400 Monel Alloy Tube, also known as Monel 400 Tube, is a nickel-copper alloy tube supplied in UNS N04400 for applications requiring reliable corrosion resistance, mechanical strength, and stable performance in demanding environments.
TSM Technology supplies Monel 400 alloy tubes in seamless and welded configurations, with customized outside diameters, wall thicknesses, lengths, surface finishes, heat treatment conditions, and inspection requirements available according to project specifications.
What Is 400 Monel Alloy Tube?
400 Monel Alloy Tube is manufactured from Monel 400, a nickel-copper alloy containing a minimum of approximately 63% nickel and 28–34% copper. The alloy is a solid-solution material and can be strengthened through cold working.
Monel 400 is particularly valued for its resistance to seawater, marine environments, and a range of chemical processing conditions. Its combination of corrosion resistance and mechanical properties makes it suitable for tubes used in marine equipment, chemical processing systems, heat-transfer equipment, pumps, valves, and other industrial applications.
For buyers, the key advantage of Monel 400 tube is its ability to maintain reliable service performance where conventional stainless steels or lower-alloy materials may not provide sufficient corrosion resistance.

For non-standard sizes, provide a drawing or specification so the manufacturing route can be evaluated before quotation.
Monel 400 Tube Manufacturing Process
The manufacturing route depends on tube type, dimensions, and required condition.
Typical Manufacturing Flow
Raw Material → Tube Billet Preparation → Hot Working / Extrusion → Cold Drawing or Cold Rolling → Heat Treatment → Pickling / Surface Treatment → Straightening → Cutting → Dimensional Inspection → NDT → Final Inspection → Marking → Packaging
Cold drawing and cold rolling can be used to achieve tighter dimensional control and specific mechanical properties where required.
Each production order can be controlled according to the applicable material specification and customer requirements.
Monel 400 Tube Corrosion Resistance
One of the main reasons buyers select Monel 400 is its corrosion resistance.
The nickel-copper alloy provides reliable performance in a range of demanding environments, including:

- Chemical processing equipment
- Hydrofluoric acid service under applicable conditions
- Caustic and alkaline environments
- Heat-transfer equipment
- Offshore equipment
Actual corrosion performance depends on temperature, concentration, flow velocity, contaminants, stress conditions, and other service parameters.
For critical chemical service, TSM Technology recommends confirming the operating medium and service conditions before material selection.
