Their alloying provides resistance to creep, oxidation, and thermal degradation, making them suitable for aircraft engine and other hot-section components. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Chemical composition 14 elements on file · weight % What this alloy is Fe Cr Co Mn Iron — the balance, never listed by a standard — 79.3 % Cr — 10.5 % Co — 6 % Mn — 0.8 % Traces & impurities · 3.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.05–0.12 | | Si | 0.1–0.8 | | Mn | 0.3–1.3 | | P | 0.025 | | S | 0.015 | | Cr | 9.8–11.2 | | Mo | 0.5–1 | | Ni | 0.2–1.2 | | V | 0.1–0.4 | | W | ≤ 0.7 | | Co | 5–7 | | Nb | 0.2–0.5 | | N | 0.035 | | B | 0.005–0.015 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Vanadium Tungsten Cobalt Niobium Nitrogen Boron 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 | |---|---|---|---|---| | B | 0,005-0,015 | 0.005 | 0.015 | Range | | C | 0,05-0,12 | 0.050 | 0.120 | Range | | N | 0,035 | 0.035 | 0.035 | Exact | | Si | 0,10-0,80 | 0.100 | 0.800 | Range | | P | 0,025 | 0.025 | 0.025 | Exact | | S | 0,015 | 0.015 | 0.015 | Exact | | V | 0,10-0,40 | 0.100 | 0.400 | Range | | Cr | 9,80-11,2 | 9.800 | 11.200 | Range | | Mn | 0,30-1,30 | 0.300 | 1.300 | Range | | Co | 5,00-7,00 | 5.000 | 7.000 | Range | | Ni | 0,20-1,20 | 0.200 | 1.200 | Range | | Nb | 0,20-0,50 | 0.200 | 0.500 | Range | | Mo | 0,50-1,00 | 0.500 | 1.000 | Range | | W | ≤0,70 | — | 0.700 | Max | 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?
