GOST · Russia / CIS · 1 designation # L-NiMn13-7 L-NiMn13-7 is a grade designated under GOST. Its recorded composition includes C ≤ 3%, Si 1.5–3%, Mn 6–7%, Ni 12–14% and Cu ≤ 0.5%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=817e2a6e-f444-4a98-ab82-9401bddbec7d&designation=0582b35a-60f2-411b-afef-a63a962c88e0 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/l-nimn13-7.pdf "Datasheet as PDF") ## Chemical composition 6 elements on file · weight % What this alloy is Fe Ni Mn C Iron — the balance, never listed by a standard — 74.6 % Ni — 13 % Mn — 6.5 % C — 3 % Traces & impurities · 2.9 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 3 — Unusual | | Si | 1.5–3 — Unusual | | Mn | 6–7 — Unusual | | Cr | ≤ 0.2 | | Ni | 12–14 | | Cu | ≤ 0.5 | Carbon Silicon Manganese Chromium Nickel 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 | max 3 | — | 3.000 | Max | | Si | 1.5 - 3 | 1.500 | 3.000 | Range | | Cr | max 0.2 | — | 0.200 | Max | | Mn | 6 - 7 | 6.000 | 7.000 | Range | | Ni | 12 - 14 | 12.000 | 14.000 | Range | | Cu | max 0.5 | — | 0.500 | 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: Mo. ## Physical & mechanical properties 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. ## Looking for this grade under another name?
