Vickers hardness of Co-Cr-Mo alloys were investigated as a function of Cr and N contents for dental applications. The hardness of 33Cr was highest in the N-free alloys because of the existence of the inclusion. In the N-contained alloy, the increase of the hardness was confirmed at 29Cr and 33Cr. Solid solution hardening may occur because the inclusion in 29Cr was not observed. Although the hardness of N-contained 33Cr was as high as that of N-free 33Cr, the yield strength of N-contained 33Cr was twice higher than that of N-free 33Cr.
