The PHB-150 Pin Static Brinell Hardness Tester is designed following the Brinell hardness test method. The test force is controlled by a shear pin. After reading the diameter of the indention with the reading microscope, the Brinell hardness number can be obtained from the lookup table,and the work principle as below:
WORKING PRINCIPLE
According to the similarity principle of Brinell hardness testing, with testing force of 1580kg, indenter diameter of 7.26mm, then F/D2 =30. The test condition of the HB tester is equivalent to the standard Brinell hardness test with 3000kgf and 10mm ball indenter.
