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 6 elements on file · weight % What this alloy is Fe Cr Si Mn Iron — the balance, never listed by a standard — 67.7 % Cr — 28.5 % Si — 2 % Mn — 1 % Traces & impurities · 0.8 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.5–0.9 — Unusual | | Si | ≤ 2 | | Mn | ≤ 1 | | P | 0.045 | | S | 0.03 | | Cr | 27–30 — Unusual | Carbon Silicon Manganese Phosphorus Sulfur Chromium 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 | 0,50-0,90 | 0.500 | 0.900 | Range | | Si | ≤2,00 | — | 2.000 | Max | | P | 0,045 | 0.045 | 0.045 | Exact | | S | 0,03 | 0.030 | 0.030 | Exact | | Cr | 27,0-30,0 | 27.000 | 30.000 | Range | | Mn | ≤1,00 | — | 1.000 | 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 Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni, Mo. ## 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 / Si 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.
