PRODUCT OVERVIEW
About Monel K-500 Flat Bar
Monel K-500 flat bar arrives in UNS N05500, the age-hardenable nickel-copper alloy that carries aluminium and titanium in its balance. Seawater, brine and de-aerated reducing acids meet this Monel K-500 flat bar at roughly triple the Monel 400 yield floor.
We supply Monel K-500 flat bar to ASTM B865 and ASME SB865 in solution-annealed, age-hardened and cold-drawn conditions. Your order for this Monel K-500 flat bar carries heat-number records and EN 10204 3.1 paperwork for goods-in checks. Besides, the aging cycle, section and finish on the flat bar are agreed before the heat is booked.
Meanwhile, the chemistry and the design values behind Monel K-500 flat bar sit on our Monel K-500 material page for cross-reference.
PRODUCT FEATURES
Key Features of Monel K-500 Flat Bar
Monel K-500 flat bar arrives in UNS N05500, the age-hardenable nickel-copper alloy that carries aluminium and titanium in its balance. We provide ASTM B865 and ASME SB865 flat bar as flat and rectangular sections in hot-worked and age-hardened conditions for marine yards, sour-gas tool shops and chemical plant. Every Monel K-500 flat bar order carries heat-number traceability, EN 10204 3.1 mill test reports and full export documentation.
Monel K-500
Yield Near Triple the 400 Grade
For example, this Monel K-500 flat bar reaches about 100 ksi yield where Monel 400 settles near 25 ksi.
01
Aging Not Cold Work
Specifically, precipitation hardening sets the final properties of this Monel K-500 flat bar, so drawing becomes a pre-treatment.
02
Essentially Non-Magnetic
Besides, permeability in this Monel K-500 flat bar stays near unity, which keeps magnetometers and compasses honest.
03
Hardness to Order
In turn, the aging cycle lands this Monel K-500 flat bar inside the hardness band your purchase order names.
04
Sour-Service Cap
Moreover, we release this Monel K-500 flat bar against the 35 HRC ceiling that NACE MR0175 sets.
05
Wear and Fatigue Life
Hardened surfaces on this Monel K-500 flat bar resist galling and cyclic loading in stems and fasteners.
06
Aged-State SCC Review
However, some media make aged this Monel K-500 flat bar more crack-prone, so we review HF, mercury and sour duty with you.
07
Cryogenic Ductility
Finally, no ductile-to-brittle transition appears, so this Monel K-500 flat bar keeps its toughness down to liquid-hydrogen temperatures.

TECHNICAL INFORMATION
Technical Specifications
Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.
Chemical Composition
UNS N05500 carries the same nickel balance as the 400 grade and adds aluminium at 2.30% to 3.15% together with titanium at 0.35% to 0.85%. Consequently, this flat bar draws its strength from a controlled aging cycle rather than from a drawing pass. Besides, the copper window runs from 27.0% to 33.0%.
For the full element-by-element limit set, open the composition breakdown held on the Monel K-500 material page for this flat bar.
Mechanical Properties
The minimum room-temperature values below apply to UNS N05500 bar in the hot-worked, cold-worked and annealed conditions, all in the age-hardened state, per ASTM B865. Consequently, condition and section size govern final acceptance of Monel K-500 flat bar.
| Condition and Section | Tensile Strength, min. | Yield Strength (0.2%), min. | Elongation, min. |
|---|---|---|---|
| Hot-worked and age-hardened, all sizes | ≥140 ksi (965 MPa) | ≥100 ksi (690 MPa) | 20% |
| Cold-worked and age-hardened, rounds 6.4–25.4 mm (1/4–1 in.) | ≥145 ksi (1000 MPa) | ≥110 ksi (760 MPa) | 15% |
| Cold-worked and age-hardened, rounds 25.4–76.2 mm (1–3 in.) | ≥140 ksi (965 MPa) | ≥100 ksi (690 MPa) | 17% |
| Cold-worked and age-hardened, rounds 76.2–101.6 mm (3–4 in.) | ≥135 ksi (930 MPa) | ≥95 ksi (655 MPa) | 20% |
| Annealed and age-hardened, rounds to 25.4 mm (1 in.) | ≥130 ksi (895 MPa) | ≥90 ksi (620 MPa) | 20% |
| Annealed and age-hardened, rounds over 25.4 mm (1 in.) | ≥130 ksi (895 MPa) | ≥85 ksi (585 MPa) | 20% |
- ASTM B865 accepts the unaged condition on hardness alone with a 185 HB ceiling, and rounds over 108 mm relax to a 17% elongation minimum, so the ordered condition and section decide which row applies.
Physical Properties
Published references place this flat bar at a density near 8.44 g/cm³ with a melting range of 1315–1350 °C. Moreover, the Curie temperature sits near −101 °C, so this flat bar stays essentially non-magnetic at ambient temperature.
Meanwhile, the physical properties table on the Monel K-500 material page holds the thermal conductivity, the electrical resistivity and the remaining design values behind this flat bar.
Heat Treatment
Monel K-500 flat bar gains its strength from solution treatment followed by a controlled aging cycle, so the heat treatment is part of the specification rather than an optional step. In addition, we supply this Monel K-500 flat bar in whichever condition your duty calls for.
| Condition | Typical Treatment |
|---|---|
| Solution Annealed | Held near 980 °C and rapidly quenched to hold aluminium and titanium in solution |
| Aged from Annealed Stock | Held at 580–595 °C (1075–1105 °F) for 8 to 10 hours, then air cooled |
| Aged from Spring Temper | Held at 530–540 °C (985–1005 °F) for 4 to 6 hours, then air cooled |
| Stress Relieved | A low-temperature relief that holds straightness without starting the precipitation |
Standards
ASTM B865 is the principal UNS N05500 bar and rod document for this flat bar, published by ASTM International. Moreover, ASME SB865 covers pressure equipment built from this flat bar, and AMS 4676 reaches its bar, forging and ring forms.
| Standard | Product or Application |
|---|---|
| ASTM B865 | Nickel-copper-aluminium bar, rod and wire, UNS N05500 |
| ASME SB865 | ASME counterpart for pressure equipment |
| AMS 4676 | Bars, forgings and rings of this grade |
Finally, the full standards list on the Monel K-500 material page adds the European designations, the defence documents and the fastener specifications behind this flat bar.

Surface Finishes
Finish decides what the next operation does to this material, whether that is a turning pass, a grinding pass or an aging cycle. Specifically, we fix the finish on this Monel K-500 flat bar before the order is released.
| Surface Condition | Typical Use |
|---|---|
| Hot-Worked | As-rolled or as-forged surface on this flat bar, for parts that will be machined all over. |
| Annealed and Pickled | Annealing followed by acid descaling leaves this flat bar scale-free for fabrication. |
| Polished | Reduced roughness on this flat bar for product-contact and visible components. |
Meanwhile, the surface finishes table on the Monel K-500 material page lists the remaining conditions we quote for this flat bar.
