X10NiCrAlTi32-20 Forgings
Seamless rolled rings, flanges, round bars, discs, shafts, sleeves, bushings and tube sheets, open-die forged to EN 10095 and DIN 17460.
X10NiCrAlTi32-20 (material number 1.4876) is a heat resisting austenitic nickel-iron-chromium alloy containing 30 to 34% nickel, 19 to 23% chromium, 0.15 to 0.60% aluminium and 0.15 to 0.60% titanium, with the balance iron. The grade is specified in DIN 17460 and appears in EN 10095 under the name X10NiCrAlTi32-21. It resists oxidation, carburisation and sulfidation, and holds useful creep strength. The high nickel content gives much better resistance to chloride stress-corrosion cracking than 304 or 316 stainless steel. Loaded parts are used up to 816 °C (1500 °F). Unstressed parts in air run to about 1100 °C.

What X10NiCrAlTi32-20 is, and when to specify it
X10NiCrAlTi32-20 belongs to the group of iron-nickel-chromium alloys used for long-term service at high temperature. It is about one third nickel and one fifth chromium, with the rest iron. The iron base makes it cheaper per kilogram than nickel-base alloys such as Inconel 617 or Haynes 230. The structure stays austenitic across the whole working range and does not transform or embrittle.
Chromium forms the protective oxide. That oxide provides the resistance to oxidation, to carburisation in reducing carbon-rich atmospheres, and to sulfidation. Nickel stabilises the austenite and supplies the resistance to chloride stress-corrosion cracking, which is the usual reason 304 and 316 fail in hot chloride-bearing process streams. Aluminium and titanium are added in small controlled amounts. They tie up carbon and nitrogen and help keep the structure stable at temperature.
The normal working band is roughly 550 °C to 900 °C. Below 550 °C an austenitic stainless steel is usually enough and costs less. Above about 950 °C on a loaded part, a nickel-base alloy is normally needed. Between those limits X10NiCrAlTi32-20 gives adequate creep strength, dimensional stability and oxidation life at a lower alloy cost.
Note one point when writing the purchase order. The 1.4876 chemistry sets a carbon minimum of 0.06%. This places it in the upper half of the Alloy 800 carbon range, closer to Alloy 800H than to standard Alloy 800. If the part carries load for tens of thousands of hours above 593 °C, state the coarse-grain solution anneal on the order as well. Carbon on its own does not deliver creep strength without the matching grain size.
Chemical composition of X10NiCrAlTi32-20 (1.4876)
The limits below are the specification range we forge to, expressed 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. The two highlighted rows are the additions that separate this grade from a plain austenitic stainless steel.
| Element | Min % | Max % | Role in the alloy |
|---|---|---|---|
| Nickel (Ni) | 30.00 | 34.00 | Stabilises the austenitic matrix and supplies the resistance to chloride stress-corrosion cracking |
| Chromium (Cr) | 19.00 | 23.00 | Forms the protective oxide against oxidation, carburisation and sulfidation |
| Iron (Fe) | balance | — | Base element, typically 39.5% or more. Keeps the alloy cheaper than nickel-base grades |
| Carbon (C) | 0.06 | 0.12 | Held deliberately high for creep strength. The 0.06% minimum places 1.4876 close to Alloy 800H |
| Aluminium (Al) | 0.15 | 0.60 | Works with titanium to give high-temperature structural stability |
| Titanium (Ti) | 0.15 | 0.60 | Ties up carbon and nitrogen and contributes to rupture strength |
| Manganese (Mn) | — | 2.00 | Deoxidiser, combines with sulfur |
| Silicon (Si) | — | 1.00 | Deoxidiser, assists oxidation resistance |
| Phosphorus (P) | — | 0.030 | Residual, kept low for hot workability |
| Sulfur (S) | — | 0.015 | Kept low for hot workability and toughness |
| Copper (Cu) | — | 0.75 | Controlled as a residual, not restricted by the grade limits |
Aluminium plus titanium is not restricted as a combined figure in 1.4876. If your specification calls for a combined Al plus Ti window, 0.30 to 1.20% for Alloy 800H or 0.85 to 1.20% for Alloy 800HT, state it on the enquiry. We will then select a heat that satisfies both the European and the ASTM requirement so one forging can be dual-certified.
Mechanical properties of X10NiCrAlTi32-20 forgings
Specified room-temperature values, solution annealed
These are the values a mill certificate must meet. They are specification limits, not typical test results.
| Property | Metric | Imperial |
|---|---|---|
| 0.2% proof strength (Rp0.2), min | ≥ 170 MPa | ≥ 25 ksi |
| Tensile strength (Rm) | 450 to 680 MPa | 65 to 99 ksi |
| Elongation (A), min | ≥ 30 % | ≥ 30 % |
| Hardness, max | ≤ 192 HB | ≤ 192 HB |
Tensile strength is given as a band, with an upper limit as well as a lower one. High strength in this grade indicates a fine grain or an incomplete anneal, and both shorten creep life.
Indicative 0.2% proof strength at temperature
Hot strength falls steadily as temperature rises. The figures below are indicative minimum values for design screening.
| Temperature | 100 °C | 200 °C | 300 °C | 400 °C | 500 °C | 600 °C | 700 °C | 800 °C |
|---|---|---|---|---|---|---|---|---|
| Rp0.2, MPa | 145 | 135 | 125 | 115 | 110 | 105 | 100 | 90 |
Table 3 is not design data. Above roughly 593 °C the governing property becomes creep-rupture strength. Take the allowable stress from the applicable design code: EN 13445, VdTÜV Wbl. 412, or ASME BPVC Section II Part D for the equivalent UNS grade. Send us the design temperature, the design life and the code, and we will confirm what the material has to be certified to.

X10NiCrAlTi32-20 compared with Alloy 800, 800H and 800HT
These grades are often confused on drawings and purchase orders. Nickel, chromium and iron content are effectively the same across all of them, and so is corrosion behaviour. The differences are carbon content, the combined aluminium and titanium window, the required grain size and the anneal temperature. Those four items decide how the material behaves under sustained load at high temperature.

| Governing property | room-temperature strength, or creep if coarse-grain annealed | room-temperature strength | creep and rupture | creep and rupture, highest allowables |
| Specify it when | The drawing or code is written to DIN or EN and 1.4876 is called out by material number | 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 |
Ordering note. If your drawing says 1.4876 or X10NiCrAlTi32-20, order to the material number and state the service temperature. If the part is loaded above 593 °C, ask for a coarse-grain anneal and dual certification to Alloy 800H or Alloy 800HT so one forging satisfies both the European and the ASTM requirement.

How we make X10NiCrAlTi32-20 forgings
- MeltingX10NiCrAlTi32-20 stock is melted by EAF plus AOD or VOD refining. ESR remelting is added where the specification or the service condition calls for improved cleanliness and reduced segregation.
- Ingot and billet verificationHeat chemistry is verified by spectrometer against the 1.4876 limits, including the aluminium and titanium windows, before any material is charged into the furnace.
- Open-die forgingForged 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 annealingSolution annealed and rapidly cooled. The standard range is 980 to 1050 °C. Where creep strength governs, a coarse-grain anneal at 1100 to 1150 °C is used instead. X10NiCrAlTi32-20 is a solid-solution alloy and is not precipitation hardened, so no ageing treatment is applied.
- Rough or finish machiningTurned, bored, drilled and faced to your drawing, with an agreed machining allowance or to final dimensions.
- Non-destructive testingUltrasonic examination to EN 10228-3, SEP 1921, ASTM A388 or your nominated class. Liquid penetrant and dimensional inspection as required.
- Certification and despatchEN 10204 3.1 mill certificate as standard. EN 10204 3.2 with third-party witness from TÜV, BV, LR, SGS or DNV on request. Hard stamped, preserved and packed for sea or air freight.

Frequently asked questions about X10NiCrAlTi32-20
What is X10NiCrAlTi32-20?
X10NiCrAlTi32-20 (material number 1.4876) is a heat resisting austenitic nickel-iron-chromium alloy. It contains 30 to 34% nickel, 19 to 23% chromium, 0.15 to 0.60% aluminium and 0.15 to 0.60% titanium, with the balance iron. The grade is specified in DIN 17460 and appears in EN 10095 as X10NiCrAlTi32-21. It resists oxidation, carburisation and sulfidation, holds useful creep strength, and resists chloride stress-corrosion cracking far better than 304 or 316 stainless steel.
What is the material number for X10NiCrAlTi32-20?
The Werkstoff number is 1.4876. The same material number is carried by the EN 10095 designation X10NiCrAlTi32-21, which replaced the older DIN 17460 name X10NiCrAlTi32-20. Both names refer to the same alloy. Order to material number 1.4876 to avoid ambiguity.
Is X10NiCrAlTi32-20 the same as Incoloy 800?
They are the same alloy family and the chemistries overlap almost completely. X10NiCrAlTi32-20 (1.4876) is the European designation, Alloy 800 (UNS N08800) is the American one, and Incoloy 800 is the trade name of Special Metals Corporation. The difference is that 1.4876 sets a carbon minimum of 0.06%, which places it in the higher-carbon part of the range and closer to Alloy 800H. Where a pressure code or a design registration is involved, order to both the material number and the UNS number, and confirm the equivalence on the mill certificate.
What is the maximum service temperature of X10NiCrAlTi32-20?
For load-bearing and pressure-retaining parts, 816 °C (1500 °F) is the normal design ceiling. This matches the ASME Section VIII Division 1 allowable stress tables for the Alloy 800 family. For non-load-bearing parts such as furnace fixtures and radiant tube supports, oxidation sets the limit and the scaling temperature in air is about 1100 °C. Above roughly 593 °C, design on creep and stress-rupture strength rather than room-temperature strength.
What is the chemical composition of X10NiCrAlTi32-20?
Carbon 0.06 to 0.12%, silicon 1.00% max, manganese 2.00% max, phosphorus 0.030% max, sulfur 0.015% max, nickel 30.00 to 34.00%, chromium 19.00 to 23.00%, aluminium 0.15 to 0.60%, titanium 0.15 to 0.60%, iron balance. All figures are weight percent. Table 1 above lists the role each element plays.
What are the mechanical properties of X10NiCrAlTi32-20?
In the solution annealed condition the specified room-temperature values are a 0.2% proof strength of at least 170 MPa (25 ksi), a tensile strength of 450 to 680 MPa (65 to 99 ksi), elongation of at least 30%, and hardness not exceeding 192 HB. Typical production results sit above the minimums. Tensile strength carries an upper limit as well as a lower one, because high strength indicates a fine grain or an incomplete anneal.
Which heat treatment is correct for X10NiCrAlTi32-20 forgings?
Solution annealing followed by rapid cooling. The standard range is 980 to 1050 °C. Where the part carries sustained load above 593 °C and creep strength governs, a higher coarse-grain anneal of 1100 to 1150 °C is used instead, to produce an ASTM No. 5 or coarser grain size. X10NiCrAlTi32-20 is a solid-solution alloy and is not precipitation hardened, so no ageing treatment is applied. An ageing cycle would add nothing and would waste furnace time.
Can X10NiCrAlTi32-20 be welded?
Yes. X10NiCrAlTi32-20 is readily welded by GTAW, GMAW and SMAW. Filler metals based on Inconel 82 or Inconel 617 are commonly specified for high-temperature service, because a matching filler does not develop the same rupture strength across the weld. Post-weld heat treatment is not normally required for the alloy itself, although the design code may call for it. Keep heat input moderate and interpass temperature low.
What sizes of X10NiCrAlTi32-20 forgings can you supply?
Seamless rolled rings from 200 to 3,000 mm outside diameter, round bars from 80 to 800 mm diameter and up to 6,000 mm long, discs and tube sheets to 2,500 mm diameter and 600 mm thick, and shafts, sleeves and blocks to 6,000 mm long, at unit weights from 20 kg to about 10,000 kg. Open-die forging needs no dies, so one-off and prototype quantities are economic. There is no tooling charge and no minimum order quantity by piece.
Do you supply an EN 10204 3.1 or 3.2 certificate?
Every X10NiCrAlTi32-20 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 at the time of order.
How long does an X10NiCrAlTi32-20 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 to 40 days. Parts needing a new melt, ESR remelting, heavy machining or third-party witnessed inspection take longer. Send your drawing and we will confirm a firm date with the quotation.
