Web26 mrt. 2015 · A lower Rockwell number means that the steel is softer, relatively speaking, while a higher number indicates a harder steel. Sometimes you'll see Rockwell hardness expressed as a single value, like "59 RC," and other times as a range, like "58-60 HRC." A steel's final hardness is established by the knifemaker during the heat-treating process. insulated conservatory roof replacement
