DIN / EN · Europe · 2 designations # C2E C2E is a material in the category Others, held under material number 1.1004. Its recorded composition includes C ≤ 0.04%, Al 0.05–0.15%, P 0.035%, S 0.035% and Mn ≤ 0.2%. We list one designation recorded for this grade, in the standard DIN / EN. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.1004**](/materials/material-no/1.1004 "Material no.: 1.1004") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=222674f1-779f-472f-a1a2-112375a4c6f6&designation=6c545eda-19a2-4f0a-abe5-d47bea5692c6 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/c2e.pdf "Datasheet as PDF") ## About Others These are miscellaneous metallic alloys that do not fit a more specific material family and may be based on iron, nickel, cobalt, copper or other alloy systems. They are selected for applications requiring particular combinations of strength, hardness, toughness, wear resistance or resistance to demanding service conditions. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 2 designations · 1 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once. DIN / EN Europe · 2 - **C2E This grade’s own name** - [Mk 3 This grade’s own name Withdrawn](/materials/din-en/mk-3 "DIN / EN Mk 3") Every designation on file is listed — no truncation, no “+ n more”. Each one is itself a route that leads back here. ## Chemical composition 6 elements on file · weight % What this alloy is Fe Mn Al C Iron — the balance, never listed by a standard — 99.6 % Mn — 0.2 % Al — 0.1 % C — 0 % Traces & impurities · 0.1 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.04 | | Si | Trace | | Mn | ≤ 0.2 | | P | 0.035 | | S | 0.035 | | Al | 0.05–0.15 | Carbon Silicon Manganese Phosphorus Sulfur Aluminium 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 | ≤0,04 | — | 0.040 | Max | | Al | 0,05-0,15 | 0.050 | 0.150 | Range | | Si | Spuren/Traces | — | — | Trace | | P | 0,035 | 0.035 | 0.035 | Exact | | S | 0,035 | 0.035 | 0.035 | Exact | | Mn | ≤0,20 | — | 0.200 | 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: Si, 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 1.1, a shared category, and a published range for Al / Mn 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.
