Brinell hardness number

n. Abbr. Bhn or HB The numerical value assigned to the Brinell hardness of metals and alloys. Also called Brinell number.

Brinell hardness number

(brɪˈnɛl) n (General Engineering) a measure of the hardness of a material obtained by pressing a hard steel ball into its surface; it is expressed as the ratio of the load on the ball in kilograms to the area of the depression made by the ball in square millimetres[C19: named after Johann A. Brinell (1849–1925), Swedish engineer]

Bri•nell′ hard′ness num`ber

(brɪˈnɛl)
n. a rating obtained from a test (Brinell′ test`) to determine the hardness of a metal by pressing a steel ball of a standard size into the metal using a standard force. Abbr.: Bhn [after J.A. Brinell (1849–1925), Swedish engineer]

Brinell hardness number

Bri·nell hard·ness num·ber (BHN),

(bri-nel'), a number related to the size of the permanent impression made by a ball indenter of specified size (usually 10 mm in diameter) pressed into the surface of the material under a specified load:

where P = applied load in kg, D = diameter of the ball in mm, and d = diameter of the impression in mm.
