, offshore, and chemical industries.

Key Features

• Excellent resistance to seawater and salt spray corrosion.
• Good resistance to stress corrosion cracking (SCC) .
• Retains toughness at low temperatures.
• Non-magnetic properties.
• Suitable for forged shafts, rings, and structural components.

Typical Applications

• Marine: Desalination units, seawater pumps, valves and fittings.
• Fluorochemical: HF reactors, desulfurization parts.
• Alkali industry: Caustic evaporators, lye pumps.
• Oil & gas: Downhole corrosion-resistant piping, desulfurization gear.
• Cryogenic equipment: LNG sleeves, low-temp pumps.
• Miscellaneous: Aviation fuel lines, distillation and corrosion-resistant elastic parts.
