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 6 elements on file · weight % What this alloy is Fe Ni Mn Si Iron — the balance, never listed by a standard — 89.7 % Ni — 9 % Mn — 0.9 % Si — 0.2 % Traces & impurities · 0.2 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.13 | | Si | 0.1–0.35 | | Mn | ≤ 0.9 | | P | ≤ 0.03 | | S | ≤ 0.03 | | Ni | 8.5–9.5 | Carbon Silicon Manganese Phosphorus Sulfur 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 | max 0.13 | — | 0.130 | Max | | Si | 0.1 - 0.35 | 0.100 | 0.350 | Range | | P | max 0.03 | — | 0.030 | Max | | S | max 0.03 | — | 0.030 | Max | | Mn | max 0.9 | — | 0.900 | Max | | Ni | 8.5 - 9.5 | 8.500 | 9.500 | 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 Not enough recorded composition to predict a transformation temperature for this grade — missing: Cr, Mo. ## 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. ## Looking for this grade under another name?
