Machining Recommendations
Monel K500 machines similarly to austenitic stainless steels. Recommended cutting speed: 15-25 m/min for turning, 10-20 m/min for drilling. Use carbide or HSS tools with positive rake angles. Water-soluble coolants prevent work hardening. Avoid excessive heat buildup during machining of age-hardened material.

| Density | 8.44 g/cm³ |
| Melting Point | 1350°C |
| Tensile Strength | 1100 MPa |
| Yield Strength | 790 MPa |
| Elongation | 20% |
Heat Treatment & Age Hardening
Monel K500 achieves maximum strength through precipitation hardening at 593°C (1100°F) for 16 hours, followed by air cooling. This process increases tensile strength from 790 MPa (annealed) to 1100 MPa (age-hardened) while maintaining ductility. We supply bars in both conditions and can provide custom heat treatment per your specifications.

FAQs About Monel K500 Round Bar
Monel K500 round bars are used in marine applications (pump shafts, propeller shafts), chemical processing equipment, oil & gas drilling components, and aerospace fasteners where high strength and corrosion resistance are critical.
Monel K500 is precipitation-hardenable with 3x the tensile strength of Monel 400 (1100 MPa vs 550 MPa). K500 contains aluminum and titanium for age-hardening, while maintaining similar corrosion resistance.
No, Monel K500 is non-magnetic in both annealed and age-hardened conditions, making it suitable for applications requiring non-magnetic properties.
We stock Monel K500 round bars from 3mm to 800mm diameter in various conditions (cold drawn, hot rolled, annealed, precipitation hardened) with custom lengths up to 6 meters.
Standard sizes from ready stock ship within 3-5 business days. Custom specifications require 2-3 weeks depending on size and finish requirements.
All Monel K500 bars include material test certificates (MTC) per EN 10204 3.1, chemical analysis reports, mechanical property test results, and heat treatment certificates where applicable.
Yes, Monel K500 can be welded using TIG, MIG, or shielded metal arc welding. Filler metal should be ERNiCu-7 or ENiCu-7. Pre-weld heat treatment may be required for age-hardened material.
