Material number · Europe · 2 designations # 2.4810 2.4810 is the material number of the grade also listed as NiMo 30. It is a material in the category Nickel and cobalt alloys. We list 2 designations recorded for this grade, in the standards DIN / EN and UNS. - ***Material no.* **2.4810**** - [*Category* **Nickel and cobalt alloys · 87 grades**](/categories/nickel-and-cobalt-alloys "Category: Nickel and cobalt alloys · 87 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c2070ae0-3a8e-4adb-b4c5-5b543f9c6ea9 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/2.4810.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [UNS N10001 This grade’s own name · 4 grades on that route](/materials/uns/n10001 "UNS N10001") ## About Nickel and cobalt alloys Nickel and cobalt alloys are metallic materials whose properties are developed through nickel-, cobalt-, or combined alloying systems. They are characterised by strong resistance to corrosion, oxidation, wear, and loss of strength at elevated temperatures, making them suitable for turbine components, chemical-processing equipment, and other demanding high-temperature applications. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 2 designations · 2 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once. DIN / EN Europe · 1 - [NiMo 30 This grade’s own name Withdrawn](/materials/din-en/nimo-30 "DIN / EN NiMo 30") UNS United States · 1 - [N10001 This grade’s own name](/materials/uns/n10001 "UNS N10001") Every designation on file is listed — no truncation, no “+ n more”. Each one is itself a route that leads back here. ## Chemical composition 12 elements on file · weight % What this alloy is Fe Ni Mo Co Iron — the balance, never listed by a standard — 3.8 % Ni — 62 % Mo — 28 % Co — 2.5 % Traces & impurities · 3.7 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.05 | | Si | ≤ 0.5 | | Mn | ≤ 1 | | P | 0.03 | | S | 0.015 | | Cr | ≤ 1 | | Mo | 26–30 | | Ni | ≥ 62 | | V | ≤ 0.6 | | Co | ≤ 2.5 | | Cu | ≤ 0.5 | | Fe | 4–7 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Vanadium Cobalt Copper Iron 0.01 % 0.1 % 1 % 10 % 100 % The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other. | Element | As published source text, verbatim | Min% by weight | Max% by weight | Bound | |---|---|---|---|---| | C | ≤0,05 | — | 0.050 | Max | | Si | ≤0,50 | — | 0.500 | Max | | P | 0,03 | 0.030 | 0.030 | Exact | | S | 0,015 | 0.015 | 0.015 | Exact | | V | ≤0,60 | — | 0.600 | Max | | Cr | ≤1,00 | — | 1.000 | Max | | Mn | ≤1,00 | — | 1.000 | Max | | Fe | 4,00-7,00 | 4.000 | 7.000 | Range | | Co | ≤2,50 | — | 2.500 | Max | | Ni | ≥62,0 | 62.000 | — | Min | | Cu | ≤0,50 | — | 0.500 | Max | | Mo | 26,0-30,0 | 26.000 | 30.000 | Range | The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni. ## Physical & mechanical properties Density 7,85 g/cm³ Exact An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 2.4, a shared category, and a published range for Ni / Mo that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
