Rockwell hardness
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.
chrome vanadium steel is designated C41-55.
63-65
According to the ASME, SAE1010 {ASTM A179, ASME SA179} cold rolled steel (cold drawn) should have a Rockwell hardness of 60 RB. Hot rolled it is reduced to 55 RB. *(Brinell hardness, 105; Knoop hardness, 123; or Vickers hardness, 108)

The hardness of UST-36 steel is usually around 197-235 HB (Brinell hardness) or 20-23 HRC (Rockwell hardness).
The hardness of 1730 steel can vary depending on the heat treatment process it has undergone. However, it typically has a hardness in the range of 58-63 HRC (Rockwell Hardness).
chrome vanadium steel is designated C41-55.
Molybdenum steel typically has a Rockwell hardness of around 60-63 HRC, indicating that it is a very hard material suitable for applications requiring high wear resistance.
