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.
Before heat treatment, D2 tool steel typically has a Rockwell hardness in the range of 20 to 30 HRC (Rockwell C scale). The hardness can vary depending on the specific processing and manufacturing methods used. After heat treatment, the hardness can significantly increase, often reaching 55 to 62 HRC.

The Rockwell hardness of S7 steel typically ranges from 50 to 55 HRC (Rockwell C scale) after proper heat treatment. This high hardness level makes S7 steel suitable for applications requiring toughness and wear resistance, such as tooling and dies. Its specific hardness can vary based on the heat treatment process applied.
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 hardness of FXT2 steel typically ranges around 60 HRC (Rockwell C scale), depending on the specific heat treatment and processing it has undergone. This high hardness makes FXT2 steel suitable for applications requiring superior wear resistance. However, exact values may vary based on the manufacturer's specifications and the final treatment of the steel. Always refer to technical datasheets for precise hardness values.
28 - 32 hrc
42 to 45 HRC
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.
HRC 23-34 According to ASTM F568M (1996)
Before heat treatment, D2 tool steel typically has a Rockwell hardness in the range of 20 to 30 HRC (Rockwell C scale). The hardness can vary depending on the specific processing and manufacturing methods used. After heat treatment, the hardness can significantly increase, often reaching 55 to 62 HRC.
hardness as it is measured on a rockwell or brinell testing instrument
ANSWER: Rockwell (HRC) 50.Grade 420 stainless steel (Fe,
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.
