Monel K500 Square Bars
Key Advantages of Monel K500 Square & Hex Bars
Precipitation-Hardened Strength
Aluminum and titanium additions double the tensile strength and triple the yield strength of Monel 400.
Non-Magnetic Stability
Maintains low magnetic permeability down to -101 °C (-150 °F) to prevent sensor interference in directional drilling.
Erosion & Cavitation Resistance
Minimal metal loss under high-velocity saltwater, brackish water, and high-pressure chemical flows.
Sour Gas (H₂S) Immunity
Complies with NACE MR0175 / ISO 15156 for full resistance to sulfide stress corrosion cracking in sour crude environments.
Key Applications of Monel K500 Square & Hex Bars
| Industry | Applications | Operational Benefit |
|---|---|---|
| Oil & Gas Downhole | Drill collars, subsea housings, valve stems | Prevents H₂S sour gas cracking with zero magnetic interference. |
| Marine Propulsion | Pump shafts, impellers, propeller hex bolts | Withstands heavy torsional saltwater fatigue without mechanical shear. |
| Chemical Processing | Valve trim, mixer hex shafts, fasteners | Prevents thread galling and erosion under extreme operational stress. |
| Aerospace & Defense | Structural pins, ordnance actuators, hex fittings | Maintains high tensile strength across temperatures with zero magnetic trace. |

Frequently Asked Questions
Monel K500 incorporates aluminum and titanium to enable precipitation hardening, resulting in approximately double the tensile strength and triple the yield strength of standard Monel 400 while retaining similar corrosion resistance.
Yes. Monel K500 remains non-magnetic at room temperature and retains low magnetic permeability down to sub-zero temperatures, making it suitable for drill collars and sensitive electronic housings.
All deliveries from Aurum Overseas are accompanied by comprehensive EN 10204 3.1 Mill Test Certificates verifying heat chemistry, mechanical properties, hardness levels, and NDT clearance.
