WebThe Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters. WebRockwell hardness: 85 HRB. Hardening Heating to austenitizing temperature 925-1010 °C (1700-1850 °F), the usual time at the temperature range is 30-90 minutes, the quenching agent is air or oil (for parts thicker than 6.4 … hot tubs and babies
