Monel 400 Welded Pipe Tube (UNS N04400 / W.Nr. 2.4360)
High-strength corrosion-resistant alloy Pipe Tube for Marine and Chemical Processing
As a leading Chinese Monel pipe supplier, SEATHER manufactures high-quality Monel 400 welded pipe and tube in a wide range of sizes to meet diverse industrial requirements.
MONEL® nickel–copper alloy 400 (UNS N04400 / W.Nr. 2.4360) is a solid-solution alloy that can only be hardened by cold working. It offers high strength, excellent toughness across a broad temperature range, and outstanding resistance to many corrosive environments, especially seawater and chemical media.
Monel 400 welded pipe & tube is produced by forming and welding high-quality Monel 400 strip or plate. Because welded products rely heavily on the stability of raw materials, SEATHER sources coils and plates exclusively from reputable large-scale mills to ensure consistent chemical composition and mechanical properties. We also employ advanced slitting and precision welding technology to guarantee weld integrity and dimensional accuracy for every tube we manufacture.
For applications requiring superior corrosion resistance or improved mechanical performance, we offer solution-annealed Monel 400 welded pipe and tube, processed with our continuous online solid solution equipment to achieve uniform microstructure and optimal performance.
If you need reliable Monel 400 welded pipes or tubes with excellent corrosion resistance and stable weld quality, SEATHER is your trusted supplier.

More Information About Monel 400 Welded Pipe Tube (UNS N04400)
When you choose to buy Monel 400 welded Pipe Tube (UNS N04400), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Monel 400 Welded Pipe Tube (UNS N04400)
Monel 400 PREN: 40.0
The pitting resistance equivalency number uses the alloy’s chemical makeup to guess its power against pitting corrosion. You check how much chromium, molybdenum, tungsten, and nitrogen are in the alloy. These elements help keep the steel safe. The most used formula is:
PREN = CR% + 3.3 x (MO% + 0.5 x W%) + 16 x N%How to Purchase Monel 400 Welded Pipe Tube (UNS N04400)
