The ASTM E140-2005 standard provides metal hardness conversion tables that cover the conversion relationships between Brinell hardness, Vickers hardness, Rockwell hardness, surface hardness, Knoop hardness, and Shore hardness. The standard applies to non-austenitic steels in different states, including carbon steel, alloy steel, and tool steel, as well as nickel and high-nickel alloys, cartridge case brass, austenitic stainless steel, and other materials. These conversion tables make it easy to switch between different hardness standards to suit different industrial applications and testing needs.
