< ( ' ' SongTi/> ( ' ' SongTi Carbide Hardness Testing Mainly Uses Rockwell Hardness Tester to Test Hardness value. The series of portable Rockwell hardness testers are very suitable for testing the hardness of cemented carbide. The weight accuracy of the instrument is the same as that of the desktop Rockwell hardness tester, and it is very convenient to use and carry.
< ( ' ' 宋体/> ( ' ' 宋体/> Alloy is a kind of metal. The hardness test can reflect the differences in mechanical properties of cemented carbide materials under different chemical compositions, organizational structures and heat treatment process conditions. Therefore, hardness tests are widely used to inspect the performance of cemented carbide and supervise the correctness of the heat treatment process. and research on new materials.

< ( ' ' 宋体/> ( ' ' 宋体 It is a non-destructive test and the test method is relatively simple. Hard The hardness testing of alloys has strong adaptability to the shape and size of the test piece and high testing efficiency. In addition, there is a certain correspondence between the hardness of cemented carbide materials and other physical properties. For example, cemented carbide hardness testing and tensile testing are basically Both tests detect the ability of metals to resist plastic deformation. To some extent, both tests test similar properties of metals. Therefore, their test results are completely comparable to each other. The cemented carbide tensile testing equipment is large, complex to operate, and requires Sample preparation and test efficiency are low. For many metal materials, there is a conversion table for hardness test and tensile test. Therefore, when testing the mechanical properties of cemented carbide materials, people increasingly use hardness tests and rarely use tensile tests. .
