Its recorded composition includes C ≤ 2.4%, Si 1.5–3%, Mn 0.5–1.5%, Ni 34–36% and Cu ≤ 0.5%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm 370–410 N/mm², Re 210–240 N/mm², A5 30% and HB 130–180. Further recorded physical values: E 126 GPa. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=1fb32d26-0d22-423b-8387-e318ca67fa9e&designation=c0f1e30e-f1d4-4bd1-ae69-5afaaf9c8dcd "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/s-ni35.pdf "Datasheet as PDF") ## Chemical composition 7 elements on file · weight % What this alloy is Fe Ni C Si Iron — the balance, never listed by a standard — 58.6 % Ni — 35 % C — 2.4 % Si — 2.3 % Traces & impurities · 1.8 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 2.4 — Unusual | | Si | 1.5–3 — Unusual | | Mn | 0.5–1.5 | | P | ≤ 0.08 — Unusual | | Cr | ≤ 0.2 | | Ni | 34–36 | | Cu | ≤ 0.5 | Carbon Silicon Manganese Phosphorus 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 2.4 | — | 2.400 | Max | | Si | 1.5 - 3 | 1.500 | 3.000 | Range | | P | max 0.08 | — | 0.080 | Max | | Cr | max 0.2 | — | 0.200 | Max | | Mn | 0.5 - 1.5 | 0.500 | 1.500 | Range | | Ni | 34 - 36 | 34.000 | 36.000 | 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. ## Properties by condition 2 conditions · 5 values By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | Re N/mm² | A5% | HB | |---|---|---|---|---| | Casting, GOST 7769-82 | 370 – 410 | 210 – 240 | 30 | — | | GOST 7769-82 | — | — | — | 130 – 180 | At temperature**no delivery state stated** source `splav` | Temperature °C | Elastic modulus GPa | |---|---| | 20 | 126 | 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. ## Looking for this grade under another name?
