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. ## Chemical composition 10 elements on file · weight % What this alloy is Fe Cr Ni Mo Iron — the balance, never listed by a standard — 54.9 % Cr — 25.5 % Ni — 9 % Mo — 5 % Traces & impurities · 5.6 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 1 — Unusual | | Si | ≤ 1 | | Mn | ≤ 1.5 | | Cr | 23.5–27.5 | | Mo | 4–6 | | Ni | 7–11 | | W | 1–3 | | Co | Balance | | N | 0.12 | | Fe | 1–3 | Carbon Silicon Manganese Chromium Molybdenum Nickel Tungsten Cobalt Nitrogen 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 | ≤1,00 | — | 1.000 | Max | | N | 0,12 | 0.120 | 0.120 | Exact | | Si | ≤1,00 | — | 1.000 | Max | | Cr | 23,5-27,5 | 23.500 | 27.500 | Range | | Mn | ≤1,50 | — | 1.500 | Max | | Fe | 1,00-3,00 | 1.000 | 3.000 | Range | | Co | Rest/Bal. | 45.880 | 63.380 | Balance | | Ni | 7,00-11,0 | 7.000 | 11.000 | Range | | Mo | 4,00-6,00 | 4.000 | 6.000 | Range | | W | 1,00-3,00 | 1.000 | 3.000 | 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 This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here. ## Physical & mechanical properties Density 8,48 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 Co / Cr 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.
