Brinell Hardness Number - BHN - Engineering ToolBox
WebFor plain carbon steels, the approximate relationship between the hardness and tensile strength is: Tensile strength = Bhn × 515 (for Brinell numbers up to 175) Tensile strength = Bhn × 490 (for Brinell numbers larger than 175) The above formulas give the tensile strength in pounds per square inch for steels. WebBHN = Brinell Hardness Number P = load on the indenting tool (kg) D = diameter of steel ball (mm) d = measure diameter at the rim of the impression (mm) It is desirable that the test load are limited to a impression diameter in the range of 2.5 to 4.75 mm.
