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

What is Hardness?

Hardness is a mechanical property that describes how much a material resists deformation, compression, scratching, or wear against an external force. Hardness is considered a basic and important property in engineering and materials science, because it directly indicates how durable and reliable a material is. The industrial use of a material is determined by its … Read more
