What is UNS N07090?
UNS N07090 is a wrought, precipitation-hardenable nickel-chromium-cobalt superalloy developed for components that must carry load at high temperature. Its strength comes from the gamma-prime phase Ni3(Al,Ti), which precipitates through the austenitic nickel matrix during a controlled ageing treatment. Chromium at 18–21% gives oxidation and hot-corrosion resistance. Cobalt at 15–21% raises the gamma-prime solvus temperature, so the strengthening phase survives hotter than it does in a cobalt-free alloy such as Nimonic 80A.
UNS N07090 is the designation used in the Unified Numbering System for Metals and Alloys. The same material is known commercially as Nimonic 90, as Werkstoff 2.4632 in the German material-number system, as NiCr20Co18Ti in DIN, and is covered by SAE AMS 5829 for bars, forgings and rings. Aerospace users may reference MSRR 7137 or MSRR 7017.
Most enquiries are for parts working between roughly 600 °C and 920 °C under sustained stress. Typical cases are gas turbine discs and blades, hot-working tooling, high-temperature springs and bolting, and rings and shafts in turbomachinery. Below 600 °C a cheaper alloy will normally do the job. Above 950 °C the gamma-prime starts to dissolve and a solid-solution grade such as Haynes 230 or Inconel 617 is the better choice.

Chemical composition of UNS N07090
UNS N07090 contains 18.0–21.0% chromium, 15.0–21.0% cobalt, 2.0–3.0% titanium and 1.0–2.0% aluminium, with nickel as the balance. Carbon is held to 0.13% maximum and iron to 1.5% maximum. The full specification range is given below in weight percent.
| Element | Symbol | Min % | Max % | Role in the alloy |
|---|---|---|---|---|
| Nickel | Ni | Balance | Austenitic matrix | |
| Chromium | Cr | 18.0 | 21.0 | Oxidation and hot-corrosion resistance |
| Cobalt | Co | 15.0 | 21.0 | Raises γ′ solvus, boosts creep strength |

| Lead | Pb | — | 0.0020 | Tramp element |
Tramp elements. Lead, bismuth and sulfur embrittle nickel superalloys at the grain boundaries. Electroslag remelting is what brings them below the specification limits, which is why UNS N07090 for rotating parts is normally ordered ESR rather than as-cast from the arc furnace.
Mechanical properties of UNS N07090 forgings
In the fully heat-treated condition, UNS N07090 forgings typically develop a tensile strength of at least 1170 MPa (170 ksi) and a 0.2% proof strength of at least 750 MPa (109 ksi), with elongation of 20–30%. The values below are room-temperature properties after solution treatment and ageing. Results vary with section size and with whether the specimen is taken tangentially or radially. Heavy sections cool more slowly and usually test a little lower.
| Property | Metric | Imperial | Note |
|---|---|---|---|
| Tensile strength, Rm | ≥ 1170 MPa | ≥ 170 ksi | Typical 1200–1310 MPa |
| 0.2% proof strength, Rp0.2 | ≥ 750 MPa | ≥ 109 ksi | Typical 800–860 MPa |
| Elongation, A | 20–30 % | 20–30 % | On 4D or 5D gauge |
| Reduction of area, Z | 20–30 % | 20–30 % | Section dependent |
| Hardness | 300–360 HB | 32–39 HRC | After full ageing |
| Young's modulus, E | ≈ 215 GPa | ≈ 31 × 10⁶ psi | At 20 °C |
| Modulus of rigidity, G | ≈ 83 GPa | ≈ 12 × 10⁶ psi | At 20 °C |
| Impact, Charpy V | ≥ 25 J | ≥ 18 ft·lb | When specified |
Elevated-temperature behaviour
UNS N07090 holds a high proportion of its room-temperature strength to about 700 °C, then falls away as the gamma-prime coarsens. Its practical creep and stress-rupture limit is around 920 °C. Young's modulus falls from roughly 215 GPa at 20 °C to about 165 GPa at 800 °C. Use the hot figure for interference-fit and finite-element work on turbine discs. If the design point sits above 920 °C under load, ask us about Haynes 230 or Inconel 617 instead.

Heat treatment and melting route
Standard heat treatment
The standard heat treatment for UNS N07090 is 8 hours at 1080 °C (1975 °F) followed by air cooling, then 16 hours at 700 °C (1290 °F) followed by air cooling. The first stage dissolves the gamma-prime and homogenises the structure; the second precipitates it in a fine, uniformly distributed form. Air cooling instead of quenching keeps residual stress low in heavy sections. That matters on large rings and discs that go on to tight-tolerance finish machining.
| Stage | Temperature | Time | Cooling | Purpose |
|---|---|---|---|---|
| Hot working | 1050–1200 °C | — | Air | Forging, ring rolling, upsetting |
| Solution treatment | 1080 °C (1975 °F) | 8 h | Air cool | Dissolve γ′, homogenise |
| Precipitation ageing | 700 °C (1290 °F) | 16 h | Air cool | Precipitate fine γ′ for full strength |
Melting route used for UNS N07090 at this works
Jiangyin Jiangnan Metal melts UNS N07090 by electric arc furnace, followed by AOD or VOD refining, followed by electroslag remelting (EAF + VOD + ESR). ESR matters most for rotating parts. It lowers sulfur and oxide inclusion content, breaks up macro-segregation and gives a directionally solidified ingot with a sound centre. Without it, heavy rings and discs are prone to centreline defects. Vacuum induction melting plus vacuum arc remelting (VIM + VAR) can be arranged where an aerospace specification calls for it. Say so on the enquiry.

Machining, welding and forming notes
Machining
UNS N07090 work hardens fast and conducts heat poorly, so the heat concentrates at the cutting edge. Rough machining is easiest in the solution-treated condition, before ageing. Use rigid setups, positive rake carbide or ceramic inserts, flood coolant, and speeds well below what you would run on stainless. Keep the feed constant and under the work-hardened surface layer. Do not let the tool dwell; an interrupted feed glazes the surface and the next edge fails early.
Welding
The alloy welds by GTAW and electron beam, but the titanium and aluminium leave it open to strain-age cracking in the heat-affected zone. Weld in the solution-treated condition where you can, keep heat input low, then re-solution treat and age. Talk to us before committing to a welded structural joint in aged material.
Hot forming
Hot work between 1050 °C and 1200 °C. The window is narrow. Below 1050 °C the alloy is stiff and cracks; above 1200 °C there is a risk of grain growth and incipient melting. More reheats are needed to finish the same shape, which is a large part of why UNS N07090 forgings cost more than cobalt-free nickel-chromium grades.

Buying from the works. Much of the nickel superalloy forging sold out of China is resold by traders who never see the ingot. We forge in house, so the melt route, reheat schedule, reduction ratio and heat treatment are controlled in one place and reported on one certificate. If an ultrasonic indication or a tensile result needs explaining, you are talking to the people who made the part.

Frequently asked questions about UNS N07090
What is UNS N07090?
UNS N07090 is a precipitation-hardenable nickel-chromium-cobalt superalloy strengthened by additions of titanium and aluminium, which form gamma-prime precipitates during ageing. It contains roughly 18–21% chromium, 15–21% cobalt, 2–3% titanium and 1–2% aluminium, with nickel as the balance. It is commercially known as Nimonic 90 and carries material number 2.4632. Jiangyin Jiangnan Metal Co., Ltd. supplies UNS N07090 as open-die forgings including seamless rolled rings, discs, shafts, flanges and bars.
Is UNS N07090 the same as Nimonic 90?
Yes. UNS N07090 is the Unified Numbering System designation for the alloy sold commercially as Nimonic 90. The same material is also designated 2.4632 (and 2.4969) in the German Werkstoff system, NiCr20Co18Ti in DIN, AMS 5829 in the SAE aerospace system, and BS HR 501, HR 502 and HR 503 in British Standards. All of these designations refer to the same nickel-chromium-cobalt superalloy.
What is the maximum service temperature of UNS N07090?
UNS N07090 retains useful stress-rupture strength and creep resistance up to about 920 °C (1690 °F). For oxidation resistance without significant load it can be used higher, but the practical design limit for stressed rotating and pressure-carrying parts is around 920 °C. Above roughly 950 °C the gamma-prime strengthening phase begins to dissolve and the alloy loses much of its high-temperature strength.
What are the mechanical properties of UNS N07090 forgings?
In the fully heat-treated condition (solution treated 8 hours at 1080 °C, air cooled, then aged 16 hours at 700 °C, air cooled), UNS N07090 forgings typically show a tensile strength of at least 1170 MPa (170 ksi), a 0.2% proof strength of at least 750 MPa (109 ksi), elongation around 20–30% and hardness of 300–360 HB. Actual values depend on section size and on the tangential or radial orientation of the test specimen.
What heat treatment is used for UNS N07090?
The standard heat treatment is a solution treatment of 8 hours at 1080 °C (1975 °F) followed by air cooling, then a precipitation ageing treatment of 16 hours at 700 °C (1290 °F) followed by air cooling. This two-stage cycle precipitates the gamma-prime Ni3(Al,Ti) phase that gives the alloy its high-temperature strength. Forgings are hot worked between 1050 °C and 1200 °C before heat treatment.
Which forged shapes can be made in UNS N07090?
Jiangyin Jiangnan Metal Co., Ltd. produces UNS N07090 as seamless rolled rings, forged discs, shafts, flanges, round bars, sleeves, bushings, tube sheets, forged pipes and tubes, gear blanks, spindles, valve bodies and stems, nozzles and custom near-net shapes made to drawing. Rolled rings are produced to approximately 4,000 mm outside diameter and single pieces up to about 10,000 kg.
What is the difference between UNS N07090 and Nimonic 80A?
Nimonic 80A (UNS N07080) is a nickel–chromium alloy with essentially no deliberate cobalt addition, while UNS N07090 (Nimonic 90) adds 15–21% cobalt. The cobalt raises the solvus temperature of the gamma-prime phase and improves creep and stress-rupture strength at high temperature, so N07090 is the stronger of the two above about 700 °C. Nimonic 80A is generally cheaper and is common in exhaust valves and fasteners; N07090 is preferred for turbine discs, blades and hot rotating parts. See also Nimonic 80A forgings.
Which standards cover UNS N07090 forgings?
UNS N07090 forgings and forging stock are commonly ordered to SAE AMS 5829, to BS HR 501, HR 502 and HR 503, and within the ASTM B637 family of precipitation-hardening nickel alloy bars, forgings and forging stock. Aerospace users may also reference MSRR 7137, MSRR 7017 and AECMA prEN 2295 or 2296. Material certificates are issued to EN 10204 type 3.1, or type 3.2 with third-party inspection.
How is UNS N07090 melted and tested?
Jiangyin Jiangnan Metal melts UNS N07090 by electric arc furnace followed by AOD or VOD refining and electroslag remelting (EAF + VOD + ESR), which lowers sulfur and non-metallic inclusion content and improves ingot soundness for forging. Finished forgings are ultrasonically inspected to EN 10228-3, SEP 1921 or ASTM A388 as specified on the order, with chemical analysis, tensile testing, hardness and grain size reported on the certificate.
Who supplies UNS N07090 forgings from China?
Jiangyin Jiangnan Metal Co., Ltd. is an open-die forging factory at No.1 Chengxiqiao Road, Zhouzhuang Town, Jiangyin City, Jiangsu Province, China that manufactures UNS N07090 (Nimonic 90) forgings to customer drawing. Enquiries can be sent to sales@steelforgepieces.com or by phone to +86 189 2135 9659. Quotations are normally returned within 24 hours of receiving a drawing or dimensions.
What is the lead time for UNS N07090 forgings?
Typical lead time is 25 to 45 days from order confirmation, depending on section size, whether the ingot is in stock, and how much machining and heat treatment is required. Simple rolled rings and discs from stock billet sit at the shorter end of that range; large heavy-section forgings that need a dedicated ESR ingot take longer.
