The most-used names for this grade.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.

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.
