Their composition and mechanical behaviour vary by grade, and they are used for corrosion-resistant cast components such as pumps, valves and process equipment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Chemical composition 8 elements on file · weight % What this alloy is Fe Cr Ni Mn Iron — the balance, never listed by a standard — 76.1 % Cr — 16.5 % Ni — 4.8 % Mn — 1 % Traces & impurities · 1.6 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.06 | | Si | ≤ 0.8 | | Mn | ≤ 1 | | P | 0.035 | | S | 0.02 | | Cr | 15.5–17.5 | | Mo | ≤ 0.7 | | Ni | 4–5.5 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel 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 | ≤0,06 | — | 0.060 | Max | | Si | ≤0,80 | — | 0.800 | Max | | P | 0,035 | 0.035 | 0.035 | Exact | | S | 0,02 | 0.020 | 0.020 | Exact | | Cr | 15,5-17,5 | 15.500 | 17.500 | Range | | Mn | ≤1,00 | — | 1.000 | Max | | Ni | 4,00-5,50 | 4.000 | 5.500 | Range | | Mo | ≤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. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.4, a shared category, and a published range for Cr / Ni 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.
