in some similar characteristics detection of metal

It belongs to the non-destructive testing, test method is relatively simple. W. Carbide hardness test specimen of its shape and size adaptability, test efficiency. . In addition, carbide hardness and other physical properties of materials, there is a certain relationship between the. For example, the carbide hardness test and tensile test are basically detect metal plastic deformation resistance capacity, which both tests are, in some similar characteristics detection of metal. . Therefore, the test results are compared with each other completely. Carbide tensile test equipment is huge, complex operation, to sample preparation, tungsten carbide inserts efficiency is low, for many metals, has a hardness test and tensile test conversion tables to be investigated. Therefore, the mechanical properties of carbide materials testing, people increasingly using hardness test, and less by tensile tests.
Tool
Carbide hardness is generally used scale Rockwell hardness HRA or Vickers hardness tester to detect, practical people mainly used in Rockwell hardness test Hardness HRA. PHR Series Portable Rockwell hardness tester is suitable for testing the hardness of cemented carbide. . This instrument weighs only 0.7kg, the accuracy and the same desktop Rockwell hardness. . Carbide measuring hardness, Star company's PHR Series Portable Rockwell Hardness Tester can test the thickness or diameter of less than 50mm carbide workpiece, you can test a small diameter to 2.0mm carbide workpiece diameter smaller than can be tested 30mm tubular carbide workpieces. You can also at the production site and sales site or materials warehouses.. The instrument used to test the carbide workpiece is simple, fast, non-destructive, can be finished or semi-finished products for the bulk of the work done by piece carbide hardness testing
