The hardness of cemented carbide is generally detected by Rockwell hardness tester HRA scale or Vickers hardness tester,In practice, people mainly use Rockwell hardness tester to test HRA hardness.tungsten carbide hardness can reflect the difference in mechanical properties of cemented carbide materials under different chemical composition, organizational structure and heat treatment process conditions. Therefore, hardness testing is widely used in Inspection of cemented carbide properties, supervision of correctness of heat treatment process and research of new materials.
Cemented carbide hardness monitoring is a non-destructive test, the test has strong adaptability to the shape and size of the test piece, the test efficiency is high, and the test method is relatively simple. In addition, there is a certain correspondence between the hardness of cemented carbide materials and other physical properties.
In practice, it is often necessary to convert the HRC and HRA hardness standard,which is shared as below table.
The portable Rockwell hardness tester is also very suitable for testing the hardness of cemented carbide. This instrument is light in weight and easy to carry. It is simple, fast and non-destructive to test cemented carbide semi-finished products piece-by-piece.For more industry information, welcome to follow Oston Carbide!
