Equivalent Designations
| UNS |
N07263 |
| Werkstoff |
2.4650 |
| Trade designation |
Nimonic grade stated in the product title |
| Important note |
Designations are cross-references only; compliance is determined by the ordered standard, chemistry, mechanical properties and condition. |
Typical Chemical Composition
| Nominal composition |
Ni balance; Cr 19.0–21.0%; Co 19.0–21.0%; Mo 5.6–6.1%; Ti 1.9–2.4%; Al ≤0.6% |
| Verification |
Final acceptance shall use the heat analysis and limits in the ordered material specification. |
| Traceability |
Heat number is linked to the material certificate and package identification. |
Typical Physical Properties
| Density |
8.36 g/cm³ |
| Property basis |
Published typical values are guidance values and are not guaranteed acceptance criteria. |
| Design use |
Engineering design should use temperature-dependent data from the applicable specification or approved material source. |
Mechanical Properties and Heat Treatment
| Condition |
Properties depend on product thickness, solution treatment and any precipitation-hardening cycle. |
| Acceptance |
Tensile, yield, elongation and hardness requirements follow the purchase specification. |
| Heat treatment |
Furnace control, temperature uniformity, cooling practice and batch records should be agreed where critical. |
| Sampling |
Test direction, location and frequency follow the governing standard or approved inspection plan. |
Fabrication Guidance
| Cold forming |
Allow for work hardening, bend radius and intermediate annealing when required. |
| Machining |
Use rigid tooling, positive feeds and suitable coolant; avoid dwell that can work-harden the surface. |
| Welding |
Keep joint surfaces clean and use qualified procedures appropriate to the alloy and service. |
| Post-fabrication |
Remove contamination and verify dimensions, surface and required NDT after processing. |
Inspection and Quality Documentation
| Material certificate |
EN 10204 3.1 or agreed alternative |
| Identification |
Grade, heat number, size and package marks |
| Optional testing |
PMI, UT, PT, dimensional report, hardness or third-party inspection by agreement |
| Quotation inputs |
Standard, size, quantity, condition, tolerance, testing, documentation and delivery destination |
Applications
Typical procurement enquiries include combustion chambers, transition ducts, turbine casing components and hot-section sheet fabrications. Application suitability must be confirmed by the purchaser’s engineer for temperature, atmosphere, stress and fabrication route.
Nimonic 263 UNS N07263 Sheet and Plate Packaging
Sheets and plates are separated and protected as required, secured on pallets or in export cases, and marked so package identification remains linked to the material documentation.
Procurement Confirmation
| Please provide |
Grade and standard; dimensions; quantity; condition; tolerance and surface; test and certificate requirements; destination and requested delivery date |
| Quotation review |
Availability, production route, technical compliance, packing and lead time are confirmed before acceptance. |
