Brinell Hardness

แปลว่า(english) The hardness of a metal or part, as represented by the number obtained from the ratio between the load applied on the spherical area of the impression made by a steel ball forced into the surface of the material tested.

Brinell Hardness Number

แปลว่า(english) The value of hardness of a metal on an arbitrary scale representing kg/mm2, determined by measuring the diameter of the impression made by a ball of given diameter applied under a known load. Values are expressed in Brinell Hardness Numbers, BHN

Brinell Hardness Testing

แปลว่า(english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function.
