This window displays comparative values for the Rockwell "C" and Brinell scales, which are probably the two most-common material hardness designations found on manufacturing blueprints.
Also included is the approximate tensile strength value for steel of a specific hardness, expressed as PSI (pounds per square inch) and MPa (megapascals).
