Its recorded density is 7.71 g/cm³. - [*Material no.* **1.1219**](/materials/material-no/1.1219 "Material no.: 1.1219") - [*Category* **Unalloyed bearing steels · 1 grades**](/categories/unalloyed-bearing-steels "Category: Unalloyed bearing steels · 1 grades") - *Designations* **5** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=ca2da26c-b4b8-4f86-84fd-6ef9fef01f48&designation=1640f756-5ade-49fa-bdaa-97328b81e198 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/c56e2.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [JIS S55C This grade’s own name · 3 grades on that route](/materials/jis/s55c "JIS S55C") ## About Unalloyed bearing steels Rolling bearing steels are characterized by a high degree of hardness, service life, wear resistance and dimensional stability. Due to these good properties, these alloys are used for components subject to wear in mechanical engineering and in the automotive industry. They find their use e.g. B. as ball, roller and needle bearings and in wear-stressed components such as pump shafts. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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: Cr. ## Physical & mechanical properties Density 7,71 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. ## Looking for this grade under another name?
