UNS · United States · 3 designations # G50986 G50986 is a designation in UNS for the material held under material number 1.3501, also listed as 100Cr2. It is a material in the category Bearing steels. We list 3 designations recorded for this grade, in the standards DIN / EN, UNS and AISI / SAE. - [*Material no.* **1.3501**](/materials/material-no/1.3501 "Material no.: 1.3501") - [*Category* **Bearing steels · 17 grades**](/categories/bearing-steels "Category: Bearing steels · 17 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=fa7f98a3-074a-4acd-b679-5990120da647&designation=26549d04-8603-4fa9-a1c1-3f251cf83928 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/uns/g50986.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 100Cr2 This grade’s own name](/materials/din-en/100cr2 "DIN / EN 100Cr2") - [AISI / SAE E50100 This grade’s own name](/materials/aisi-sae/e50100 "AISI / SAE E50100") ## 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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: 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. ## Looking for this grade under another name?
