They are used for components that require high strength and hardness together with useful toughness and dimensional stability. 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 Mn Si C Iron — the balance, never listed by a standard — 97.4 % Mn — 1.4 % Si — 0.7 % C — 0.4 % Traces & impurities · 0.2 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.35–0.4 | | Si | 0.5–0.8 | | Mn | 1.2–1.5 | | P | 0.035 | | S | 0.03–0.065 — Unusual | | V | 0.08–0.13 | Carbon Silicon Manganese Phosphorus Sulfur Vanadium 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 | 0,35-0,40 | 0.350 | 0.400 | Range | | Si | 0,50-0,80 | 0.500 | 0.800 | Range | | P | 0,035 | 0.035 | 0.035 | Exact | | S | 0,030-0,065 | 0.030 | 0.065 | Range | | V | 0,08-0,13 | 0.080 | 0.130 | Range | | Mn | 1,20-1,50 | 1.200 | 1.500 | 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: Ni, Cr, Mo. ## Physical & mechanical properties Density 7,67 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. ## Looking for this grade under another name?
