Rockwell Hardness Tests

Rockwell hardness: the most widely practiced hardness test that correlates to material strength.

ATS' Rockwell Hardness Test Capabilities

An indentation process, Rockwell Hardness testing is straightforward and uncomplicated in practice. Using a diamond cone or sphere-shaped indenter, a minor load is applied to a sample of the investigated material to remove any surface effects. Immediately following the minor load, a “major” load sets a force on the material for a specific amount of time, creating a deeper indentation. The calculation of the Rockwell hardness number takes the difference between both the minor and major load depths.

Since Rockwell Hardness testing can measure the hardness of many materials and hardness ranges, it is important that the correct Rockwell scale is defined for each case.
