BS · United Kingdom · 14 designations # 3S132D 3S132D is a designation in BS for the material held under material number 1.8523, also listed as 39CrMoV13-9. It is a material in the category Nitriding steels. We list 14 designations recorded for this grade, in the standards DIN / EN, Standard not established, BS and UNI. - [*Material no.* **1.8523**](/materials/material-no/1.8523 "Material no.: 1.8523") - [*Category* **Nitriding steels · 11 grades**](/categories/nitriding-steels "Category: Nitriding steels · 11 grades") - *Designations* **14** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=05fca23d-e4dd-447f-a217-fd47a56de144&designation=1850f310-43da-4335-9e01-a22750cd030f "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/bs/3s132d.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 40CrMoV13-9 This grade’s own name](/materials/din-en/40crmov13-9 "DIN / EN 40CrMoV13-9") - [BS 3S132 This grade’s own name](/materials/bs/3s132 "BS 3S132") ## About Nitriding steels Nitriding steels are alloy steels designed for nitriding, a surface-hardening treatment that produces a hard, wear-resistant surface while retaining a tough supporting core. They are used for gears, shafts, dies and other components requiring resistance to wear, repeated loading and dimensional change in service. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 14 designations · 4 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

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. ## Physical & mechanical properties Density 7,72 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 · 9 values By thickness**Quenched and tempered** source `steelnumber` | Thickness mm | Rm N/mm² | A% | |---|---|---| | 16 – 40 | 950 – 1150 | 11 | | 40 – 100 | 900 – 1100 | 13 | | 100 – 160 | 870 – 1070 | 14 | | 160 – 250 | 800 – 1000 | 15 | By delivery state**Soft annealed** source `steelnumber` | Delivery state | HB | |---|---| | Soft annealed | 248 | 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?
