Production routes	Hot rolled, forged, peeled, turned and precision ground
Cutting	Saw-cut blanks and fixed lengths
Machining allowance	Added only when specified for subsequent finishing
Straightness / tolerance	Commercial or precision tolerances agreed before production
Ends	Plain, chamfered or customer-specified end preparation

Equivalent Designations

UNS	N07086
Werkstoff	2.4959
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 24.0–27.0%; Mo 9.0–11.0%; Ti 1.8–2.7%; Al ≤0.5%
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	8.10 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 combustion hardware, furnace components, exhaust-system parts and machined high-temperature components. Suitability must be confirmed for temperature, atmosphere, stress, fatigue and processing route.
