Monel K-500
Yield Near Triple the 400 Grade
For example, this Monel K-500 hex 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 hex bar, so drawing becomes a pre-treatment.
02
Essentially Non-Magnetic
Besides, permeability in this Monel K-500 hex bar stays near unity, which keeps magnetometers and compasses honest.
03
Hardness to Order
In turn, the aging cycle lands this Monel K-500 hex bar inside the hardness band your purchase order names.
04
Sour-Service Cap
Moreover, we release this Monel K-500 hex bar against the 35 HRC ceiling that NACE MR0175 sets.
05
Wear and Fatigue Life
Hardened surfaces on this Monel K-500 hex bar resist galling and cyclic loading in stems and fasteners.
06
Aged-State SCC Review
However, some media make aged this Monel K-500 hex 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 hex 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 hex 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 hex 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 hex 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 hex 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 hex 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 hex bar.
Heat Treatment
Monel K-500 hex 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 hex 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 hex bar, published by ASTM International. Moreover, ASME SB865 covers pressure equipment built from this hex 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 hex bar.
