Its recorded composition includes C ≤ 0.12%, Si 0.2–0.55%, Cr ≤ 0.3%, Mn 0.8–1.2% and Ni ≤ 0.3%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=94d804d2-77a7-45a0-9d31-15e98f3ddd3f&designation=c55ea315-b88b-4d09-b92c-54a58d8549c0 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/09mnv.pdf "Datasheet as PDF") ## Chemical composition 9 elements on file · weight % What this alloy is Fe Mn Si Cr Iron — the balance, never listed by a standard — 97.4 % Mn — 1 % Si — 0.4 % Cr — 0.3 % Traces & impurities · 0.9 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.12 | | Si | 0.2–0.55 | | Mn | 0.8–1.2 | | P | ≤ 0.045 | | S | ≤ 0.045 | | Cr | ≤ 0.3 | | Ni | ≤ 0.3 | | V | 0.04–0.12 | | Cu | ≤ 0.3 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Nickel Vanadium 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 | ≤0.12 | — | 0.120 | Max | | Si | 0.2-0.55 | 0.200 | 0.550 | Range | | P | ≤0.045 | — | 0.045 | Max | | S | ≤0.045 | — | 0.045 | Max | | V | 0.04-0.12 | 0.040 | 0.120 | Range | | Cr | ≤0.3 | — | 0.300 | Max | | Mn | 0.8-1.2 | 0.800 | 1.200 | Range | | Ni | ≤0.3 | — | 0.300 | Max | | Cu | ≤0.3 | — | 0.300 | 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? Search the catalogue by designation, material number or composition — every name on this page is itself a way in.
