The provisions of Brinell hardness testing method on the test force are generally 3000kgf, so the indentation is large, the hardness value is slightly affected by the microstructure segregation and uneven composition of the sample, the dispersion of the test results is small, the reproducibility is good, and can objectively reflect the objective hardness of the material. Therefore, Brinell testing method has become one of the most extensive and commonly used hardness testing methods.
At present, the Brinell hardness tester are generally of a certain brand in the United States and PHB-3000 made by our company. However, the force application methods of these two hydraulic Brinell hardness testers are equivalent to the requirements of maintaining the test force for 10s specified in ASTM E10 standard method for Brinell hardness of metallic materials Part 1: Test methods by repeatedly loading 3000kgf test force for 3 ~ 4 times.
Our new product PHB-3000E electric portable Brinell hardness tester solves the problem of maintaining 3000kgf test force. It can balance 3000kgf test force for 10s in the testing process. The test method is fully in line with rather than equivalent to ASTM E10. Moreover, this product adopts electric force adding and automatically maintains the test force. The time can be completed with one key: test force loading - test force holding - obtain Brinell indentation, which is accurate and time-saving, It is labor-saving and suitable for on-site Brinell hardness testing of steel, non-ferrous metals, castings, forgings and semi-finished heat-treated parts. The obtained Brinell indentation can be directly read by the Brinell indentation automatic measurement system.
