They are used for load-bearing structures, vehicles and machinery where strength, durability and reduced material weight are important. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Chemical composition 9 elements on file · weight % What this alloy is Fe Mn Cr Si Iron — the balance, never listed by a standard — 95.3 % Mn — 1.5 % Cr — 1.3 % Si — 0.8 % Traces & impurities · 1.1 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.22 | | Si | ≤ 0.8 | | Mn | ≤ 1.5 | | P | 0.025 | | S | 0.012 | | Cr | ≤ 1.3 | | Mo | ≤ 0.5 | | Cu | ≤ 0.3 | | B | ≤ 0.005 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Copper Boron 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 | |---|---|---|---|---| | B | ≤0,005 | — | 0.005 | Max | | C | ≤0,22 | — | 0.220 | Max | | Si | ≤0,80 | — | 0.800 | Max | | P | 0,025 | 0.025 | 0.025 | Exact | | S | 0,012 | 0.012 | 0.012 | Exact | | Cr | ≤1,30 | — | 1.300 | Max | | Mn | ≤1,50 | — | 1.500 | Max | | Cu | ≤0,30 | — | 0.300 | Max | | Mo | ≤0,50 | — | 0.500 | 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: Ni. ## 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 1.8, a shared category, and a published range for Mn / Cr 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.
