HRC stands for Hardness Rockwell C scale. There are different scales; C is probably the most common for hardened materials. See the related link for more information.

Bennox is a type of stainless steel known for its high hardness and corrosion resistance, typically used in cutlery and industrial applications. The Rockwell hardness of Bennox can vary depending on the specific alloy and heat treatment, but it generally falls within the range of 56 to 60 HRC. This hardness level contributes to its durability and edge retention in cutting tools.
The Rockwell scale measures the hardness of materials, particularly metals, using a standardized method that involves applying a specific load to an indenter and measuring the depth of penetration. Different Rockwell scales (e.g., A, B, C) are used for various materials, with the C scale commonly applied to harder materials like steel. The scale provides a straightforward numerical value that indicates hardness, where higher numbers correspond to harder materials. Thus, the hardness of a file, which is typically made from high-carbon steel, would be relatively high on the Rockwell scale, often around 60 HRC or more.

It can range from 10 HRc to 50 HRc it's all dependent on how it's heat treated and quenched.
The Rockwell C Hardness system uses "HRC" as a measure of hardness for various materials. A hardness of 68 HRC is extremely high and will most likely be harder than simple steel.

In rockwell, it should be between 23-32 HRC
If 35 HRC is high on the Rockwell scale or not is quite relative to what you would define as high. A typical axe would rate at around 45-55 HRC, while high quality steel knives would rate at about 55-66 HRC.

In depends on the hardfacing technique and the final Fe dilution. Typical values range 42-45 HRC.
Sterling silver typically has a hardness of around 40 to 45 HRC on the Rockwell scale.
