How hard is 60 HRC?
60-62 HRC: Knives of this hardness remain sharp for a long time, but they are at risk of becoming brittle and the knives are often difficult to sharpen. These disadvantages are quite easy to suppress with modern steel types, but the quality depends on the quality of the whole production process.
Which is harder HRB or HRC?
The Rockwell C scale is usually abbreviated HRC (Hardness Rockwell C), while the Rockwell B scale is abbreviated HRB (Hardness Rockwell B). The higher the number, the harder the material, but only relative to other numbers within a given scale. Rockwell B is better for softer steel or relatively hard aluminum.
