Request Availability →Monel 400 Hex Bar
Monel 400 hex bar to ASTM B164, sized across flats for marine nut blanks, bolting and multi-flat parts.
Seawater and HF Duty Stock
We hold this Monel 400 hex bar for alkylation, marine and brine work where 300-series stainless pits or cracks.
Strength from Cold Work Alone
Specifically, this Monel 400 hex bar cannot be age hardened, so a heavier drawing pass rather than a heat treatment raises its yield.

PRODUCT OVERVIEW
About Monel 400 Hex Bar
Monel 400 hex 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 hex bar intact where stainless grades pit or crack.
We supply Monel 400 hex bar to ASTM B164 and ASME SB164 in hot-worked, annealed, stress-relieved and cold-drawn conditions. Your order for this Monel 400 hex bar carries heat-number records and EN 10204 3.1 paperwork for goods-in checks. Besides, diameter, condition and finish on the hex bar are agreed before the heat is booked.
Meanwhile, the chemistry and the design values behind Monel 400 hex bar sit on our Monel 400 material page for cross-reference.
PRODUCT FEATURES
Key Features of Monel 400 Hex Bar
Monel 400 hex 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 hex bar sized across flats in cold-drawn and hot-worked conditions for marine yards, alkylation units and brine plant. Every Monel 400 hex 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 hex 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 hex bar, so design drain-and-flush paths.
02
Hydrofluoric-Acid Capability
Besides, this Monel 400 hex 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 hex bar, so brine hardware holds tolerance longer.
04
Strength from Cold Work
Cold drawing lifts the yield of this Monel 400 hex bar from the 25 ksi annealed floor toward 85 ksi in light sections.
05
No Age Hardening
Specifically, this Monel 400 hex bar cannot be precipitation hardened, so cold work sets the strength ceiling.
06
Cryogenic Ductility
Moreover, impact strength in this Monel 400 hex bar stays flat through sub-zero and cryogenic plant.
07
Welding Without Post-Weld Anneal
Finally, ERNiCu-7 filler joins this Monel 400 hex 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 hex bar prints a copper figure rather than a grade name. Besides, that window is what keeps the seawater and acid behaviour of this hex 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 hex 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 hex 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 hex 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 hex 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 hex bar.
Heat Treatment
Monel 400 hex bar softens by annealing and straightens by a low-temperature relief rather than by aging. In addition, we supply this Monel 400 hex 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
ASTM B164 is the principal UNS N04400 bar and rod document for this hex bar, published by ASTM International. Moreover, ASME SB164 covers pressure equipment built from this hex bar, and AMS 4675 reaches its bar, forging and ring forms.
| Standard | Product or Application |
|---|---|
| ASTM B164 | Nickel-copper rod, bar and wire, UNS N04400 |
| ASME SB164 | ASME counterpart for pressure equipment |
| AMS 4675 | Bars, forgings and rings of this grade |
Finally, the full standards list on the Monel 400 material page adds the European designations, the defence documents and the fastener specifications behind this hex bar.
Dimensions
Dimensions of Monel 400 hex 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 |
|---|---|---|
| Hex Bar | 10–150 mm A/F | Cut to length or random |

Available sizes of this Monel 400 hex bar depend on the manufacturing route, the standard, the material condition and the order quantity. Please confirm your required hex bar size, section and length in the inquiry.
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 hex bar before we release the order.
| Surface Condition | Typical Use |
|---|---|
| Cold Drawn | Drawn stock giving this hex bar close diameter control and a smooth bright skin. |
| Peeled | A machined skin on this hex bar with uniform diameter for the following turning pass. |
| Rough Turned | A turned surface on this hex bar where the finishing cut is left to your shop. |
Meanwhile, the surface finishes table on the Monel 400 material page lists the remaining conditions we quote for this hex bar.
