Which hardness test method is suitable for cemented carbide Inserts

Hard alloy hardness testing mainly adopts Rockwell hardness and HRA hardness value. The PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide. The weight accuracy of the instrument is the same as that of the desktop TCMT Insert Rockwell hardness tester, and it is very convenient to use and carry.

In the Rockwell hardness test, using different indenters and different test forces will produce different combinations, corresponding to different scales of Rockwell hardness. There are 3 rulers commonly used, and their applications cover almost all commonly used metal materials.

Rockwell hardness (HR) test, when the tested sample is too small or the Brinell hardness (HB) is greater than 450, the Rockwell hardness measurement is used instead. The test method is to use a diamond cone with an apex angle of 120 degrees or a steel ball with a diameter of 1.5875mm/3.175mm/ 6.35mm/12.7mm, which is pressed into the surface of the tested material under a certain load, and the material is obtained from the indentation depth The Carbide Turning Inserts hardness.

Hard alloy hardness is generally tested with Rockwell hardness tester HRA scale or Vickers hardness tester. In practice, people mainly use Rockwell hardness tester to test HRA hardness. The PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide. This instrument weighs only 0.7kg and has the same accuracy as the desktop Rockwell hardness tester.

When measuring the hardness of cemented carbide, the PHR series portable Rockwell hardness tester produced by Tianxing Company can test cemented carbide workpieces with a thickness or diameter of less than 50mm, and can test cemented carbide workpieces with a diameter as small as 2.0mm. 30mm tubular carbide workpiece. It can also be used at the production site, sales site or material warehouse.

This instrument is used to test cemented carbide workpieces easily, quickly, and without damage, and can perform piece-by-piece hardness testing on batches of finished or semi-finished cemented carbide workpieces.
