The most-used names for this grade.About Boron-alloyed case hardening steels
Boron-alloyed case hardening steels are low-carbon alloy steels designed to develop a hard surface with a tougher core after case hardening. Their boron addition improves hardenability, while the alloying composition supports the production of durable gears, shafts and other wear-prone components.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Chemical composition

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.
