The "10" is the ball diameter in millimeters. The "3000" is the force in kilograms force. The hardness may also be shown as XXX HB YYD 2. The XXX is the force to apply (in kgf) on a material of type YY (5 for aluminum alloys, 10 for copper alloys, 30 for steels). Thus a typical steel hardness could be written: 250 HB 30D 2. It could be a ...
