While hardness testing does not provide a direct assessment of product or raw material performance qualities, hardness correlates directly to qualities like strength and wear resistance. Hardness ...

Rockwell hardness testing is a method of determining the relative hardness of a material. In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a ...

When designing metal parts, it's important to specify their hardness. However, many engineers have only a shaky understanding of what hardness actually is, or how it's measured. There are good reasons ...
