The hardness of 50-55 HRC (Rockwell C scale) indicates the material's resistance to deformation and wear, commonly used to assess the hardness of steel and other hard materials. A hardness value in this range suggests that the material is quite hard and suitable for applications requiring durability, such as cutting tools and industrial components. This level of hardness typically implies a balance between hardness and toughness, allowing the material to withstand stress without fracturing.
The Mohs hardness of sodium chloride is 2,5.
the mineral that has a hardness of 7 is "Quarts

A steel nail cannot scratch minerals that are harder than itself, which has a Mohs hardness of about 4.5. This means it cannot scratch minerals such as quartz (hardness 7), topaz (hardness 8), corundum (hardness 9), and diamond (hardness 10). These minerals possess greater hardness and will resist scratching by a steel nail.
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.
55-58 HRC (Rockwell Hardness) typically indicates a high level of hardness and wear resistance in metals or materials. It signifies that the material has been heat-treated to achieve this level of hardness, making it suitable for applications requiring durability and strength, such as cutting tools or industrial components.

The full form of HRC is Rockwell Hardness C Scale. It is a measure of the hardness of a material, typically metals, determined by how much force is required to create an indentation on the surface of the material.
It can range from 10 HRc to 50 HRc it's all dependent on how it's heat treated and quenched.
