Hardness Conversion Chart: Brinell (BHN) to Rockwell B and C
Different testing scales are used to measure the hardness of various materials. In mechanical engineering and manufacturing, Brinell (BHN), Rockwell B (HRB), and Rockwell C (HRC) are commonly used hardness scales. Sometimes, a material’s hardness is tested on one scale, while the drawing, material specification, or engineering requirement specifies the hardness on a different scale. … Read more
