GB/T 230.1-2018 specifies the test method for rockwell hardness of metal materials. It specifies the test principle and is suitable for a variety of metal materials. It sets strict requirements on the accuracy and indenter size of the Rockwell hardness tester, and details the preparation specifications of the sample, such as size and surface roughness. The standard also specifies the test operation process, including the steps of applying, holding and removing the test force, as well as the measurement and calculation methods of the Hardness value. According to this standard, the metal rockwell hardness can be accurately determined, providing a reliable basis for the quality control and performance evaluation of metal materials, and is widely used in the field of metal production and testing.
