Monel® 400 is a ductile Nickel-Copper alloy with resistance to a wide variety of corrosive conditions. Monel 400’s low corrosion rate in flowing seawater makes it well suited for the oil & gas industry, and other marine engineering applications.

Monel® 400 is a ductile Nickel-Copper alloy with resistance to a wide variety of corrosive conditions. This alloy is most frequently applied in a range of environments going from mildly oxidizing through neutral and to moderately reducing conditions. Additional application area of this material is in marine environments and other non-oxidizing chloride solutions. Like with commercially pure Nickel, Monel® 400 is low in strength in the annealed condition, for this reason a variety of tempers are used to achieve higher strength levels.

Monel 400 is a nickel-copper alloy with high strength and excellent corrosion resistance in a range of media including sea water, hydrofluoric acid, sulfuric acid, and alkalies. While, Monel K-500 is a precipitation-hardenable nickel-copper alloy that combines the corrosion resistance of MONEL 400 with greater strength and hardness.

Alloy 400 seamless pipes and tubing’s are available in both OD and NB sizes. In addition to standard sizes, which are available in stock, our specialty is to manufacture and supply custom size Alloy 400 cold drawn seamless tubing’s from our factory.

Dinesh Tube India offers Nickel Alloy 400 Tubing in random lengths of up to 6 meters long or cut to a specific length as ordered. Monel pipes and tubes are largely used for piping in Process Vessels, Heat Exchangers, and Storage Tanks.

Monel 400 Seamless Pipes and Tubes: ASTM B165, ASTM B163, ASME SB165, ASME SB163

We can offer ex-stock supply of most of the standard size Monel Alloy 400 alloy pipes and Monel Alloy 400 tubes. Custom size (thickness x OD) Monel Alloy 400 pipes can be offered with short delivery times to meet the most demanding requirements of our customers.

Monel® 400 can be cold rolled to various tempers. Contact Dinesh Tube India for additional information.



Refer to NACE (National Associate of Corrosion Engineers) for recommendations.


#1 – Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D – Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
#2B – Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA- Bright annealed cold rolled and bright annealed
#CBA- Course bright annealed cold rolled matte finish and bright anneal
#2 – Cold Rolled
#2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished – Various grit finish for specific polish finished requirements.


XC – Extra Clean Bright Annealed or Bright Annealed and Cold Rolled Grease – Ultra bright finish (for decorative applications)
Soap – Soap coating on tempered wire to act as lubricant.


Monel® 400 is non hardenable by heat treatment.
