high ruptured capacity
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).
The hardness of 4140 plate typically ranges from 28 to 32 HRC (Rockwell C scale) when heat treated to achieve desired mechanical properties.
EN 18 material has a hardness range of approximately 58-64 HRC (Rockwell Hardness). This makes it a relatively hard material suitable for applications requiring good wear resistance and strength.
The unit of hardness is typically expressed in terms of Rockwell (HRC), Vickers (HV), or Brinell (HB) scale depending on the specific test method used. Hardness is a measure of a material's resistance to deformation or indentation.

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.
