PRODUCT OVERVIEW
About Monel 400 Forged Bar
Monel 400 forged bar arrives in UNS N04400, the solid-solution nickel-copper alloy holding nickel at 63% and above. Flowing seawater, hydrofluoric acid and strong alkali leave this Monel 400 forged bar intact where stainless grades pit or crack.
We supply Monel 400 forged bar to ASTM B164 and ASME SB164 in hot-worked, annealed, stress-relieved and cold-drawn conditions. Your order for this Monel 400 forged bar carries heat-number records and EN 10204 3.1 paperwork for goods-in checks. Besides, diameter, condition and finish on the forged bar are agreed before the heat is booked.
Meanwhile, the chemistry and the design values behind Monel 400 forged bar sit on our Monel 400 material page for cross-reference.
PRODUCT FEATURES
Key Features of Monel 400 Forged Bar
Monel 400 forged bar arrives in UNS N04400, the solid-solution nickel-copper alloy that holds nickel at 63% and above. We provide ASTM B164 and ASME SB164 forged bar in forged, rough-turned and annealed conditions for marine yards, alkylation units and brine plant. Every Monel 400 forged bar order carries heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.
Monel 400
Flowing-Seawater Resistance
For example, this Monel 400 forged bar keeps a clean surface in moving seawater, where 300-series stainless pits within a few seasons.
01
Stagnant-Seawater Caution
However, crevices and silt traps under static conditions attack this Monel 400 forged bar, so design drain-and-flush paths.
02
Hydrofluoric-Acid Capability
Besides, this Monel 400 forged bar handles hydrofluoric acid across all concentrations, a niche few stainless or nickel grades share.
03
Alkali and Salt Duty
In turn, strong caustic and acid-salt streams suit this Monel 400 forged bar, so brine hardware holds tolerance longer.
04
Strength from Cold Work
Cold drawing lifts the yield of this Monel 400 forged bar from the 25 ksi annealed floor toward 85 ksi in light sections.
05
No Age Hardening
Specifically, this Monel 400 forged bar cannot be precipitation hardened, so cold work sets the strength ceiling.
06
Cryogenic Ductility
Moreover, impact strength in this Monel 400 forged bar stays flat through sub-zero and cryogenic plant.
07
Welding Without Post-Weld Anneal
Finally, ERNiCu-7 filler joins this Monel 400 forged bar with no post-weld heat treatment.

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
UNS N04400 carries nickel as its balance and holds copper inside a 28.0% to 34.0% window, so every heat record for this forged bar prints a copper figure rather than a grade name. Besides, that window is what keeps the seawater and acid behaviour of this forged bar repeatable from heat to heat.
For the full element-by-element limit set, open the composition breakdown held on the Monel 400 material page for this forged bar.
Mechanical Properties
The minimum room-temperature values below apply to UNS N04400 bar in the hot-worked, annealed, stress-relieved and cold-worked conditions per ASTM B164. Consequently, condition and section size govern final acceptance of Monel 400 forged bar.
| Condition and Section | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Hot-worked, rounds to 305 mm (12 in.) | ≥80 ksi (552 MPa) | ≥40 ksi (276 MPa) | 30% |
| Hot-worked, annealed, all sizes | ≥70 ksi (480 MPa) | ≥25 ksi (170 MPa) | 35% |
| Cold-worked, stress-relieved, rounds 12.7–88.9 mm (1/2–3-1/2 in.) | ≥87 ksi (600 MPa) | ≥60 ksi (415 MPa) | 20% |
| Cold-worked, as-worked, rounds under 12.7 mm (1/2 in.) | ≥110 ksi (760 MPa) | ≥85 ksi (585 MPa) | 8% |
- Hardness plays no part in ASTM B164 acceptance, so the tensile minimums and the ordered edition decide the release, and the section size narrows which row applies.
Physical Properties
Published references place this forged bar at a density near 8.80 g/cm³ with a melting range of 1300–1350 °C. In addition, the Curie range sits just above ambient, so a forged bar behaves as a weakly magnetic material near room temperature.
Meanwhile, the physical properties table on the Monel 400 material page holds the thermal conductivity, the electrical resistivity and the remaining design values behind this forged bar.
Heat Treatment
Monel 400 forged bar softens by annealing and straightens by a low-temperature relief rather than by aging. In addition, we supply this Monel 400 forged bar in whichever condition your duty calls for.
| Condition | Typical Treatment |
|---|---|
| Annealed | Held between 870 and 980 °C (1600–1800 °F), then cooled |
| Stress Relieved | 300–320 °C (570–610 °F) for about one hour, then air cooled |
| Custom Condition | Heat treatment according to the agreed specification |
Standards
Heavy sections of this forged bar are quoted to ASTM B564 and ISO 9725, because the bar tables of B164 stop short of forged stock. Moreover, AMS 4675 covers forged bar and rings for this forged bar wherever an aerospace document is called up.
| Standard | Product or Application |
|---|---|
| ASTM B564 | Nickel alloy forgings, UNS N04400 listed |
| ISO 9725 | Nickel alloy forgings, international |
| DIN 17754 | Nickel-copper forging stock, Europe |
Finally, the full standards list on the Monel 400 material page adds the European designations, the defence documents and the fastener specifications behind this forged bar.
Dimensions
Dimensions of Monel 400 forged bar follow the manufacturing route, the standard and the order quantity. Therefore, the table below lists typical supply ranges, so please confirm your size in the inquiry.
| Product Form | Typical Supply | Length |
|---|---|---|
| Forged Round Bar | 100–600 mm dia. | Cut to length |
| Forged Square Bar | 100–300 mm | Cut to length |
| Forged Flat Bar | 20–150 mm thick × 50–400 mm wide | Cut to length |
| Rough-Turned Forged Bar | 100–600 mm dia. | Cut to length |
| Forged Block | To drawing | Custom |
| Forging Stock | 100–500 mm sections | Custom |
| Custom Forged Section | To drawing | Custom |
Available sizes of this Monel 400 forged bar depend on the manufacturing route, the standard, the material condition and the order quantity. Please confirm your required forged bar size, section and length in the inquiry.
ASTM B564 lists UNS N04400 forgings, and ISO 9725 or DIN 17754 covers the same grade for European projects. Moreover, AMS 4675 reaches forged bar and rings wherever an aerospace document is called up.
Surface Finishes
Finish decides what the next operation does to this material, whether that is a turning pass, a grinding pass or a welding cell. Specifically, we agree the finish on this Monel 400 forged bar before we release the order.
| Surface Condition | Typical Use |
|---|---|
| Hot-Worked | As-rolled or as-forged surface on this forged bar, for parts that will be machined all over. |
| Rough Turned | A turned surface on this forged bar where the finishing cut is left to your shop. |
| Peeled | A machined skin on this forged bar with uniform diameter for the following turning pass. |
Meanwhile, the surface finishes table on the Monel 400 material page lists the remaining conditions we quote for this forged bar.
