PRODUCT OVERVIEW
About Monel 400 Centreless-Ground Rod
Monel 400 centreless-ground rod 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 centreless-ground rod intact where stainless grades pit or crack.
We supply Monel 400 centreless-ground rod to ASTM B164 and ASME SB164 in hot-worked, annealed, stress-relieved and cold-drawn conditions. Your order for this Monel 400 centreless-ground rod carries heat-number records and EN 10204 3.1 paperwork for goods-in checks. Besides, diameter, condition and finish on the centreless-ground rod are agreed before the heat is booked.
Meanwhile, the chemistry and the design values behind Monel 400 centreless-ground rod sit on our Monel 400 material page for cross-reference.
PRODUCT FEATURES
Key Features of Monel 400 Centreless-Ground Rod
Monel 400 centreless-ground rod arrives in UNS N04400, the solid-solution nickel-copper alloy that holds nickel at 63% and above. We provide ASTM B164 and ASME SB164 centreless-ground rod ground to a tight diameter and straightness band for marine yards, alkylation units and brine plant. Every Monel 400 centreless-ground rod 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 centreless-ground rod 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 centreless-ground rod, so design drain-and-flush paths.
02
Hydrofluoric-Acid Capability
Besides, this Monel 400 centreless-ground rod 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 centreless-ground rod, so brine hardware holds tolerance longer.
04
Strength from Cold Work
Cold drawing lifts the yield of this Monel 400 centreless-ground rod from the 25 ksi annealed floor toward 85 ksi in light sections.
05
No Age Hardening
Specifically, this Monel 400 centreless-ground rod cannot be precipitation hardened, so cold work sets the strength ceiling.
06
Cryogenic Ductility
Moreover, impact strength in this Monel 400 centreless-ground rod stays flat through sub-zero and cryogenic plant.
07
Welding Without Post-Weld Anneal
Finally, ERNiCu-7 filler joins this Monel 400 centreless-ground rod with no post-weld heat treatment.
08

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 centreless-ground rod prints a copper figure rather than a grade name. Besides, that window is what keeps the seawater and acid behaviour of this centreless-ground rod 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 centreless-ground rod.
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 centreless-ground rod.
| 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 centreless-ground rod 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 centreless-ground rod 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 centreless-ground rod.
Heat Treatment
Monel 400 centreless-ground rod softens by annealing and straightens by a low-temperature relief rather than by aging. In addition, we supply this Monel 400 centreless-ground rod 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 centreless-ground rod, published by ASTM International. Moreover, ASME SB164 covers pressure equipment built from this centreless-ground rod, 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 centreless-ground rod.

Available sizes of this Monel 400 centreless-ground rod depend on the manufacturing route, the standard, the material condition and the order quantity. Please confirm your required centreless-ground rod 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 centreless-ground rod before we release the order.
| Surface Condition | Typical Use |
|---|---|
| Hot-Worked | As-rolled or as-forged surface on this centreless-ground rod, for parts that will be machined all over. |
| Centreless Ground | Ground diameter and straightness on this centreless-ground rod for shafts and spindles. |
| Polished | Reduced roughness on this centreless-ground rod for product-contact and visible components. |
