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. ## Also known as 6 designations · 5 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Chemical composition 10 elements on file · weight % What this alloy is Fe Cr Ni Mn Iron — the balance, never listed by a standard — 84.8 % Cr — 12 % Ni — 1.2 % Mn — 0.7 % Traces & impurities · 1.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.1 | | Si | ≤ 0.4 | | Mn | 0.5–0.8 | | P | 0.03 | | S | 0.02 | | Cr | 11.5–12.5 | | Mo | ≤ 0.5 | | Ni | 0.8–1.5 | | V | ≤ 0.08 | | Cu | ≤ 0.3 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Vanadium 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 | ≤0,10 | — | 0.100 | Max | | Si | ≤0,40 | — | 0.400 | Max | | P | 0,03 | 0.030 | 0.030 | Exact | | S | 0,02 | 0.020 | 0.020 | Exact | | V | ≤0,08 | — | 0.080 | Max | | Cr | 11,5-12,5 | 11.500 | 12.500 | Range | | Mn | 0,50-0,80 | 0.500 | 0.800 | Range | | Ni | 0,80-1,50 | 0.800 | 1.500 | Range | | Cu | ≤0,30 | — | 0.300 | Max | | Mo | ≤0,50 | — | 0.500 | 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. ## Properties by condition 1 conditions · 5 values By heat-treated condition**no delivery state stated** source `splav` | Heat-treated condition | Rm N/mm² | Re N/mm² | A5% | Z% | KCU kJ/m² | |---|---|---|---|---|---| | Casting, GOST 977-88 | 589 | 491 | 15 | 30 | 294 | 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. ## 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.
