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 — 46.6 % Cr — 20 % Ni — 20 % Mo — 4 % Traces & impurities · 9.5 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≈ 0.4 — Unusual | | Si | ≈ 0.3 | | Mn | ≈ 0.75 | | Cr | ≈ 20 | | Mo | ≈ 4 | | Ni | ≈ 20 | | W | 4 | | Co | Balance | | Nb | ≈ 4 — Unusual | | Fe | ≈ 3 | Carbon Silicon Manganese Chromium Molybdenum Nickel Tungsten Cobalt Niobium 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 | ~0,40 | 0.400 | 0.400 | Indicative | | Si | ~0,30 | 0.300 | 0.300 | Indicative | | Cr | ~20,0 | 20.000 | 20.000 | Indicative | | Mn | ~0,75 | 0.750 | 0.750 | Indicative | | Fe | ~3,00 | 3.000 | 3.000 | Indicative | | Co | Rest/Bal. | 43.550 | 43.550 | Balance | | Ni | ~20,0 | 20.000 | 20.000 | Indicative | | Nb | ~4,00 | 4.000 | 4.000 | Indicative | | Mo | ~4,00 | 4.000 | 4.000 | Indicative | | W | 4 | 4.000 | 4.000 | Exact | 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 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. ## Looking for this grade under another name?
