WebConverting hardness Rockwell B (HRB) to hardness Rockwell C (HRC) is a usual practice for many designers when specifying the hardness value of a material. This conversion is possible using charts and tables calculated using formulas to get approximate but acceptable values that can be interchanged for the different Rockwell hardness testing … WebBHN = F ÷ A where A is the surface area of the indentation: A = ½.π.D x ( D - √ [D²-d²] ) A certain amount of intelligence is required to use this method accurately in that insufficient and/or excessive depth of impression will result in misleading or inaccurate results. The optimum depth will be between 2.5 and 4.75mm for a standard 10mm ball.

WebOct 12, 2024 · In the Rockwell test, an indenter is pushed into a metallic surface with a given force. The hardness is inversely proportional to the depth of penetration. There are many Rockwell hardness scales, depending on the type of indenter and load used. For example, the Rockwell C scale uses a cone-shaped, diamond-tipped indenter with a 150 … defining int array in java
