MSZ · Hungary · 11 designations # Fe 275 D Fe 275 D is a designation in MSZ for the material held under material number 1.0145, also listed as S275J2. It is a material in the category Unalloyed structural steels. We list 11 designations recorded for this grade, in the standards DIN / EN, ASTM, BS, GB, SS, ČSN, STN, MSZ and NBN. - [*Material no.* **1.0145**](/materials/material-no/1.0145 "Material no.: 1.0145") - [*Category* **Unalloyed structural steels · 452 grades**](/categories/unalloyed-structural-steels "Category: Unalloyed structural steels · 452 grades") - *Designations* **11** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c7536c89-a762-495b-a8fd-033d7772f7c7&designation=01ce2ac4-53d7-4bd5-ad7d-2d5c3555db32 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/msz/fe-275-d.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN S275J2 This grade’s own name · 2 grades on that route](/materials/din-en/s275j2 "DIN / EN S275J2") - [ASTM A1011SS Grade40 This grade’s own name](/materials/astm/a1011ss-grade40 "ASTM A1011SS Grade40") ## About Unalloyed structural steels Unalloyed structural steels include all low-carbon steels in which the iron companions do not exceed specified minimum values. The yield strength, formability and weldability are the decisive factors for their use. They are soft, pliable, tough and stretchy, but cannot be hardened by heat treatment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 11 designations · 9 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Chemical composition 5 elements on file · weight % What this alloy is Fe Mn Cu C Iron — the balance, never listed by a standard — 97.7 % Mn — 1.5 % Cu — 0.6 % C — 0.2 % Traces & impurities · 0 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.18 | | Mn | ≤ 1.5 | | P | 0.025 | | S | 0.025 | | Cu | ≤ 0.55 | Carbon Manganese Phosphorus Sulfur Copper 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 | — | 0.180 | Max | | P | 0,025 | 0.025 | 0.025 | Exact | | S | 0,025 | 0.025 | 0.025 | Exact | | Mn | ≤1,50 | — | 1.500 | Max | | Cu | ≤0,55 | — | 0.550 | 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 1.0, a shared category, and a published range for Mn / Cu 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.
