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.

Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Physical & mechanical properties
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.
