UNI · Italy · 3 designations # CF35SMnPb10 CF35SMnPb10 is a designation in UNI for the material held under material number 1.0765, also listed as 36 SMnPb 14. It is a material in the category Free cutting steels. We list 3 designations recorded for this grade, in the standards DIN / EN, GOST and UNI. - [*Material no.* **1.0765**](/materials/material-no/1.0765 "Material no.: 1.0765") - [*Category* **Free cutting steels · 49 grades**](/categories/free-cutting-steels "Category: Free cutting steels · 49 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=5eeea601-e9ea-4483-b022-e24f524526d6&designation=e1c93954-3414-4d8a-8450-bd38d1c31e3d "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/uni/cf35smnpb10.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 36 SMnPb 14 This grade’s own name](/materials/din-en/36-smnpb-14 "DIN / EN 36 SMnPb 14") ## About Free cutting steels Free-cutting steels are steels formulated to machine readily and produce manageable chips during cutting. Their machinability makes them suitable for turned, drilled and threaded components produced in high volumes, including small precision parts and fasteners. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 3 designations · 3 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Chemical composition 6 elements on file · weight % What this alloy is Fe Mn Si C Iron — the balance, never listed by a standard — 97.3 % Mn — 1.5 % Si — 0.4 % C — 0.4 % Traces & impurities · 0.5 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.32–0.39 | | Si | ≤ 0.4 | | Mn | 1.3–1.7 | | P | 0.06 | | S | 0.1–0.18 | | Pb | 0.15–0.35 | Carbon Silicon Manganese Phosphorus Sulfur Lead 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 | 0,32-0,39 | 0.320 | 0.390 | Range | | Si | ≤0,40 | — | 0.400 | Max | | P | 0,06 | 0.060 | 0.060 | Exact | | S | 0,10-0,18 | 0.100 | 0.180 | Range | | Mn | 1,30-1,70 | 1.300 | 1.700 | Range | | Pb | 0,15-0,35 | 0.150 | 0.350 | 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: Ni, Cr, Mo. ## Physical & mechanical properties Density 7,85 g/cm³ Exact 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 · 11 values By thickness**Cold drawn / hard** source `steelnumber` | Thickness mm | Rm N/mm² | A% | |---|---|---| | 5 – 10 | 660 – 960 | 6 | | 10 – 16 | 620 – 920 | 6 | | 16 – 40 | 600 – 900 | 7 | | 40 – 63 | 580 – 840 | 8 | | 63 – 100 | 560 – 820 | 9 | By delivery state**As rolled and turned** source `steelnumber` | Delivery state | HB | |---|---| | As rolled and turned | 163 – 222 | 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. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.0, a shared category, and a published range for Mn / Pb that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
