DIN / EN · Europe · 1 designation # S355K2H S355K2H is a material in the category Others, held under material number 1.0512. Its recorded composition includes C ≤ 0.22%, Si ≤ 0.55%, P 0.03%, S 0.03% and Mn ≤ 1.6%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm 450–680 N/mm², ReH 295–355 N/mm² and A 18–22%; these figures vary with the delivery condition and dimension. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.0512**](/materials/material-no/1.0512 "Material no.: 1.0512") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=3a314148-a157-415f-a654-82ff9952f12d&designation=222c2396-a86b-4624-bdf3-4063caff1cc7 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/s355k2h.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. ## Chemical composition 5 elements on file · weight % What this alloy is Fe Mn Si C Iron — the balance, never listed by a standard — 97.6 % Mn — 1.6 % Si — 0.6 % C — 0.2 % Traces & impurities · 0.1 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.22 | | Si | ≤ 0.55 | | Mn | ≤ 1.6 | | P | 0.03 | | S | 0.03 | Carbon Silicon Manganese Phosphorus Sulfur 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 | ≤0,22 | — | 0.220 | Max | | Si | ≤0,55 | — | 0.550 | Max | | P | 0,03 | 0.030 | 0.030 | Exact | | S | 0,03 | 0.030 | 0.030 | Exact | | Mn | ≤1,60 | — | 1.600 | 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, 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. ## Properties by condition 1 conditions · 13 values By thickness**no delivery state stated** source `steelnumber` | Thickness mm | ReH N/mm² | Rm N/mm² | A% | |---|---|---|---| | ≤ 3 | — | 510 – 680 | — | | 3 – 100 | — | 470 – 630 | — | | ≤ 16 | 355 | — | — | | 16 – 40 | 345 | — | — | | 40 – 63 | 335 | — | 21 | | ≤ 40 | — | — | 22 | | 63 – 80 | 325 | — | — | | 63 – 100 | — | — | 20 | | 80 – 100 | 315 | — | — | | 100 – 120 | 295 | 450 – 600 | 18 | Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## 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.
