Their resistance to brittle fracture at low temperatures makes them suitable for structures, pressure-containing equipment and other components exposed to severe cold. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Chemical composition 10 elements on file · weight % What this alloy is Fe Ni Mn Si Iron — the balance, never listed by a standard — 95.3 % Ni — 2.5 % Mn — 0.7 % Si — 0.6 % Traces & impurities · 1 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.06–0.12 | | Si | ≤ 0.6 | | Mn | 0.5–0.8 | | P | 0.02 | | S | 0.015 | | Cr | ≤ 0.3 | | Mo | ≤ 0.2 | | Ni | 2–3 | | V | ≤ 0.05 | | 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 | 0,06-0,12 | 0.060 | 0.120 | Range | | Si | ≤0,60 | — | 0.600 | Max | | P | 0,02 | 0.020 | 0.020 | Exact | | S | 0,015 | 0.015 | 0.015 | Exact | | V | ≤0,05 | — | 0.050 | Max | | Cr | ≤0,30 | — | 0.300 | Max | | Mn | 0,50-0,80 | 0.500 | 0.800 | Range | | Ni | 2,00-3,00 | 2.000 | 3.000 | Range | | Cu | ≤0,30 | — | 0.300 | Max | | Mo | ≤0,20 | — | 0.200 | 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 computed from composition · °C Predicted Ae3 795 °C Predicted Ae1 689 °C Predicted Acm 354 °C Predicted Bs 539 °C These four temperatures are a CALCULATION from this grade's own composition, using the published Li, Niebuhr, Meekisho & Atteridge (1998) model — never a measurement, and computed from the UPPER BOUND of each element's specified range, not a mid-range figure. Where this grade also has a measured transformation point (Ac1, Ac3, Ar1, Ar3) on file, it is shown separately, in Physical & mechanical properties, and is never replaced by the predicted figures here — Ae (predicted, equilibrium) and Ac/Ar (measured, on heating or cooling) are different physical quantities and can differ by tens of degrees; a mismatch between the two is not an error in either. ## 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 1.5, a shared category, and a published range for Ni / Mn 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.
