Its recorded composition includes C 0.32–0.4%, Si 0.15–0.35%, S 0.08–0.15%, Mn 0.7–1% and Cu ≤ 0.25%. No cross-standard equivalents are recorded for this grade yet. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=69b0247a-b361-4e6e-9e0f-7c51de48e15b&designation=e982072b-60e0-4de2-acfd-3e09b7aa5181 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/a35.pdf "Datasheet as PDF") ## Chemical composition 6 elements on file · weight % What this alloy is Fe Mn C Si Iron — the balance, never listed by a standard — 98.1 % Mn — 0.9 % C — 0.4 % Si — 0.3 % Traces & impurities · 0.4 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.32–0.4 | | Si | 0.15–0.35 | | Mn | 0.7–1 | | P | ≤ 0.06 | | S | 0.08–0.15 — Unusual | | Cu | ≤ 0.25 | Carbon Silicon 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 | 0.32 - 0.4 | 0.320 | 0.400 | Range | | Si | 0.15 - 0.35 | 0.150 | 0.350 | Range | | P | max 0.06 | — | 0.060 | Max | | S | 0.08 - 0.15 | 0.080 | 0.150 | Range | | Mn | 0.7 - 1 | 0.700 | 1.000 | Range | | Cu | max 0.25 | — | 0.250 | 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: Ni, Cr, 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.
