Minimum hardness is about 50 HRC, but, though the alloy is specific, there are a variet of heat treatments that can push this figure around quite a bit. A link is provided to the site of a supplier, and some good data on H13 steel can be reviewed there.

if its standard wrought carbon steel, the psi should be just about in the 100,000psi range. The last two digits of the designation, 75, are the carbon content. 0.75%. the higher the carbon content, the higher the tensile strength. The ultimate tensile strength of a steel such as AISI 1075 varies depending upon the heat treated condition and hardness. The tensile strength of a steel can be approximated from the hardness using hardness conversion tables found elsewhere on the web.
Hitachi Blue Steel, also known as Aogami, is a high-quality tool steel produced by Hitachi Metals. It is renowned for its exceptional hardness, edge retention, and ease of sharpening, making it a preferred choice for high-performance kitchen knives and other cutting tools. The steel is typically alloyed with high carbon content and small amounts of chromium and tungsten, which enhance its durability and resistance to wear. Two primary variants, Aogami #1 and Aogami #2, offer different balances of hardness and toughness for various applications.
Welding EN42 steel, a high-carbon steel known for its hardness and strength, requires specific techniques to ensure a strong joint. Preheating the steel to around 200-300°C (392-572°F) helps reduce the risk of cracking. Using suitable filler materials, such as low-alloy steel electrodes, and post-weld heat treatment can improve ductility and relieve residual stresses. Proper shielding gas and welding methods, like TIG or MIG, are also essential for achieving a quality weld.

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.
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.
