HBE-3000A ELECTRONIC BRINELL HARDNESS TESTER - 1

UnitedTest BEIJING UNITED TEST CO.,LTD. Brinell Hardness Tester Model: reflect the comprehensive features of the material ,and the test i imposit microscopic segregation and the compositional unevenness of the s testing with high precision. Principle: All Brinell tests use a carbide ball indenter. The test procedure is as follows: ss tests is able to anization ence it is a hardness The indenter is pressed into the sample by an accurately controlled test force. The force is maintained for a specific dwell time, normally 10-15 seconds. After the dwell time is complete, the indenter is removed leaving a round indent in the sample. The size of the indent is determined optically by measuring two diagonals of the round indent using either a portable microscope or one that is integrated with the load application device. • The Brinell hardness number is a function of the test force divided by the curved surface area of the indent. The indentation is considered to be spherical with a radius equal to half the diameter of the ball. The average of the two diagonals is used in the following formula to calculate the Brinell hardness.
