Their machinability makes them suitable for turned, drilled and threaded components produced in high volumes, including small precision parts and fasteners. 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 Pb Iron — the balance, never listed by a standard — 98.3 % Mn — 0.7 % Si — 0.3 % Pb — 0.2 % Traces & impurities · 0.5 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.18–0.25 | | Si | 0.1–0.4 | | Mn | 0.5–0.9 | | P | 0.07 | | S | 0.15–0.25 | | Pb | 0.15–0.3 | Carbon Silicon Manganese Phosphorus Sulfur Lead 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 | 0,18-0,25 | 0.180 | 0.250 | Range | | Si | 0,10-0,40 | 0.100 | 0.400 | Range | | P | 0,07 | 0.070 | 0.070 | Exact | | S | 0,15-0,25 | 0.150 | 0.250 | Range | | Mn | 0,50-0,90 | 0.500 | 0.900 | Range | | Pb | 0,15-0,30 | 0.150 | 0.300 | 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 7,85 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 1.0, a shared category, and a published range for Mn / Si 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.
