The only composition figure recorded for it is Si 0.8–1.8%. We list one designation recorded for this grade, in the standard GOST. - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=0fa7621b-a2a4-4063-8dc9-4ad09358e1e8&designation=85e1d0f5-07f6-4199-b495-17821f0bf56a "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/1211.pdf "Datasheet as PDF") ## Also known as 2 designations · 1 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once. GOST Russia / CIS · 2 - **1211 This grade’s own name** - [Sv-12Kh11NMF Indicative](/materials/gost/sv-12kh11nmf "GOST Sv-12Kh11NMF") Every designation on file is listed — no truncation, no “+ n more”. Each one is itself a route that leads back here. ## Chemical composition 1 elements on file · weight % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | Si | 0.8–1.8 | Silicon 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 | |---|---|---|---|---| | Si | 0.8 - 1.8 | 0.800 | 1.800 | 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: C, Mn, 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.
