Descriptions
Hardness is an important indicator of a material’s mechanical properties. It refers to the ability of a material to resist indentation by another object without undergoing residual deformation. Among mechanical property tests, the Rockwell hardness test is one of the simplest, fastest, and most economical methods. Because it can directly indicate hardness values, it offers the highest testing efficiency. In many cases, it can perform tasks that other mechanical property tests cannot. With the rapid development of research and industry in our country, the Rockwell hardness testing method has been widely used in national defense, scientific research, laboratories, and factory workshops.
