Hardness comparison table. Brinell HB (10 mm Ball, 3000 kg load) Vickers HV (5 kg) Rockwell C HRC (120 degree cone 150 kg) Rockwell B HRB (1/16" ball 100 kg)
These prices are more an indication than an actual exchange price. Unlike the prices on an exchange, pricing providers tend to give a weekly or bi-weekly price. For each commodity they quote a range (low and high price) which reflect the buying and selling about 9-fold due to China's transition from light to heavy industry and its focus on ...
Steel classification according to EN 10027-2.Free searchable database "European steel and alloy grades" Comparison of various steel standards Archived 2019-04-27 at the Wayback Machine; Comparison of various tool steel standards; General guide to the EN 10027 steel name and numbering systems.
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
SVCM steel is a kind of shock-resisting steel. [5] SVCM steel is an alloy of carbon, silicon, chromium, magnesium, nickel, molybdenum and lead. [6] SVCM+ in addition is quenched and tempered achieving a high hardness (HRC 59). [6] SCVM+ has better torsional properties than chromium-vanadium steel (Cr-V). [7]
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.

The typical test uses a 10 mm (0.39 in) diameter steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force. For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball. The indentation is measured and hardness calculated as:
