Rockwell c44 hardness
WebISO 2039-2 and ASTM D785 define various Rockwell hardness scales for plastics testing. In contrast to ball indention hardness, in which the indention depth is measured under load, with the Rockwell method, the indention depth is measured at a defined preload. There are a variety of indenters available that correspond to the Rockwell scale. WebRockwell hardness of high-speed steel – AISI M2 depends on heat treatment process, but it is approximately 65 HRC.
