1. hammering Brinell hardness Brinell hardness test principle, the large-diameter ball indenter into the surface of the sample, the larger the area of the test, the test is suitable for relatively coarse grain Forging.
2. Impact hardness test Brinell hardness test hammer belongs, ball indentation instantaneous, not as standard as Brinell hardness test, the test force dwell time of several seconds, allowing the metal indentation at achieving full plastic deformation, so that test accuracy hammering Brinell hardness Brinell hardness lower than desktop meter.
3. hammering Brinell hardness despite the impact of lower precision hardness test method belongs, but it belongs in a variety of hardness test methods Brinell hardness test with higher accuracy compared with other impact hardness test ( For example: Shore hardness, Leeb hardness tester). Factors on the test results is relatively small, the test results more stable, more reliable test value.
4. hammering Brinell hardness Brinell hardness with the same desktop, leave a test can be repeated at any time Brinell hardness indentation on the workpiece after the test, the test results when there is doubt or disagreement both supply and demand when can test Brinell again. This is better than in the hardness.
