Using a carbide ball penetrator, and applying loads of up to 3.000 kgf, Brinell hardness tester following ASTM E-10 is widely used on castings and forgings. This method requires optical reading of the diameter of ball indentation and using a chart to convert the average measurement to Brinell hardness value. We offer low-cost handheld Brinell scopes as well as a popular line of Automatic Brinell Microscopes for a high frequency of testing. Qualitest also offers Automatic In-line hardness testers for high volume testing.
