The hardness level of steel is determined using a universal scale called the “rockwell c test”, commonly called the rockwell hardness scale (hrc). Brinell hardness of mild steel is approximately 120 mpa. The ability of steel to retain its original shape is measured on the rockwell c scale, also known as hardness rockwell c (hrc).
