Table B is the comparison between HRB, BH, HV and Rm, refer to iron-foundry.com. Table A - HRC to HB, HV, RmTensile strength from Brinell hardness can be roughly estimated by multiplying 3.45 and Brinell hardness is calculated using Tensile Strength = (3.45/9.8067)*Brinell Hardness.To calculate Tensile strength from Brinell hardness, you need Brinell Hardness (HB).With our tool, you need to enter the respective value for Brinell Hardness and hit the calculate button.A Rockwell hardness tester is designed to test the hardness of materials using the differential depth method. A typical Rockwell hardness testing machine consists of a load application feature, an indenter, a test anvil and a .A convenient conversion fact is that of Brinell hardness to ultimate tensile strength. For quenched and tempered steel, the tensile strength (psi) is about 500 times the Brinell hardness number (provided the strength is not over 200,000 psi).

Rockwell Hardness Test. Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load).
The ultimate tensile strength and 0.2% yield strength of this steel correlated well with hot microhardness data at test temperatures up to 400°C using Cahoon's expressions sigmauts = (H/2.9)(n/0. . Performing hardness testing can take many forms, depending on the protocols followed. There are many hardness scales and one of the most common is the Rockwell scale. To convert Rockwell Hardness to Tensile Strength, use a polynomial equation developed by modeling the tested materials.
