... with hardness testing, was widely used prior to the adoption of hardenability analysis. As an illustration, Fig. 19 shows discs cut from round bars of AISI 1060 carbon steel ranging in size from a diameter of 20 to 65 mm (¾ to 2½ in.). The two smallest sizes were through hardened, that is, the center region...
