What UNS N06003 is, and when to specify it
UNS N06003 is the UNS designation for the 80/20 nickel-chromium alloy that furnace builders have used for more than a century. Nobody buys it for room-temperature strength. It gets specified because the oxide film survives repeated heating and cooling, and because the electrical resistance barely drifts as the part heats up.
The alloy is nickel with about a fifth of chromium dissolved in it and almost no iron. In service the chromium forms a thin Cr₂O₃ scale that adheres unusually well, so the film does not spall when the part is switched on and off or cycled through a wide temperature swing. That adhesion is the reason 80/20 outlasts iron-chromium-aluminium alloys in cyclic duty even though FeCrAl grades tolerate a higher peak temperature. Because the alloy carries no significant iron, it also avoids the iron-oxide growth that shortens the life of the cheaper 60/15 and 37/18 nickel-chromium grades.
Specify UNS N06003 when the part lives inside a furnace, an enamelling oven, a heat-treatment retort or a heating assembly, and the atmosphere is air, nitrogen, ammonia or another clean oxidising or neutral gas. Specify something else when the part is pressure retaining, when sulfur is present, or when the design is governed by creep-rupture allowables. Alloy 80/20 has no ASME Boiler and Pressure Vessel Code stress table, so it is not the grade for a coded pressure part. Incoloy 800H, Inconel 600 and Inconel 617 normally are.
UNS N06003 is a solid-solution alloy. It has no age-hardening reaction, so there is no solution-and-age cycle to specify and no way to raise its strength by heat treatment. Room-temperature strength comes from the annealed structure and, in wire and strip, from cold work. In forgings, the property that matters is a uniform recrystallised grain after annealing.
Forging behaviour
Alloy 80/20 forges well but has a narrower hot-working window than a stainless steel. Heating is done to 1150–1180 °C in a clean, low-sulfur furnace atmosphere; forging is finished above about 950 °C, because working the alloy cold enough to leave heavy residual strain and then annealing at the wrong temperature produces a coarse, uneven grain. Reheats are used freely rather than pushing a heat too far. Sulfur contamination from fuel, from lubricant or from marking materials attacks nickel alloys at forging heat, so N06003 stock is kept away from sulfur-bearing residues throughout the shop.
Chemical composition of UNS N06003
The limits below are the W.-Nr. 2.4869 / NiCr80-20 window we forge to, in weight percent. Every heat is supplied with a ladle analysis on the mill certificate; product analysis on the finished forging can be added on request.
| Element | Minimum % | Maximum % | Role in the alloy |
|---|---|---|---|
| Nickel (Ni) | 75.0 | balance | Base element. Gives the austenitic structure, the high resistivity and the resistance to nitriding |
| Chromium (Cr) | 19.0 | 21.0 | Forms the adherent Cr₂O₃ scale that carries the oxidation resistance to 1200 °C |
| Silicon (Si) | 0.75 | 1.75 | Deoxidiser. Raises resistivity and thickens the protective oxide |
| Manganese (Mn) | — | 1.00 | Deoxidiser; combines with residual sulfur |
| Iron (Fe) | — | 1.00 | Held low. Iron in the scale reduces oxide adhesion and shortens cyclic life |
| Cobalt (Co) | — | 1.50 | Residual limit, from nickel raw material |
| Copper (Cu) | — | 0.50 | Residual limit |
| Aluminium (Al) | — | 0.30 | Residual limit; small additions assist oxide formation |
| Carbon (C) | — | 0.15 | Kept low; excess carbon forms chromium carbide and depletes the oxide-forming chromium |
| Phosphorus (P) | — | 0.020 | Residual limit for hot workability |
| Sulfur (S) | — | 0.015 | Critical. Sulfur embrittles nickel alloys at temperature; we normally achieve ≤ 0.010 % |
Table compiled by Jiangyin Jiangnan Metal Co., Ltd. from the published W.-Nr. 2.4869 / NiCr80-20 specification. Some editions of DIN 17742 permit silicon to 2.00 %; state your required window on the enquiry and it will be confirmed on the order. Customer-specific restrictions are accepted.
Mechanical properties of UNS N06003 forgings
Certified minimums, solution annealed, 20 °C
These are the room-temperature values we certify for solution-annealed Alloy 80/20 forgings. They are minimums, not typical results.
| Property | Metric | Imperial |
|---|---|---|
| Tensile strength Rm, min | 650 MPa | 94 ksi |
| Yield strength Rp0.2, min | 280 MPa | 41 ksi |
| Elongation A5, min | 30 % | 30 % |
| Modulus of elasticity | 200 GPa | 29 × 10⁶ psi |
Typical as-delivered values
Solution-annealed forgings normally test above the specified minimums. The ranges below are representative of our production and move with section size and cooling rate; heavy sections sit at the lower end.
| Property | Typical range |
|---|---|
| Tensile strength | 650–800 MPa (94–116 ksi) |
| Yield strength 0.2 % | 280–400 MPa (41–58 ksi) |
| Elongation | 30–45 % |
| Hardness | typically below 200 HB in the annealed condition |
Typical values are for design screening only. The mill test certificate supplied with each forging governs acceptance. For sustained load at temperature, ask for creep or stress-rupture data for the specific section. Room-temperature strength is not the governing property in furnace service.
Physical and electrical properties
Electrical resistivity is what separates Alloy 80/20 from the other grades on this site. It sits at 1.12 Ω·mm²/m and hardly moves as the alloy heats, so a given section behaves much the same from cold start to full furnace temperature.
| Property | Metric | Imperial |
|---|---|---|
| Density | 8.30 g/cm³ | 0.300 lb/in³ |
| Melting temperature | approx. 1400 °C | approx. 2550 °F |
| Maximum service temperature, clean air | 1200 °C | 2190 °F |
| Modulus of elasticity | 200 GPa | 29 × 10⁶ psi |
| Specific heat capacity | 420 J/kg·K | 0.10 Btu/lb·°F |
| Thermal conductivity, 20 °C | 15 W/m·K | 104 Btu·in/ft²·h·°F |
| Mean coefficient of expansion, 20–100 °C | 12.5 µm/m·K | 6.9 × 10⁻⁶ in/in·°F |
| Electrical resistivity, 20 °C | 1.12 Ω·mm²/m (1.12 µΩ·m) | 674 Ω·circ mil/ft |
| Magnetic response | Essentially non-magnetic, annealed | |
| Hardenable by heat treatment | No. Solid-solution alloy with no ageing reaction | |
Nominal values compiled from published W.-Nr. 2.4869 datasheet data. Individual mill datasheets differ slightly: resistivity is quoted between 1.09 and 1.12 Ω·mm²/m and density between 8.30 and 8.31 g/cm³ depending on source.
Where UNS N06003 works, and where it fails
When this alloy disappoints in service, the cause is usually atmosphere rather than temperature or stress. The chromium oxide film does its job in oxidising and neutral gas. Once sulfur is present it does not, because nickel and nickel sulfide form a low-melting eutectic that runs along the grain boundaries. The table below is the short version.
| Atmosphere | Suitability | Comment |
|---|---|---|
| Clean air, oxygen-bearing gas | Excellent | Design case for the alloy. Continuous service to 1200 °C |
| Nitrogen, ammonia, cracked ammonia | Excellent | High nickel content gives good resistance to nitriding |
| Vacuum, argon, inert gas | Good | No protective oxide forms; check the design does not rely on the scale |
| Carburising gas | Good | Resistance to carburising is high; carbon pick-up is slow |
| Steam, water vapour | Acceptable | Oxide growth accelerates; derate the maximum temperature |
| Oxidising gas containing sulfur | Limited | Usable only well below the normal ceiling. Specify with care |
| Reducing gas containing sulfur | Not suitable | Rapid intergranular sulfidation. Use a low-nickel or cobalt-base grade |
| Molten salt, molten metal | Not suitable | Attacks the oxide film. Salt-bath hardware needs a different specification |
| Coded pressure service | Not applicable | No ASME BPVC allowable stress table exists for N06003 |
If your duty falls in a red row, tell us the atmosphere and temperature on the enquiry. We forge the full nickel-alloy range, and for sulfur-bearing or coded service the answer is usually Incoloy 800H, Haynes 188 or Haynes 230 rather than 80/20.
UNS N06003 compared with the alternatives
Enquiries for 80/20 often arrive when the real requirement is a different grade. These are the four alloys most often confused with it.
| Criterion | UNS N06003 Alloy 80/20 | Inconel 600 N06600 | Inconel 601 N06601 | Alloy 800H N08810 |
|---|---|---|---|---|
| Nominal Ni | 80 % | 72 % | 60 % | 32 % |
| Nominal Cr | 20 % | 16 % | 23 % | 21 % |
| Iron | ≤ 1 % | 6–10 % | balance | balance, ≥ 39.5 % |
| Electrical resistivity | 1.12 Ω·mm²/m | 1.03 Ω·mm²/m | 1.19 Ω·mm²/m | 0.99 Ω·mm²/m |
| ASME pressure code | no | yes | yes | yes, to 816 °C |
| Cyclic oxidation life | excellent | good | excellent | good |
| Creep-rupture strength | low | moderate | moderate | high |
| Relative cost per kg | high (nickel content) | high | moderate | lower |
| Choose it when | Furnace and heating hardware in clean air, resistance elements, cyclic duty | Corrosion plus strength, chloride and caustic service | Highest oxidation resistance at lower nickel cost | Sustained load above 593 °C, coded pressure parts |
In short: use UNS N06003 for non-pressure furnace hardware and resistance duty in clean air. Use Inconel 601 where the same oxidation resistance is wanted more cheaply and iron in the alloy is acceptable. Once the part carries load at red heat, or has to appear in a pressure-code calculation, use Alloy 800H.

Standards that cover UNS N06003
There is no dedicated ASTM or ASME forging specification for UNS N06003. That is worth knowing before you write the purchase order, because it changes how the item has to be specified. The published standards cover the alloy as heating conductor material in wire, ribbon, strip and bar form. Forgings are therefore ordered to the chemistry of W.-Nr. 2.4869, to a stated delivery condition, and to mechanical and NDT requirements agreed at the time of order.
| Document | Scope | Applies to forgings? |
|---|---|---|
| W.-Nr. 2.4869 | Material number and composition window for NiCr80-20 | Yes, chemistry basis |
| DIN 17742 | Wrought nickel alloys with chromium | Yes, chemistry and general requirements |
| DIN 17470 | Heating conductor alloys, properties and dimensions | Reference only |
| DIN 17471 | Resistance alloys for electrical purposes | Reference only |
| ASTM B344 | Drawn or rolled nickel-chromium alloys for electrical heating elements | Wire and ribbon only |
| EN 10204 | Types of inspection document | Yes, 3.1 standard and 3.2 on request |
| EN 10228-3 / SEP 1921 / ASTM A388 | Ultrasonic examination of forgings | Yes, NDT acceptance class |
| ASTM E112 | Determination of average grain size | Yes, when specified |
Recommended wording for an enquiry or purchase order: "Open-die forged component to drawing XXX, material UNS N06003 / W.-Nr. 2.4869, solution annealed, chemistry per DIN 17742, UT to EN 10228-3 class 3, certificate EN 10204 3.1." That gives an unambiguous, auditable specification without citing a standard that does not exist for the product form.
UNS N06003 forgings we produce
Jiangyin Jiangnan Metal Co., Ltd. is an open-die forging factory. Every item below is forged to the customer's drawing or dimensional sketch. There is no fixed catalogue, no tooling charge for open-die work and no minimum order quantity by piece, so one-off and prototype parts are economic.
Size and weight capability in this grade
| Product form | Dimensional range | Unit weight |
|---|---|---|
| Seamless rolled rings | OD 150–2,500 mm, height to 800 mm | 10–5,000 kg |
| Round bars | Ø 60–600 mm, length to 6,000 mm | 10–4,000 kg |
| Discs, tube sheets | Ø 150–1,800 mm, thickness to 500 mm | 15–6,000 kg |
| Shafts, sleeves, blocks | to 6,000 mm long | to 6,000 kg |
Capability shown is for UNS N06003 specifically; our overall plant envelope is larger. Equipment: 1 t, 3 t, 5 t and 9 t open-die forging hammers, hydraulic presses to 5,000 t, and 3 m and 6 m seamless ring-rolling mills. Machining allowance is normally 6–20 mm per surface depending on section size unless your drawing states otherwise. Finish-machined parts to print are also supplied.
How we make UNS N06003 forgings
- Melting. Alloy 80/20 stock is melted by EAF plus AOD or VOD refining. ESR remelting is available where the specification or service calls for improved cleanliness and reduced segregation; VIM + ESR + VAR is offered for the most demanding work.
- Chemistry verification. Heat chemistry is checked by spectrometer against the W.-Nr. 2.4869 window, with particular attention to sulfur and iron, before any material is heated.
- Open-die forging. Billets are heated to 1150–1180 °C in a low-sulfur atmosphere and forged on hydraulic presses and hammers with a controlled reduction ratio, closing porosity and developing a wrought grain flow that follows the part contour. Finish forging temperature is held above about 950 °C, with reheats as needed. Rings are ring-rolled seamless.
- Solution annealing. Held at approximately 1050 °C and rapidly cooled to give a uniform recrystallised grain. Alloy 80/20 is not age hardened, so no ageing step follows.
- Rough or finish machining. Turned, bored, drilled and faced to your drawing, with agreed machining allowance or to final dimensions.
- Non-destructive testing. Ultrasonic examination to EN 10228-3, SEP 1921, ASTM A388 or your nominated class; liquid penetrant and dimensional inspection as required.
- Certification and despatch. EN 10204 3.1 mill certificate as standard; 3.2 with third-party witness (TÜV, BV, LR, SGS, DNV) on request. Marked, preserved and packed for sea or air freight.
Where UNS N06003 forgings are used
| Industry | Components forged in UNS N06003 |
|---|---|
| Industrial electric furnaces | Element support rings and blocks, hearth rails, muffle and retort end rings, terminal and bushing forgings, door frame components |
| Enamelling and ceramic kilns | Furnace shell rings, hanger forgings, conveyor spindles and roller ends operating through repeated heat-up cycles |
| Heat treatment plant | Fixture and basket end forgings, grid supports, charge-carrier hardware, radiant tube end sleeves, thermocouple pockets |
| Electrical heating equipment | Forged terminals, connector blocks, high-temperature resistor and braking-resistor hardware, cartridge and tubular element end fittings |
| Glass and mineral processing | Hot-zone rings, bushings and support forgings in oxidising atmospheres |
| Environmental and process plant | Hot-gas ducting flanges, non-pressure nozzle bodies and support hardware in clean oxidising service |
| Laboratory and analytical | Furnace tube fittings, sample holders and hot-zone components where the atmosphere is air, nitrogen or ammonia |
All of these duties involve temperature cycling in an oxidising or neutral atmosphere at modest mechanical load. In that situation the adherent oxide of Alloy 80/20 earns its cost, and cheaper grades tend to fail by spalling rather than by melting or creeping.
Testing, inspection and certification
- Chemical analysis. Spectrometric heat analysis; product analysis on the finished forging on request.
- Mechanical testing. Room-temperature tensile and elongation as standard; elevated-temperature tensile, stress-rupture and impact testing to your specification.

Frequently asked questions about UNS N06003
What is UNS N06003?
UNS N06003 is the Unified Numbering System designation for the 80/20 nickel-chromium alloy, also known as Alloy 80/20, W.-Nr. 2.4869 and NiCr80-20. It contains at least 75 % nickel and 19–21 % chromium with almost no iron. It is austenitic, non-hardenable, and used for furnace and heating components in clean oxidising atmospheres up to about 1200 °C (2190 °F).
Is UNS N06003 the same as Nichrome 80/20?
Yes. Nichrome 80, Nichrome V, Chromel A, Nikrothal 80, Tophet A, Resistohm 80, Cronix 80, Cr20Ni80 and X20H80 all describe the same alloy specification as UNS N06003 and W.-Nr. 2.4869. Those names belong to individual producers. When ordering from any supplier, specify UNS N06003 or 2.4869 so the requirement is unambiguous and can be verified against the certificate.
Can UNS N06003 be forged into rings and discs?
Yes. Alloy 80/20 is readily open-die forged and ring rolled. Jiangyin Jiangnan Metal Co., Ltd. heats billets to 1150–1180 °C, forges above about 950 °C with reheats as required, and solution anneals at approximately 1050 °C. The alloy is more common as wire and strip, so forged rings, discs, bars and sleeves in this grade are normally made to order rather than held in stock.
What is the maximum service temperature of UNS N06003?
About 1200 °C (2190 °F) for continuous service in clean oxidising air. That figure assumes low mechanical load and an atmosphere free of sulfur. In steam, in sulfur-bearing gas or under sustained load, the practical ceiling is considerably lower. Melting begins at approximately 1400 °C, so there is only about 200 °C between the working ceiling and incipient melting.
Can UNS N06003 be hardened by heat treatment?
No. Alloy 80/20 is a single-phase solid-solution alloy with no precipitation-hardening reaction, so no solution-and-age cycle exists for it. Strength in wire and strip comes from cold work, which is lost on annealing or in service at temperature. Forgings are supplied solution annealed. If your design needs a heat-treatable nickel alloy, look at Nimonic 80A or Inconel X-750.
Which atmospheres damage UNS N06003?
Sulfur is the main hazard. In reducing gas containing sulfur, nickel and nickel sulfide form a low-melting phase that attacks grain boundaries and can destroy a component quickly, so the alloy should not be used there. Molten salts and molten metals also break down the oxide film. Air, nitrogen, ammonia, carburising gas and inert atmospheres are all suitable.
What is the difference between UNS N06003 and Inconel 600?
Inconel 600 (UNS N06600) contains about 72 % nickel, 16 % chromium and 6–10 % iron, and is a corrosion-resistant structural alloy with ASME pressure-code allowable stresses. UNS N06003 contains about 80 % nickel, 20 % chromium and almost no iron, has higher electrical resistivity and better cyclic-oxidation life, but no pressure-code coverage. Choose 600 for pressure-retaining or corrosion duty and N06003 for furnace and heating hardware.
Which standards cover UNS N06003 forgings?
There is no dedicated ASTM or ASME forging specification for this grade. Chemistry is defined by W.-Nr. 2.4869 and DIN 17742; ASTM B344, DIN 17470 and DIN 17471 cover the alloy as heating conductor wire, ribbon and strip. Forgings are therefore ordered to 2.4869 chemistry plus an agreed delivery condition, mechanical requirement and ultrasonic acceptance class, certified to EN 10204 3.1 or 3.2.
Do you supply a material certificate?
Every UNS N06003 forging ships with an EN 10204 3.1 mill test certificate as standard, showing heat number, chemical analysis, mechanical results, heat treatment record and NDT results. EN 10204 3.2 certification witnessed by a third party such as TÜV, BV, LR, SGS or DNV is available on request when the order is placed.
What is the lead time and the minimum order quantity?
Open-die forging needs no dies, so there is no tooling charge and no piece minimum, so single prototype parts are economic. Lead time depends on raw material availability. Where suitable 80/20 stock is on hand, simple rings and discs typically run 25–40 days. A new melt, ESR remelting, heavy machining or third-party witnessed inspection extends that. Send the drawing and a firm date is confirmed with the quotation.
