Rockwell hardness scale is a type of scale that indicates the hardness of a material measured using the Rockwell hardness test. It is a unitless number. The Rockwell hardness scale is symbolized by HR followed by a letter indicating any of the possible scales. For example, "HRC 96" for a metal means the hardness of that metal is 96 when

The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, or the softest material that can scratch the given material. For example, if some material is scratched by topaz but not by quartz, its hardness on the Mohs scale would fall between 7 and 8. Indentation hardness.
