UNS N08811 Forgings
Open-die forged seamless rolled rings, flanges, round bars, discs, shafts, sleeves, bushings and tube sheets in UNS N08811, supplied solution annealed to ASTM B564 / ASME SB-564.
UNS N08811 is a nickel-iron-chromium alloy containing 30.0–35.0 % nickel, 19.0–23.0 % chromium and 39.5 % iron minimum, with carbon controlled to 0.06–0.10 % and combined aluminium plus titanium to 0.85–1.20 %. It is the UNS number for the grade commonly sold as Alloy 800HT or Incoloy® 800HT, and it is registered as W.Nr. 1.4959 / X8NiCrAlTi32-21 in the European system. Forgings in UNS N08811 are covered by ASTM B564 and ASME SB-564, and are solution annealed at 1149 °C (2100 °F) minimum to an ASTM No. 5 or coarser grain size. Carbon, combined aluminium plus titanium and the anneal temperature are the three controls behind the creep-rupture strength of the grade above 593 °C (1100 °F).

The four temperatures that define UNS N08811
These four thresholds set the requirements in the specification.
What UNS N08811 is, and what the number means
UNS N08811 is an entry in the Unified Numbering System for Metals and Alloys, jointly maintained by ASTM International and SAE International. The letter N marks a nickel or nickel-bearing alloy; the 088xx block holds the iron-nickel-chromium grades of the Alloy 800 family. Three members of that block appear on most drawings:
- UNS N08800 (Alloy 800), for service up to about 593 °C (1100 °F).
- UNS N08810 (Alloy 800H), the controlled-carbon, coarse-grain version for higher temperatures.
- UNS N08811 (Alloy 800HT), the same chemistry as 800H but with aluminium plus titanium restricted to 0.85–1.20 % and a higher minimum anneal.
All three have effectively the same nickel, chromium and iron content, and behave almost identically in corrosion. What separates them is carbon, combined aluminium plus titanium and anneal temperature. Those three decide how the material holds load at red heat. Below roughly 593 °C, short-term tensile strength governs the design and Alloy 800 is normally sufficient and cheaper. Above it, creep and stress-rupture strength take over, and UNS N08811 is the grade that carries the higher allowable design stresses.
Because UNS N08811 sits inside the composition window of UNS N08810, a heat that meets N08811 also meets N08810. The reverse is not true. Most of the material Jiangyin Jiangnan Metal forges is therefore dual-certified to both numbers, so a single forging satisfies a drawing written to either grade.
A note on spelling. The designation carries the digit zero, N08811. It is frequently typed with the letter O instead, giving UNS NO8811, and it also reaches us as N 08811 or plain 08811 on enquiries and purchase orders. All refer to the same alloy. If you have received a drawing using one of these variants, quote it back as UNS N08811 to avoid ambiguity at goods-inward inspection.
UNS N08811 chemical composition
Composition limits for UNS N08811 per ASTM B564 / ASME SB-564 (forgings) and ASTM B408 (bar), in weight percent. The two highlighted rows are the composition controls that separate N08811 from N08800 and N08810; the third control is the anneal temperature.
| Element | Minimum % | Maximum % | Role in the alloy |
|---|---|---|---|
| Nickel (Ni) | 30.00 | 35.00 | Stabilises the austenitic matrix; resists chloride stress-corrosion cracking |
| Chromium (Cr) | 19.00 | 23.00 | Forms the protective oxide against oxidation, sulfidation and carburisation |
| Iron (Fe) | 39.50 | balance | Base element; keeps the alloy cheaper than nickel-base grades |
| Carbon (C) | 0.06 | 0.10 | Held deliberately high for creep strength. Tighter than N08810 (0.05–0.10) |
| Aluminium (Al) | 0.15 | 0.60 | Combines with titanium for high-temperature structural stability |
| Titanium (Ti) | 0.15 | 0.60 | Ties up carbon and nitrogen; contributes to rupture strength |
| Aluminium + Titanium | 0.85 | 1.20 | The defining restriction of N08811. N08810 allows 0.30–1.20 |
| Manganese (Mn) | — | 1.50 | Deoxidiser; combines with sulfur |
| Silicon (Si) | — | 1.00 | Deoxidiser; assists oxidation resistance |
| Copper (Cu) | — | 0.75 | Residual limit |
| Sulfur (S) | — | 0.015 | Kept low for hot workability and toughness |

A common transcription error. Several published UNS N08811 tables list titanium as 0.25–0.60 % and aluminium as 0.85–1.20 %. That collapses the combined Al + Ti restriction into the aluminium row. In the standard, aluminium and titanium each run 0.15–0.60 %, and it is their sum that must fall between 0.85 and 1.20 %. If a mill certificate shows aluminium alone above 0.60 %, the heat is out of specification, not conforming.
Every heat Jiangyin Jiangnan Metal forges is supplied with a ladle analysis on the mill certificate. The Al + Ti sum is worked out and printed on the certificate, so the buyer does not have to add it up. Product analysis on the finished forging can be added on request.

UNS N08800 vs N08810 vs N08811
These three UNS numbers are routinely confused on drawings and purchase orders. They differ in three things only: carbon content, combined aluminium plus titanium, and anneal temperature.
| Criterion | UNS N08800 | UNS N08810 | UNS N08811 |
|---|---|---|---|
| Common name | Alloy 800 | Alloy 800H | Alloy 800HT |
| Werkstoff Nr. | 1.4876 | 1.4958 | 1.4959 |
| Carbon, % | 0.10 max | 0.05–0.10 | 0.06–0.10 |
| Al + Ti, % | not restricted | 0.30–1.20 | 0.85–1.20 |
| Grain size requirement | none specified | ASTM No. 5 or coarser | ASTM No. 5 or coarser |
| Minimum anneal | ~980 °C | ≥1121 °C (2050 °F) | ≥1149 °C (2100 °F) |
| Normal service ceiling | 593 °C / 1100 °F | above 593 °C | above 593 °C |
| Governing property | room-temperature strength | creep and rupture | creep and rupture, highest allowables |
| Specify it when | Service stays below 593 °C and cost matters | Sustained high-temperature service, standard code allowables | Long-term load above 593 °C, or the code requires the higher allowable stress |
The practical rule: for service below 593 °C specify UNS N08800; for sustained load above 593 °C specify UNS N08811 and ask for dual N08810 / N08811 certification. Dual certification costs nothing extra, and it means the same forging can be released against a drawing written to either number.

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. Forging is carried out on open-die hydraulic presses supported by 1, 3, 5 and 9 tonne hammers, with 3 m and 6 m seamless ring-rolling mills, in-house heat treatment, machining and a testing laboratory.
How UNS N08811 forgings are made
The route below is the standard sequence for a UNS N08811 forging at Jiangyin Jiangnan Metal Co., Ltd. Steps are added or witnessed as your specification requires.
- Melting UNS N08811 stock is melted by EAF + AOD/VOD. ESR remelting is available where the specification or the service calls for improved cleanliness and reduced segregation.
- Heat verification Heat chemistry is checked by spectrometer against the ASTM B564 limits, including the Al + Ti window that defines the grade, before any material is heated for forging.
- Open-die forging Forged on hydraulic presses with a controlled reduction ratio to close porosity and develop a wrought grain flow that follows the part contour. Rings are ring-rolled seamless.
- Solution annealing Held at 1149 °C (2100 °F) minimum, then rapidly cooled. This produces the ASTM No. 5 or coarser grain size that carries the creep strength of the grade. UNS N08811 is a solid-solution alloy and is never age-hardened.
- Rough or finish machining Turned, bored, drilled and faced to your drawing, with the agreed machining allowance or to final dimensions.
- Non-destructive testing Ultrasonic examination to EN 10228-3, SEP 1921, ASTM A388 or your nominated class, plus penetrant and dimensional inspection as required.
- Certification and despatch EN 10204 3.1 mill certificate as standard, 3.2 with third-party witness on request. Hard stamped, preserved and packed for sea or air freight.
Where UNS N08811 forgings are used
| Industry | Components forged in UNS N08811 |
|---|---|
| Petrochemical and refining | Ethylene cracking furnace headers and outlet fittings, hydrogen reformer pigtail connections, transfer line exchanger components, forged nozzles and flanges |
| Power generation | Superheater and reheater header forgings, steam-side flanges, tube sheets, valve bodies for high-temperature steam |
| Industrial furnaces and heat treatment | Radiant tube components, retort and muffle end rings, fixture and basket hardware, roller ends |
| Chemical processing | Nitric and sulfuric acid plant hardware, ammonia and urea plant exchanger forgings, catalyst grid supports |
| Pressure vessels and heat exchangers | Forged tube sheets, shell flanges, blind covers and girth rings for shell-and-tube exchangers |
| Nuclear | Steam generator tube sheet forgings and heat exchanger components under Section III Code Cases N-201, N-253 and N-254 |
UNS N08811 is chosen for these duties because it resists oxidation, carburisation and sulfidation at temperature and stays dimensionally stable under long-term load. It does not form embrittling sigma phase in the way some higher-chromium stainless grades do. The iron base also makes it cheaper per kilogram than nickel-base alternatives such as Inconel 617 or Haynes 230.
Testing, inspection and certification
- Chemical analysis. Spectrometric heat analysis with the Al + Ti sum reported; product analysis on the finished forging on request.
- Mechanical testing. Room-temperature tensile, yield and elongation per ASTM B564; elevated-temperature tensile, stress-rupture and impact testing to your specification.
- Grain size. Determined per ASTM E112. ASTM No. 5 or coarser is mandatory for UNS N08811 and is reported on the certificate.
- Ultrasonic testing. EN 10228-3, SEP 1921 Class C / D / E, ASTM A388 or your nominated customer class.
- Surface NDT. Liquid penetrant examination per ASTM E165 or ASME Section V Article 6.
- Intergranular corrosion. ASTM A262 practice as agreed at order stage.
- Certification. EN 10204 3.1 as standard; EN 10204 3.2 witnessed by TÜV, BV, LR, SGS or DNV on request. Full heat traceability and hard stamping on every piece.
How to specify UNS N08811 on a purchase order
An incomplete line on the order causes more requotes on this grade than any technical question does. A complete UNS N08811 forging line carries seven items:
- Grade and standard. Write “UNS N08811 to ASTM B564”. Add “dual certified to UNS N08810” if the drawing may be released against either number.
- Product form and dimensions. Rough forged size with machining allowance, or finish-machined dimensions with the drawing number and revision.
- Delivery condition. Solution annealed at 1149 °C (2100 °F) minimum, rapidly cooled. State if a specific cooling medium is required.
- Grain size. ASTM No. 5 or coarser per ASTM E112, reported on the certificate.

Frequently asked questions about UNS N08811
What is UNS N08811?
UNS N08811 is the Unified Numbering System designation for a nickel-iron-chromium alloy containing 30.0–35.0 % nickel, 19.0–23.0 % chromium and a minimum of 39.5 % iron, with carbon controlled to 0.06–0.10 % and combined aluminium plus titanium to 0.85–1.20 %. It is the same material sold under the names Alloy 800HT and Incoloy® 800HT, and is registered as W.Nr. 1.4959 in the European system. UNS N08811 is used above 593 °C (1100 °F) where creep and stress-rupture strength govern the design.
Is UNS N08811 the same as Incoloy 800HT?
Yes. UNS N08811, Alloy 800HT and Incoloy® 800HT all refer to the same material specification. Incoloy® is a registered trademark of Special Metals Corporation; “Alloy 800HT” is the generic name used when the material is supplied by a producer other than the trademark holder. When ordering, specify UNS N08811 and ASTM B564 so the requirement is unambiguous regardless of who supplies it.
What is the difference between UNS N08810 and UNS N08811?
Both are high-temperature versions of Alloy 800. UNS N08810 (Alloy 800H) allows 0.05–0.10 % carbon and 0.30–1.20 % aluminium plus titanium. UNS N08811 (Alloy 800HT) tightens those to 0.06–0.10 % carbon and 0.85–1.20 % Al + Ti, and requires a solution anneal of at least 1149 °C (2100 °F) instead of 1121 °C. The result is higher creep-rupture strength and a higher allowable design stress. Because the N08811 window sits inside the N08810 window, an N08811 heat also satisfies N08810, which is why dual certification is standard practice.
What is the maximum service temperature of UNS N08811?
For pressure-retaining parts, the ASME Boiler and Pressure Vessel Code Section VIII Division 1 assigns maximum allowable stresses for UNS N08811 up to 816 °C (1500 °F), and Code Case 1983 extends this to 982 °C (1800 °F). For non-pressure parts such as furnace fixtures and retort hardware, the practical limit is set by oxidation and by the applied load, and continuous service near 1000 °C is common. Below 593 °C (1100 °F), UNS N08800 is the more economical choice.
What is the chemical composition of UNS N08811?
Per ASTM B564 and ASTM B408: nickel 30.0–35.0 %, chromium 19.0–23.0 %, iron 39.5 % minimum, carbon 0.06–0.10 %, aluminium 0.15–0.60 %, titanium 0.15–0.60 %, aluminium plus titanium 0.85–1.20 %, manganese 1.50 % max, silicon 1.00 % max, copper 0.75 % max and sulfur 0.015 % max. Note that aluminium and titanium each run 0.15–0.60 %; it is their sum that must fall between 0.85 and 1.20 %.
Which heat treatment is correct for UNS N08811 forgings?
Solution annealing at 1149 °C (2100 °F) minimum, followed by rapid cooling. UNS N08811 is a solid-solution alloy and is not precipitation hardened, so no ageing treatment is applied. The high anneal coarsens the grain to ASTM No. 5 or larger, which is what delivers the creep-rupture strength. Annealing below that temperature produces a fine grain, and the forging then fails the grain size requirement of ASTM B564 regardless of how good the chemistry is.
Can UNS N08811 be welded?
Yes. UNS N08811 is readily welded by GTAW, GMAW and SMAW. For high-temperature service, filler metals based on Inconel 617 or Inconel 82 are commonly specified, because a matching 800HT filler does not develop the same rupture strength across the weld. Post-weld heat treatment is not normally required for the alloy itself, though the design code may call for it.
What does the spelling “UNS NO8811” mean?
It is the same alloy. The designation is correctly written with the digit zero, N08811, but the letter O is often typed by mistake, producing “UNS NO8811”. The forms “N 08811” and “08811” also appear on enquiries. All refer to UNS N08811 / Alloy 800HT. Quote it back as UNS N08811 on the order to avoid ambiguity at goods-inward inspection.
What sizes of UNS N08811 forgings can you supply?
Jiangyin Jiangnan Metal Co., Ltd. forges UNS N08811 seamless rolled rings from 200 mm to 3,000 mm outside diameter, round bars from Ø80 mm to Ø800 mm and up to 6,000 mm long, discs and tube sheets from Ø200 mm to Ø2,500 mm and up to 600 mm thick, and shafts, sleeves and blocks up to 6,000 mm long. Unit weights run from 20 kg to 10,000 kg. Because this is open-die work, there is no tooling charge and no minimum order quantity by piece, so one-off and prototype forgings are economic.
Do you supply a material certificate with UNS N08811 forgings?
Every UNS N08811 forging ships with an EN 10204 3.1 mill test certificate as standard, showing heat number, chemical analysis including the Al + Ti sum, mechanical results, grain size, 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 at the time of order.
How long does a UNS N08811 forging take to produce?
Lead time depends on whether the grade is in raw stock and on the size of the forging. Simple rings and discs from stock material typically run 25–40 days. Parts needing a new melt, ESR remelting, heavy machining or third-party witnessed inspection take longer. Send a drawing and Jiangyin Jiangnan Metal will confirm a firm date with the quotation.
