Key Advantages of UNS N05500 Round Bars
High Mechanical Yield Strength
Age-hardened with aluminum (2.3–3.15%) and titanium (0.35–0.85%) to deliver a massive 790 MPa minimum yield strength for extreme mechanical loads.
NACE MR0175 Sour Gas Certified
Impervious to sulfide stress cracking (SSC) and hydrogen embrittlement in harsh, downhole sour oilfield environments.
Non-Magnetic Performance
Retains ultra-low magnetic permeability from ambient down to cryogenic temperatures, making it essential for non-magnetic drill collars and sensitive electronics.
Cavitation & Wear Resistance
Enhanced surface hardness protects pump impellers, propeller shafts, and valve stems against high-velocity seawater erosion and cavitation.
Key Applications of Monel K500 Round Bars
| Industry Sector | Typical Components | Operating Conditions |
|---|---|---|
| Oil & Gas Drilling | Non-magnetic drill collars, downhole tool shafts, wellhead valves, and rotary stems | Deep sour gas wells (H₂S), high-pressure brines, and heavy torsional loads |
| Marine & Naval Defense | Propeller shafts, impellers, valve stems, pump shafts, and marine fasteners | High-velocity seawater currents, cavitation environments, and heavy dynamic loading |
| Chemical Processing | Mixers, doctor blades, scrapers, and slurry pump shafts | Corrosive process streams, abrasive mineral slurries, and continuous shear forces |
| Offshore Subsea Engineering | Subsea riser bolts, hydraulic line shafts, and mooring hardware | High hydrostatic pressures, splash zone exposure, and cyclical wave stress |
| Aerospace & Defense | Rocket engine pump shafts, instrument components, and non-magnetic housings | Extremes in thermal loading, high shaft speeds, and strict non-magnetic limits |
Quality Testing & Inspection
Every batch of ASTM A479 Monel K500 Round Bars supplied by Aurum Overseas undergoes rigorous testing:
- Positive Material Identification (PMI): High-precision XRF testing confirms chemical compliance, ensuring proper ratios of nickel (63% min), copper, aluminum, and titanium.
- Mechanical Strength Verification: Tensile testing verifies that age-hardened stock achieves a minimum 790 MPa yield strength and 1100 MPa ultimate tensile strength.
- Hardness Testing: Brinell and Rockwell C scale measurements confirm uniform age-hardening through the core of large-diameter forged bars.
- Ultrasonic Volumetric Testing: Ultrasonic examination per ASTM A388 detects subsurface inclusions, micro-cracks, or forging discontinuities.

Frequently Asked Questions
Monel K500 contains added aluminum and titanium, allowing age-hardening heat treatment. This triples the yield strength and doubles the tensile strength compared to Monel 400 while keeping the same excellent corrosion resistance.
Yes. Monel K500 remains non-magnetic even after age-hardening and down to cryogenic temperatures, making it ideal for non-magnetic drill collars and sensor housings.
We stock sizes from 3 mm to 500 mm in centerless ground bright finishes and heavy hot-forged conditions, available in standard 3-meter, 6-meter, or custom cut-to-length options.
Yes. Every order ships with complete EN 10204 3.1 Mill Test Certificates verifying heat chemistry, mechanical properties, hardness, and heat treatment compliance.
