| Important note |
Cross-references do not replace the ordered standard; acceptance depends on chemistry, condition, properties and inspection requirements. |
Typical Chemical Composition
| Nominal composition |
Nickel-chromium-cobalt alloy with molybdenum, aluminium and titanium; exact limits must be verified against the ordered specification |
| 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 |
approximately 8.0 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 gas-turbine components and other high-stress elevated-temperature machined parts. Suitability must be confirmed for temperature, atmosphere, stress, fatigue and processing route.
