Material number · Europe · 12 designations # 1.7361 1.7361 is the material number of the grade also listed as 32CrMo12. It is a material in the category Quenched and tempered steels. We list 12 designations recorded for this grade, in the standards DIN / EN, BS, AFNOR, UNE, UNI, SS, ČSN and PN. - ***Material no.* **1.7361**** - [*Category* **Quenched and tempered steels · 133 grades**](/categories/quenched-and-tempered-steels "Category: Quenched and tempered steels · 133 grades") - *Designations* **12** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c34832c4-64b9-4b78-8c40-c78d64a14ba8 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.7361.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 32CrMo12 This grade’s own name](/materials/din-en/32crmo12 "DIN / EN 32CrMo12") ## About Quenched and tempered steels Quenched and tempered steels are heat-treated steels designed to combine high strength with useful toughness and ductility. They are used for heavily loaded components such as shafts, gears, fasteners and structural machine parts where resistance to mechanical stress is required. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 12 designations · 8 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 8 elements on file · weight % What this alloy is Fe Cr Ni Mn Iron — the balance, never listed by a standard — 94.6 % Cr — 3.1 % Ni — 0.6 % Mn — 0.6 % Traces & impurities · 1.2 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.28–0.35 | | Si | ≤ 0.4 | | Mn | 0.4–0.7 | | P | 0.035 | | S | 0.035 | | Cr | 2.8–3.3 — Unusual | | Mo | 0.3–0.5 | | Ni | 0.6 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel 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 | 0,28-0,35 | 0.280 | 0.350 | Range | | Si | ≤0,40 | — | 0.400 | Max | | P | 0,035 | 0.035 | 0.035 | Exact | | S | 0,035 | 0.035 | 0.035 | Exact | | Cr | 2,80-3,30 | 2.800 | 3.300 | Range | | Mn | 0,40-0,70 | 0.400 | 0.700 | Range | | Ni | 0,6 | 0.600 | 0.600 | Exact | | Mo | 0,30-0,50 | 0.300 | 0.500 | 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 computed from composition · °C Predicted Ae3 784 °C Predicted Ae1 790 °C Predicted Acm 622 °C Predicted Bs 451 °C These four temperatures are a CALCULATION from this grade's own composition, using the published Li, Niebuhr, Meekisho & Atteridge (1998) model — never a measurement, and computed from the UPPER BOUND of each element's specified range, not a mid-range figure. Where this grade also has a measured transformation point (Ac1, Ac3, Ar1, Ar3) on file, it is shown separately, in Physical & mechanical properties, and is never replaced by the predicted figures here — Ae (predicted, equilibrium) and Ac/Ar (measured, on heating or cooling) are different physical quantities and can differ by tens of degrees; a mismatch between the two is not an error in either. ## 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 1 conditions · 6 values By thickness**Quenched and tempered** source `steelnumber` | Thickness mm | Rm N/mm² | A% | |---|---|---| | ≤ 160 | 900 | 12 | | 160 – 330 | 850 | 13 | | 330 – 660 | 700 | 15 | 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?
