Standard Test Method for Hardness Testing of Cemented Carbides

Importancia y uso:

3.1 Rockwell hardness testing is one of the more important methods used to evaluate cemented carbides. For compositional groups of cemented carbides, hardness is an indication of wear resistance and toughness. Lower hardness grades usually indicate less wear resistance but greater toughness. For a specific grade of cemented carbide, hardness is an indication of the metallurgical quality of the material. In no case is Rockwell hardness testing the only test method to be considered in evaluating cemented carbides.
