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 9 elements on file · weight % What this alloy is Fe Ni Cr Cu Iron — the balance, never listed by a standard — 40.6 % Ni — 28.8 % Cr — 20.5 % Cu — 3.5 % Traces & impurities · 6.6 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.07 | | Si | ≤ 2 | | Mn | ≤ 2 | | P | ≤ 0.04 | | S | ≤ 0.04 | | Cr | 19–22 | | Mo | 2–3 | | Ni | 27.5–30 — Unusual | | Cu | 3–4 — Unusual | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Copper 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 | max 0.07 | — | 0.070 | Max | | Si | max 2 | — | 2.000 | Max | | P | max 0.04 | — | 0.040 | Max | | S | max 0.04 | — | 0.040 | Max | | Cr | 19 - 22 | 19.000 | 22.000 | Range | | Mn | max 2 | — | 2.000 | Max | | Ni | 27.5 - 30 | 27.500 | 30.000 | Range | | Cu | 3 - 4 | 3.000 | 4.000 | Range | | Mo | 2 - 3 | 2.000 | 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 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. ## Properties by condition 1 conditions · 4 values By delivery state**no delivery state stated** source `steeljis` | Delivery state | Rm N/mm² | Re N/mm² | A% | HB | |---|---|---|---|---| | Casting | 390 | 165 | 30 | — | | Solution heat treatment | — | — | — | 183 | Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Looking for this grade under another name?
