The simplest response is that Rockwell hardness describes a metal object’s resistance to penetration and permanent deformation by another material, such as a knife blade. It is a system of non-destructive metallurgical testing that assesses the true hardness and strength of steel, such as that used in the manufacture of knives. Engineers employ a common procedure called Rockwell testing to precisely express the hardness of metals.

The Rockwell hardness scale is used by all companies that produce steel products in America. No matter if the product is a ball bearing or a knife blade, the RC scale is the industry standard. Two experts in the field recommend Rockwell testing and how to carry them out.

The apparatus used to measure Rockwell hardness is relatively simple. It entails a mechanical process in which the depth of the indentation is measured as an indenting tool is pressed against the metal subject surface at various rates. The pressure application is precisely controlled by testing professionals based on the type of metal they are working with.
