Rockwell Hardness Guide What it is, How to Measure, More

The Rockwell hardness number is not the same as the calculated depth differential measurement. Softer metals allow for deeper penetration than harder metals, so the B A value will always be higher on soft metal test subjects than hard metals. The Rockwell hardness scale number appears inverse to the depth differential calculation.
