Understanding Steel: The Rockwell Hardness …
14.10.2016· Steel with a high nuer on the Rockwell scale will have higher edge retention but lower toughness. Likewise, steel with a lower Rockwell Hardness rating will not hold its edge for as long, but will be tougher. Axes and survival blades may tend to have low HRC ratings, making them tough enough to function well under frequent abuse and hard work.

Hardness - Wikipedia
Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion.Some materials (e.g. metals) are harder than others (e.g. plastics, wood).Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness
Understanding Rockwell | AGRussell
When looking at knives you will often see a nuer in the specs with “RC” after it. This nuer represents the Rockwell Rating. The Rockwell rating is a scale that is used to measure the hardness of a material. An example is stainless steel AUS-8, which usually 57-59 Rc. The Rockwell hardness test is the industry standard for knives.
Non-oxide Ceramics – Silicon Carbide (SiSiC/SSiC)
The non-oxide ceramic silicon carbide (SiSiC or SSiC) is a ceramic material that is as hard as diamond and features many other important characteristics. The lightest and hardest ceramic material CeramTec offers is available as SSiC (sintered silicon carbide) and SiSiC (silicon infiltrated silicon carbide).
Hardness - Hard Materials
Brinell Hardness Test. Brinell hardness test is one of indentation hardness tests, that has been developed for hardness testing. In Brinell tests, a hard, spherical indenter is forced under a specific load into the surface of the metal to be tested. The typical test uses a 10 mm (0.39 in) diameter hardened steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force.
