What is the Rockwell hardness test?
Measure the depth of the indenter under any test conditions! A testing method with a small indentation.
The "Rockwell hardness test" is a hardness measurement based on the increase in depth of the indentation when a load is applied. It is generally given on the B, C, R, L, M, E, and K scales, with higher values on each scale indicating harder materials. In the Rockwell hardness testing method, the depth of the indenter is measured under any testing conditions. 【Scales and Hardness Values】 ■ Examples of Hardness Standards Very hard steel: HRC55・HRC2 Shafts, chisels, etc.: HRC40・45 ■ ASTM Standards E18 Rockwell hardness and Rockwell surface hardness ■ EN-ISO Standards 6508 Rockwell hardness and Rockwell surface hardness of metallic materials *For more details, please refer to the PDF document or feel free to contact us.
