Hardness and Tensile Strength of Steels: Brinell and Rockwell Scales Following is an estimate of the relationship between various hardness scales and the tensile strength of standard steels. It should be considered as a general comparison not applicable to all materials:Rockwell Hardness Test and the Effect of Treatment on SteelIn Rockwell-type testing, loaded indenters of various sizes and shapes measure hardness. For this experiment, we will measure and compare the hardness of untreated and heat-treated steel using the Rockwell hardness test. Several common methods to measure the hardness of metals include Brinell, Vickers, Knoop, and Rockwell hardness BNC.AISI 4140 Alloy Steel (UNS G41400) - AZoM rockwell b hardness 4140 steelAISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).
