Rockwell c37 hardness comparison to grade 8

WebThe Shore hardness scale is an internationally accepted standard that quantifies the hardness of a material. It offers a comprehensive snapshot that makes it one of the most valuable plastics and rubber hardness scales available. The scale operates within a numeric range of 00 to 100, with 00 being the softest material and 100 being the hardest. Web23 Mar 2024 · A Rockwell hardness tester measures the depth of penetration that occurs in the metal when a load is applied. For hard materials like steel, a diamond penetration tool is used. For softer materials, small balls (1⁄16-inch or 1⁄8-inch in diameter) are used and the Rockwell hardness tester measures the depth.
