Monel 400 Round Bar | Manufacturer, Supplier and Exporter in India
Amardeep Steel is a leading manufacturer, supplier, and exporter of Monel 400 Round Bar available as Monel 400 rod, bar stock, hex bar, and flat bar in a wide range of sizes. Stocked in Mumbai and shipped globally, our ASTM B164 / UNS N04400 material meets the strictest industry standards.
Monel 400, also known as Alloy 400, is a nickel-copper alloy that, when cold worked, develops high hardness, strength, and stiffness. Cold working the ASTM B164 UNS N04400 Bar Stock subjects the alloy to greater mechanical stress, altering its microstructure. This transformation enhances the alloy's strength. As a result, the UNS N04400 Bright Bar gains a higher strength level and a smoother surface texture.
Monel 400 is a little bit magnetic at ambient temperature, and being a nickel-copper alloy, Monel 400 has a high resistance to sea water and steam, even at high temperatures. The 2.4068 Alloy 400 Rod also exhibits resistance to salt solutions as well as caustic substances. Monel 400 can also resist bio-fouling and microbially induced corrosion (MIC) - a significant feature in offshore platform and underwater structures where biological life forms attach to the metal surfaces and increase the rate of corrosion. This has made Monel 400 very popular in such industries as chemical processing, oil and marine engineering.
Cold-worked Monel 400 Round Bar achieves tensile strength up to 760 MPa (110,000 psi) with a hardness of B60 to B95 Rockwell while elongation reduces to approximately 35% compared to 40% in the annealed condition. For structural and engineering applications where strength governs over ductility, this makes Monel 400 bar stock the preferred choice.
Monel 400 Round Bar Price in India
Monel 400 Round Bar price in India varies based on diameter, finish (bright / black / polished), quantity, and delivery destination. As a direct manufacturer, Amardeep Steel eliminates intermediary markups -- pricing starts from mill rates and is adjusted for custom cutting, heat treatment, or export documentation.

What is Monel 400 Bar?
Monel 400 Bar is a solid bar or rod manufactured from Monel 400 -- a nickel-copper alloy (UNS N04400 / 2.4360) containing approximately 63 to 70% nickel and 28 to 34% copper. It is a solid-solution alloy, meaning its strength cannot be increased through heat treatment, only through cold working. This makes Monel 400 bar stock predictable, stable, and reliable in demanding environments including seawater, reducing acids, and high-pressure steam systems. The alloy also exhibits resistance to bio-fouling and microbially induced corrosion (MIC) -- a key advantage in offshore and marine applications.

Types of Monel 400 Round Bar
Monel 400 Round Bar -- Machinability and Fabrication
Monel 400 bar stock machines well in annealed condition. It tends to work-harden during machining, so sharp tooling, slow cutting speeds, and adequate coolant are recommended. The alloy is weldable by TIG, MIG, and SMAW processes using Monel Welding Electrode 190 (MONEL filler 60). Custom-machined components -- pump shafts, valve stems, sleeve bearings, and marine fasteners -- are among the most common finished parts produced from Monel 400 round bar.
Monel 400 Round Bar Application Industries
- Seawater Equipment: Monel 400 bar is machined into pump shafts, valve stems, and propeller shafts for marine hardware -- resistant to both flowing seawater and stagnant brine.
- Pharmaceutical Equipment: Preferred in drug manufacturing where chloride-induced stress corrosion cracking of 316L stainless steel is a risk.
- Specialty Chemicals: Used in reactor components handling hydrofluoric acid and sulphurous acid environments at elevated temperatures.
- Pulp and Paper: Monel 400 rod is specified in digesters and bleach plant equipment where chlorine-containing solutions are present.
- Gas Processing: Applied in sour gas (H2S) environments for valve internals and wellhead components.
- Offshore Oil Drilling: Drill collars, subsea connectors, and tool joints fabricated from Monel 400 bar stock are standard in offshore specifications.
- Heat Exchangers: Monel 400 round bar is turned into tube sheets and baffles for shell-and-tube heat exchangers in desalination and chemical plants.

Frequently Asked Questions (FAQs)
1. What are the available sizes of Monel 400 Round Bar?
Monel 400 Round Bars are available in a variety of sizes, typically ranging from small diameters (3 mm and below) to large diameters (over 12 inches / 800 mm), depending on the supplier and specific requirements.
2. Is Monel 400 Round Bar expensive?
Yes, Monel 400 is generally more expensive than common stainless steels and other alloys due to the high cost of raw materials like nickel and copper. However, its durability and corrosion resistance can justify the cost for many industries.
3. What welding rod is used for Monel 400?
MONEL Welding Electrode 190 is used for shielded-metal-arc welding of MONEL alloys 400, R-405, and K-500. It is also used for surfacing steel. The weld metal is resistant to corrosion by sea water, salts, and reducing acids.
4. What is Monel 400 used for?
Monel 400 is essential in heat exchangers, chemical plant equipment, and boiler feeders. It is ideal in wire or rod form and is excellent for trolling wire due to its resistance to seawater. Monel 400 provides superior quality for mechanical and general engineering applications.
5. How to calculate Monel 400 round bar weight?
To calculate Monel 400 round bar weight: Weight (kg/m) = (Diameter in mm) squared x 0.006908. This uses Monel 400 density of 8.80 g/cm3. Example: a 25 mm diameter bar weighs approximately 25 squared x 0.006908 = 4.32 kg/m. Note: For steel, the multiplier is 0.006165 -- do not use the steel formula for Monel as it will produce an underestimate of approximately 12%.
6. What is the density of Monel 400?
The density of Monel 400 is 8.80 g/cm3 (0.318 lb/in3). Melting point is 1300 to 1350 deg C (2370 to 2460 deg F).
