Recorded mechanical properties include Rm 490–686 N/mm² and HB 179–187; these figures vary with the delivery condition and dimension. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.1160**](/materials/material-no/1.1160 "Material no.: 1.1160") - [*Category* **Low-temperature structural steels · 55 grades**](/categories/low-temperature-structural-steels "Category: Low-temperature structural steels · 55 grades") - *Designations* **14** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=03a918c5-27c1-4440-95d4-2f7c27dbad04&designation=2c847852-b472-4b55-83bc-4d6313dae97a "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/22mn6.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [UNS G15240 This grade’s own name · 2 grades on that route](/materials/uns/g15240 "UNS G15240") - [AISI / SAE 1524 This grade’s own name · 2 grades on that route](/materials/aisi-sae/1524 "AISI / SAE 1524") ## 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 14 designations · 7 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 Si C Iron — the balance, never listed by a standard — 98 % Mn — 1.5 % Si — 0.2 % 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 | 0.18–0.25 | | Si | 0.15–0.3 | | Mn | 1.3–1.7 — Unusual | | P | 0.035 | | S | 0.035 | 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 | 0,18-0,25 | 0.180 | 0.250 | Range | | Si | 0,15-0,30 | 0.150 | 0.300 | Range | | P | 0,035 | 0.035 | 0.035 | Exact | | S | 0,035 | 0.035 | 0.035 | Exact | | Mn | 1,30-1,70 | 1.300 | 1.700 | 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: 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 · 3 values By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | HB | |---|---|---| | Steel cold-drawn , GOST 10702-78 | 490 – 686 | — | | (hot-rolled, annealing) | — | 187 | | Bar GOST 10702-78 | — | 179 | 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 1.1, 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.
