DIN / EN · Europe · 5 designations # 15 S 22 15 S 22 is a designation in DIN / EN for the material held under material number 1.0723, also listed as 15 S 20. It is a material in the category Free cutting steels. We list 5 designations recorded for this grade, in the standards DIN / EN, BS, UNE and SS. - [*Material no.* **1.0723**](/materials/material-no/1.0723 "Material no.: 1.0723") - [*Category* **Free cutting steels · 49 grades**](/categories/free-cutting-steels "Category: Free cutting steels · 49 grades") - *Designations* **5** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=2fdab7f3-71d3-423a-ae76-87bf409a567f&designation=717bf39d-e44b-47da-9a13-ccbe9ca94470 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/15-s-22.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 15 S 20 This grade’s own name](/materials/din-en/15-s-20 "DIN / EN 15 S 20") ## 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 5 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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, 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. ## 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 / Si 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.
