Material number · Europe · 3 designations # 1.3536 1.3536 is the material number of the grade also listed as 100CrMo7-3. It is a material in the category Bearing steels. We list 3 designations recorded for this grade, in the standards DIN / EN, UNS and ČSN. - ***Material no.* **1.3536**** - [*Category* **Bearing steels · 17 grades**](/categories/bearing-steels "Category: Bearing steels · 17 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=12a18e4b-a494-414c-bb7b-780a89cd6df2 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.3536.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 100CrMo7-3 This grade’s own name](/materials/din-en/100crmo7-3 "DIN / EN 100CrMo7-3") - [UNS K19965 This grade’s own name · 2 grades on that route](/materials/uns/k19965 "UNS K19965") ## About Bearing steels Bearing steels are high-carbon steels designed for rolling-element bearings and other components exposed to repeated contact loading. They are characterised by high hardness, wear resistance and resistance to rolling-contact fatigue after suitable heat treatment. They are used for bearing rings, races and rolling elements where reliable operation under cyclic loads is required. 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

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 7,85 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 1.3, a shared category, and a published range for Cr / Mn 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.
