Notes:

  1. Volume hardness of balls HRCo is determined by the formula:
    OH = 0.289 Tsurf + 0.436 T0.25R + 0.203 T0.5R + 0.063 T0.75R + 0.009 Tц, where Tsurf; T0.25R; T0.5R; T0.75R - hardness value HRC on the surface, at a distance from the surface of the ball
  2. Impact energy is determined by the formula E = m x g x h (J), where h - height of the drop (m), m - mass (kg); g - 9.8 m/s².
