Understanding Steel: The Rockwell Hardness Scale
The Rockwell Scale is used to determine the hardness of a material, and part C specifically refers to steel. The hardness of a steel is determined by the heat treatment of the blade. In simple terms, the higher the number, the harder the steel. However, one steel is not better than another simply because it is harder.

Understanding the Hardness of Metals | Design News
For example, an extremely hard steel might have a hardness of 64 HRC, while a fairly soft steel might have a hardness of 70 HRB. Which scale is best to use? It depends on what you're measuring. The Rockwell C scale is good for measuring hardened steel. Rockwell B is better for softer steel or relatively hard aluminum.
