Testing the Hardness of Carbide Spherical Button

The PHR series of portable Rockwell hardness testers are ideally suited for testing the hardness of carbide spherical button, which are mainly tested using Rockwell hardness testers for HRA hardness values. The instrument has the same weight and accuracy as a benchtop Rockwell hardness tester and is very easy to use and carry.

Cemented carbide is a metal, the hardness test can reflect the difference in mechanical properties of cemented carbide materials under different chemical composition, organisation and heat treatment process conditions, therefore the hardness test of cemented carbide is widely used in the inspection of cemented carbide properties, supervision of the correctness of heat treatment process and research of new materials.

Features: It is a non-destructive test and the test method is relatively simple. The hardness test of carbide button is highly adaptable to the shape and size of its test pieces and the test is highly efficient. In addition, there is a certain correspondence between the hardness of the carbide material and other physical properties. For example, the carbide ball tooth hardness test and the tensile test are basically tests of the metal's ability to resist plastic deformation, and both tests are to some extent tests of similar properties of the metal. Therefore, their test results are fully comparable with each other. Cemented carbide tensile testing equipment is large, complex to operate, to prepare specimens, test efficiency is low, for many metal materials, there is a hardness test and tensile test conversion table can be found. Therefore, when testing the mechanical properties of cemented carbide materials, people are increasingly using the hardness test and less often the tensile test.
