GB/T 231.4-2009 is the standard of Hardness value table for brinell hardness test of metal materials. It systematically sorts out the corresponding brinell hardness value according to different test forces and indentation diameters. In the production, processing and mass inspection of metal materials, the staff can quickly and accurately obtain the brinell hardness of materials through measurement indentation data. The table provides key data support for evaluating the performance of metal materials, guarantees the conformity and accuracy of brinell hardness test results in different scenarios, and promotes the standardization of the metal industry.
