jan 30 2015· yes rockwell hardness is determined by an alternative method to brinell hardness but relates in a direct linear way to compressive and yield strength a non-destructive means of testing by indenting (compressing) the piece over a small area. typical knife-blades are hardened to >55rc to resist deformation of the thin cutting edge.
since brinell hardness is a mechanical property it also relates to the material's resistance to wear as well as plastic or permanent deformation and the material's ability to indent or abrade another material. brinell hardness is named after johan a. brinell a swedish engineer.
