They combine the ductility needed for substantial plastic deformation with the strength and toughness required in cold-formed fasteners, automotive parts and other precision components. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Chemical composition 8 elements on file · weight % What this alloy is Fe Ni Mn Cr Iron — the balance, never listed by a standard — 96.1 % Ni — 2.3 % Mn — 0.5 % Cr — 0.4 % Traces & impurities · 0.8 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.12–0.18 | | Si | 0.15–0.35 | | Mn | 0.35–0.65 | | P | ≤ 0.03 | | S | ≤ 0.03 | | Cr | 0.2–0.5 | | Ni | 2–2.5 | | Cu | ≤ 0.3 | Carbon Silicon Manganese Phosphorus Sulfur Chromium 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 | 0.12 - 0.18 | 0.120 | 0.180 | Range | | Si | 0.15 - 0.35 | 0.150 | 0.350 | Range | | P | max 0.03 | — | 0.030 | Max | | S | max 0.03 | — | 0.030 | Max | | Cr | 0.2 - 0.5 | 0.200 | 0.500 | Range | | Mn | 0.35 - 0.65 | 0.350 | 0.650 | Range | | Ni | 2 - 2.5 | 2.000 | 2.500 | Range | | Cu | max 0.3 | — | 0.300 | 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: 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? Search the catalogue by designation, material number or composition — every name on this page is itself a way in.
