How does the detection error of the indentation diameter of the Brinell Hardness Tester affect the hardness value? This article mainly introduces the impact on the hardness value from the measurement of the indentation diameter of the Hardness Tester, the precision of the microscope, and the three-point error of the reading of the personnel. The principle of its detection is that a steel ball with a certain diameter D is pressed into the surface of the metal to be tested under a certain load P, and the load is removed after a certain period of time. The Brinell hardness value is represented by the average pressure on the surface.
