| Trade designation |
Nimonic grade stated in the product title |
| Important note |
Cross-references do not replace the ordered standard; acceptance depends on chemistry, condition, properties and inspection requirements. |
Typical Chemical Composition
| Nominal composition |
Ni balance; Cr 18.0–21.0%; Fe ≤5.0%; Ti 0.2–0.6%; C 0.08–0.15% |
| Verification |
Final acceptance uses the heat analysis limits in the ordered material specification. |
| Traceability |
Heat number remains linked to the certificate and package marking. |
Typical Physical Properties
| Density |
8.37 g/cm³ |
| Property basis |
Published typical values are guidance values, not guaranteed acceptance criteria. |
| Design use |
Use temperature-dependent design data from the governing specification or an approved engineering source. |
Mechanical Properties and Heat Treatment
| Condition |
Strength and ductility depend on diameter, solution treatment and precipitation-hardening cycle. |
| Acceptance |
Tensile, yield, elongation, reduction of area and hardness follow the ordered specification. |
| Heat treatment |
Temperature uniformity, cooling practice and batch records should be agreed for critical orders. |
| Test sampling |
Test orientation, location and frequency follow the governing standard or approved inspection plan. |
Machining and Fabrication Guidance
| Machining |
Use rigid tooling, positive feeds and suitable coolant; avoid dwell that work-hardens the surface. |
| Forging |
Control working range and reduction; avoid processing below the approved finishing temperature. |
| Welding |
Use qualified procedures appropriate to the alloy, condition and intended service. |
| Post-processing |
Verify dimensions, surface integrity and required NDT after machining or forming. |
Inspection and Quality Documentation
| Material certificate |
EN 10204 3.1 or agreed alternative |
| Identification |
Grade, heat number, diameter, length and package marks |
| Optional testing |
PMI, UT, PT, dimensional report, hardness or third-party inspection by agreement |
| Quotation inputs |
Standard, diameter, length, quantity, condition, tolerance, tests, documentation and destination |
Applications
Typical procurement enquiries include furnace fixtures, thermal-processing hardware, gas-turbine parts and industrial high-temperature components. Suitability must be confirmed for temperature, atmosphere, stress, fatigue and processing route.
Nimonic 75 UNS N06075 Round Bar Packaging
Bars are bundled or placed in export cases according to diameter, surface condition and shipping route. Protection and package markings preserve traceability to the material documents.
