• Usually steel balls are used in Brinell hardness test and also in Rockwell hardness test. In Japan, tungsten carbide balls have been recently made in such sizes that we could use them as indenters in ordinary tests. In this research, these balls were used to measure the hardness of hard metals and their permanent deformation was observed to determine the maximum hardness values which we could measure with such balls without their permanent set, and also the difference between hardness values of the same metals was measured with balls of different materials to prepare the new conversion table of hardness. This tabls was compared with the already issued one such as ASTM table. and then disagreement between them was discussed.
