Product Description

The HBC Hammering Brinell hardness tester uses a steel ball of a certain diameter and, after applying an instantaneous impact, causes the steel ball to sink into the test piece and the standard hardness test block, thus obtaining an indentation, and by simple measurement of the indentation and checking the table the Brinell hardness value of the test piece can be quickly obtained. It can be used to determine the Brinell hardness of ferrous and non-ferrous metals. Suitable for use in factory and mine workshops and material storage sites.
