Material number · Europe · 1 designation # 1.5613 1.5613 is the material number of the grade also listed as 24Ni4. It is a material in the category Low-temperature structural steels. We list 1 designations recorded for this grade, in the standards DIN / EN. - ***Material no.* **1.5613**** - [*Category* **Low-temperature structural steels · 55 grades**](/categories/low-temperature-structural-steels "Category: Low-temperature structural steels · 55 grades") - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=956cd601-ca22-419e-a686-17d466a7ba0e "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.5613.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 24Ni4 This grade’s own name](/materials/din-en/24ni4 "DIN / EN 24Ni4") ## About Low-temperature structural steels Low-temperature structural steels are structural steels designed to retain toughness and reliable load-bearing performance in cold service. Their resistance to brittle fracture at low temperatures makes them suitable for structures, pressure-containing equipment and other components exposed to severe cold. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 1 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 · 1 - [24Ni4 This grade’s own name](/materials/din-en/24ni4 "DIN / EN 24Ni4") Every designation on file is listed — no truncation, no “+ n more”. Each one is itself a route that leads back here. ## Chemical composition 7 elements on file · weight % What this alloy is Fe Ni Mn Cr Iron — the balance, never listed by a standard — 97.3 % Ni — 1.2 % Mn — 0.7 % Cr — 0.3 % Traces & impurities · 0.6 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.2–0.28 | | Si | 0.15–0.35 | | Mn | 0.6–0.8 | | P | 0.035 | | S | 0.035 | | Cr | ≤ 0.3 | | Ni | 1–1.3 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Nickel 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 | 0,20-0,28 | 0.200 | 0.280 | Range | | Si | 0,15-0,35 | 0.150 | 0.350 | Range | | P | 0,035 | 0.035 | 0.035 | Exact | | S | 0,035 | 0.035 | 0.035 | Exact | | Cr | ≤0,30 | — | 0.300 | Max | | Mn | 0,60-0,80 | 0.600 | 0.800 | Range | | Ni | 1,00-1,30 | 1.000 | 1.300 | 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: 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 1.5, a shared category, and a published range for Ni / 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.
