Mar 26, 2015· 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. Different steels are known to perform best within different Rockwell ranges.
The required hardness can be achieved by varying the tempering temperature within the specified range. Furnace types. Knife steel can be hardened in two different ways, depending on the equipment used: Piece hardening in a small furnace, or on a belt furnace. The hardening procedure, times and temperatures, is the same for both furnace types.
A well-done and consistent heat treat goes a long way towards the performance of a knife. High hardness (60 HRC+) increases the edge retention of the steel at the cost of brittleness. Low hardness increases toughness at the cost of edge strength. The effect of heat treat varies based on the composition of the steel.
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. When a range is listed, it means that whatever …

Most knife manufacturers display the hardness number as “HRC xx,” where “xx” corresponds to the Rockwell hardness number. Very few blades measure over HRC 70, while most functional knives have a rating somewhere between HRC 56 and HRC 63.
The hardness of a knife is very important as far as its performance and durability. For instance, a harder steel with a RC of 58-62 will hold an edge better than a softer steel. However, that same harder steel is less durable and more prone to chipping or even breaking. Some kitchen knives with high hardness …
For best performance, we harden to a standard Rc 58-60. 420HC Steel This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels.
After a hardening process at 1040 °C and annealing at 160 °C the blades achieve an average hardness of 56 HRC. This steel hardness is suitable for practical use and easy resharpening, but less than achieved in stainless steel alloys used for blades optimized for high wear resistance. According to Victorinox the martensitic stainless steel alloy used for the other parts is X39Cr13 (aka DIN 1.4031, …
