Understanding Rockwell | AGRussell high hardness hrc 58

When looking at knives you will often see a number in the specs with RC after it. This number 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.Understanding Rockwell Hardness in Knives at KnifeArt high hardness hrc 58For instance, a harder steel with a RC of 58-62 will hold an edge better than a softer steel.

FAQ: What Does 'RC' Or 'HRC' Mean In A Knife's high hardness hrc 58

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.Crucible Tool Steel and Specialty Alloy General InformationTo retain maximum hardness (over about 58 HRC), A2 and D2 are usually tempered around 400/500°F. Higher exposures result in lower hardness. A side benefit of high alloy content, typical of high speed steels, and most of the high wear resistance CPM steels, is that the tempering characteristics are changed because of the alloy content.A high hardness, corrosion and fatigue resistance high hardness hrc 58required hardness often exceeds 55 or even 58 HRC. The choice of stainless grades then becomes quite limited. Starting from the high alloyed martensitic steels down to precipitation hardening stainless steels, hardness and abrasion resistance decrease while corrosion resistance increases.
