Rockwell hardness conversion scale
Web12 Oct 2024 · The hardness is inversely proportional to the depth of penetration. There are many Rockwell hardness scales, depending on the type of indenter and load used. For example, the Rockwell C scale uses a cone-shaped, diamond-tipped indenter with a 150-kg load. The Rockwell B scale uses a 1/16-inch diameter ball indenter with a 100-kg load. WebOn the "M" scale, polycarbonate sheet has a Rockwell hardness of approximately 55-63. The various hardness tests and scales cannot be accurately correlated to each other. Therefore, when cross referencing scales, values are not reliable. Each Rockwell scale involves the use of a different diameter indenting device and a different applied weight.
