Hardness Testing of Cemented Carbides

ASTM B294

This test method covers the hardness testing of cemented carbides by use of a Rockwell hardness tester performing tests in the Rockwell HRA scale (regular scale, diamond indenter, 10 kgf [98.07 N] preliminary test force, and 60 kgf [588.4 N] total test force in the range of Rockwell 80 HRA and above). Also covered are the procedures for the testing and selection of diamond indenters, the management and traceability of the four levels of standardized test blocks, and the making and calibration of Primary, Secondary, and Working standardized test blocks. The Rockwell hardness tester is a convenient and reliable means of measuring the hardness of cemented carbides. A hardness value is obtained easily, but it is subject to considerable error unless certain precautions are observed.

WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM B294 for Hardness Testing of Cemented Carbides. Contact us to learn more.
