22HRC applies for some carbon and low alloy steels, but 22HRC is not the hardness limit for all materials. The conversion of hardness readings to and from other scales is material dependent; there are hardness conversion tables such as ASTM E140, ISO 18265 . As per NACE MR0175, the user may establish the required conversion tables.
Carbon and Alloy Steel Chemical Composition Specification 1045 Medium carbon steel. often used for bolts, studs and shaft parts. High strength and hardness. Hot Rolled Carbon Steel. 1018, 1020 (HR,CF) - Low carbon steel. Has good hardening properties, fair machinability. Readily brazed and welded. 1117 (HR,CF) - Low carbon, high manganese steel. Good machinability, case hardening is deep and uniform.
HBS indicates that the indenter is a hardened steel ball, which is used to determine materials with a Brinell hardness value below 450, such as mild steel, gray cast iron and non-ferrous metals. HBW indicates that the indenter is a hard alloy, which is used to measure materials with a Brinell hardness value below 650.

Standard Hardness Conversion Tables for Metals austenitic steels including carbon, alloy, and tool steels in the as-forged, annealed, normalized, and quenched and tempered conditions provided that they are homogeneous. 1.3 Conversion Table 3 presents data on the relationship among Brinell hardness, Vickers hardness, Rockwell hardness, Rockwell superÞcial hardness, and Knoop hardness of nickel
Steel Hardness Converter Steel hardness conversion table containing conversion factors for Rockwell, Vickers & Brinell. As a guide we show the theoretical conversion comparison of tonnes tensile in Newtons/mm² and MPa to steel hardness.
Steel hardness test methods and hardness conversion - The hardness of steel is important to many processes. Steel hardness describes the
carbon steel hardness chartHardness Conversion Table for Carbon and Alloy Steels. Brinell Testing is a fairly simple test but the most destructive type. It requires more sample preparation and can at times require destruction of a finished part. A defined load of 500-kg to 3000-kg is applied through a 10 mm hardened steel .
