Description
A numerical measurement of the hardness of a material. The Rockwell hardness is determined by dropping a steel ball or diamond-tip cone of given diameter from a set distance on the test piece then measuring the size of the indentation. The resulting number is specified with a prefix that gives the load and type of indentor, i.e., HRC 30.
