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
Brinell Hardness Number Definition of Brinell Hardness Definition of Brinell hardness number. :a number eing Brinell hardness and denoting the load applied in testing in kilograms divided by the spherical area of indentation produced in the specimen in square millimeters. called also Brinell number.
Jun 02, 2014 · Brinell Hardness Test Equations, Calculators and Review The Brinell hardness test uses a hardened steel ball indenter that is pushed into the material under a specified force. The diameter of the indentation left in the surface of the material is measured and a Brinell hardness number is calculated from this diameter.
Brinell Hardness Test:Introduction, Procedure, Formula Specifying Brinell Hardness Number While specifying a Brinell hardness number (BHN or HB), the test conditions used to obtain the number must be specified. The standard format for specifying is HBW 10/3000. HBW refers to a tungsten carbide ball used as an indenter, as opposed to HBS, which means a hardened steel ball.

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 Definition of Brinell hardness a measure of the hardness of a material obtained by pressing a hard steel ball into its surface; it is eed as the ratio of the load on the ball in kilograms to the area of the depression made by the ball in square millimetres Word Origin for Brinell hardness number C19:named after Johann A. Brinell (18491925), Swedish engineer
Brinell hardness test measurement BritannicaBrinell hardness is determined by forcing a hardened steel or carbide ball of known diameter under a known load into a surface and measuring the diameter of the indentation with a microscope. The Brinell hardness number is obtained by dividing the load, in kilograms, by
Brinell hardness of cartridge brass UNS C26000 is approximately 100 MPa. Brass is is the generic term for a range of copper-zinc alloys . Brass can be alloyed with zinc in different proportions, which results in a material of varying mechanical, corrosion and thermal properties.
Wheel weights and Brinell Hardness NumbersJan 17, 2013 · I converted SAECO hardness numbers to BHN The air-cooled boolits tested at a SAECO hardness of 6.5 which converts to a BHN of 10 as could be expected of wheel weights I then tested the water-cooled boolits and they showed a SAECO hardness of 10. That converts to a BHN of 22 or equivalent to linotypeBrinell Hardness Number - Brinell Scale nuclear-power.netThe Brinell hardness number (HB) is the load divided by the surface area of the indentation. The diameter of the impression is measured with a microscope with a superimposed scale. The Brinell hardness number is computed from the equation:There are a variety of test methods in common use (e.g. Brinell, Knoop, Vickers and Rockwell).
