The Brinell Hardness of High Carbon Steel constant displays the value of the Brinell hardness for high carbon steel AISI 1095 (200 BHN).
Brinell hardness test determines the ability of a metal to resist permanent indentation deformation through the scale of penetration of an indenter that is loaded onto a material sample. Brinell hardness is one of several definitions of hardness for materials science.
The Brinell hardness of high carbon steel is 200 Brinell hardness numbers (BHN).
