Table A is the comparison between Rockwell C Hardness, Brinell Hardness, Vickers Hardness and tensile strength (Rm). Table B is the comparison between HRB, BH, HV and Rm, refer to iron-foundry.com. Table A - HRC to HB, HV, Rm Hardness Converter. Given here is an online steel hardness conversion calculator which helps you to calculate the hardness steel of Rockwell HRC, Rockwell HRB and Vickers HV scales. There are a large number of hardness testing methods available (e.g. Vickers, Brinell, Rockwell, Meyer and Leeb).
1) Standard Hardness Conversion for metals acc. ASTM E 140 - 97, September 1999, Conversion for Non-Austenitic Steels, Table 1. The accuracy of the conversion depends on the accuracy of the provided data and the resulting curve-fits.
Hardness conversion table - Tensile strength, Vickers, Brinell och Rockwell (According to DIN 50150) The information below is for guidance only and should not be seen as fixed reference values. Some conditions, especially the incidence of cold work, can change the relationship between the tensile strength and hardness profoundly. AT0012 0311 Hardness Testing Copper Alloy Products
Steel hardness conversion table containing conversion factors for Rockwell, Vickers & Brinell. As a guide we show the theoretical conversion comparison of tonnes tensile in Newtons/mm² and MPa to steel hardness. N/mm² / MPa. Brinell HB. Tons per sq in. Vickers. Rockwell C. Rockwell B.
tensile and hardness test data are both listed, tensile data is precedent and hardness data is reference. Hardness scale conversions are frequently done for convenience, but scale conversions in material properties certifications are not permitted by ASTM.
