WebApr 12, 2024 · Rockwell hardness (HR) When HB>450 or the sample is too small, the Brinell hardness test cannot be used instead of Rockwell hardness measurement. It is to press a diamond cone with a top angle of 120 ° or a steel ball with a diameter of 1.59 and 3.18 mm into the surface of the tested material under a certain load, and calculate the hardness of ... WebThe Brinell method principle involves measuring the hardness of a material when an indenter is compressed into a test piece under a specified load. To measure the depth, the test piece is placed on a flat surface, and then a specified load is applied by an indenter to make an indent on the test piece. The depth of the indent is measured using ...
