Hardness is one of the key properties of high chrome grinding balls. Due to the high hardness of high chromium alloys, high chromium grinding balls usually have a higher hardness value, which can be expressed by Rockwell hardness (HRC) or Brinell hardness (HB). Common hardness ranges are 58 to 66 HRC or 600 to 800 HB.

Hardness. Hardness can be defined as the resistance of a material to an applied pressure or force. Brinell hardness. The Brinell hardness number is a number proportional to the load or test force of a hard steel ball to the calculated curved area of the indentation formed. The ball diameter is 1, 2.5, 5, or 10 mm.

Solution: BHN = 2P / [ πD (D - √ (D 2 -d 2 )) ] = 2 x 20 / [ π 50 ( 50 - √ ( 50 2 - 15 2 )) ] = 0.11062642329324533. BHN or Brinell Number is the numerical value assigned to the hardness of metals and alloys. The test is to determine the hardness of a metal by pressing a steel ball of a standard size into the metal using a standard force.

The typical brinell hardness test uses a 10 millimeters (0.39 in) diameter steel ball as an indenter with a 3,000 kgf (29 kN; 6,600 lbf) force. For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball. The indentation is measured and hardness calculated as:
