Sanfeng Brinell Rockwell Universal Hardness Tester

Sanfeng Brinell Rockwell Universal Hardness Tester

Part 1: Principle of Brinell Hardness Testing MethodThe Brinell hardness test was proposed by Swedish engineer J.A. Brinell in 1900 and is one of the earliest standardized hardness testing methods. Its principle is very classic and intuitive. Testing principle: Use a hard alloy ball with a certain diameter to press it into the surface of the specimen under the specified test force. After maintaining the specified holding time, remove the test force. Measure the diameter of the indentation left on the surface of the specimen. Hardness value calculation: The Brinell hardness value is calculated by dividing the test force by the surface area of the indentation. The formula is: HBW=0.102 × F/AF: Test force A: Indentation surface. In practical operation, due to the easier measurement of indentation diameter, the lookup table method is usually used to directly correspond the HBW value based on the test force F, indenter diameter D, and measured indentation diameter d. Representation method: For example: 250 HBW 10/3000250: Brinell hardness value HBW: represents the indenter as a hard alloy ball 10: indenter ball diameter 3000: test force Main characteristics: advantages: large indentation, stable data: due to the large indentation area, it can better reflect the average performance of the material over a large range, especially effective for materials with uneven microstructure. Reliable results: Good data repeatability and low dispersion. There is a good correspondence with tensile strength: for many steels, there is an approximate relationship: tensile strength ≈ K × HBW. Disadvantages: Large damage to the sample: large indentation, not suitable for finished product inspection or small or thin piece testing. The operation is relatively cumbersome: it requires measuring the indentation diameter, calculating or checking the table, which is less efficient than Rockwell hardness. Pressure head may deform: In the early days, steel balls were used to test hard materials, but now the standard specifies the use of hard alloy balls uniformly.
