Monel K-500 Round Bar

Monel K-500 round bar to ASTM B865 for aged marine shafts, sour-gas tool bodies and non-magnetic instrument parts.

Grade: Monel K-500 UNS N05500 Werkstoff Nr. 2.4375
Aging Sets the Strength

Aluminium and titanium in this Monel K-500 round bar precipitate during the aging cycle, so yield lands near three times the Monel 400 figure.

Non-Magnetic by Nature

Moreover, permeability in this Monel K-500 round bar stays near unity, which keeps survey and instrument parts reading clean.

Sour Service Under a Cap

Furthermore, we hold this Monel K-500 round bar to the 35 HRC ceiling that NACE MR0175 sets for H2S-bearing duty.

PRODUCT OVERVIEW

About Monel K-500 Round Bar

Monel K-500 round 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 round bar at roughly triple the Monel 400 yield floor.

We supply Monel K-500 round bar to ASTM B865 and ASME SB865 in solution-annealed, age-hardened and cold-drawn conditions. Your order for this Monel K-500 round bar carries heat-number records and EN 10204 3.1 paperwork for goods-in checks. Besides, the aging cycle, section and finish on the round bar are agreed before the heat is booked.

Meanwhile, the chemistry and the design values behind Monel K-500 round bar sit on our Monel K-500 material page for cross-reference.

Yield Near Triple the 400 Grade

For example, this Monel K-500 round 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 round bar, so drawing becomes a pre-treatment.

02

Essentially Non-Magnetic

Besides, permeability in this Monel K-500 round bar stays near unity, which keeps magnetometers and compasses honest.

03

Hardness to Order

In turn, the aging cycle lands this Monel K-500 round bar inside the hardness band your purchase order names.

04

Sour-Service Cap

Moreover, we release this Monel K-500 round bar against the 35 HRC ceiling that NACE MR0175 sets.

05

Wear and Fatigue Life

Hardened surfaces on this Monel K-500 round bar resist galling and cyclic loading in stems and fasteners.

06

Aged-State SCC Review

However, some media make aged this Monel K-500 round 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 round bar keeps its toughness down to liquid-hydrogen temperatures.

08

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 round 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 round 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 round 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 round 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 round 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 round bar.

Heat Treatment

Monel K-500 round 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 round 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 round bar, published by ASTM International. Moreover, ASME SB865 covers pressure equipment built from this round bar, and AMS 4676 reaches its bar, forging and ring forms.
