The load (usually 50 kgf, but could be 5, 10, 20, 30, or 120 kgf) is applied via the pyramid against the smooth, firmly-supported, flat surface of the test specimen for 30 seconds. Hardness Conversion Calculator, Brinell Vickers Rockwell Knoop Scleroscope, HRB HB HR15T HR30T, Hardness Conversion Calculator for Stainless steel and other metals. The accuracy of the conversion depends on the accuracy of the provided data and the resulting curve-fits, and on the valid ranges spanned by the different hardness tests. Symbol: HV : The Vickers Hardness test can be applied to different materials across a very wide range of hardnesses. The calculator curve-fits multiple hardness data onto a common polynomial basis and then performs an analytic conversion. Values are given to four significant figures (the odd result may show 9's or 0's over running). As a guide we show the theoretical conversion comparison of tonnes tensile in Newtons/mm² and MPa to steel hardness. All results shown will be equivalent values. 10mm Standard Ball, 3000 Kgf (HBS): Vicker's Hardness Number (HV): Rockwell Hardness Number B Scale, 100 Kgf (HRB): Rockwell Hardness Number E Scale, 100 Kgf (HRE): Rockwell Hardness Number H Scale, 60 Kgf (HRH): Rockwell Superficial Hardness No. Approximate Hardness Conversion Numbers for Wrought Aluminum Products: Brinell Hardness No. Steel Hardness Converter Steel hardness conversion table containing conversion factors for Rockwell, Vickers & Brinell. Estimated Hardness Equivalents between Vickers and Rockwell C Please note the chart above is only intended to give a rough idea of the relationship between Vickers and Rockwell C hardness scales. Steel Hardness conversion calculator: Brinell Hardness HB: Rockwell C - HRC: Rockwell B - HRB: Vickers - HV : Enter a figure into any of the fields and click calculate, the nearest values in each scale is shown, or zero if out of range. It should not be used or relied upon to give accurate conversion. HV = Vickers hardness To convert HV to MPa multiply by 9.807 To convert HV to GPa multiply by 0.009807 To use the conversion calculator simply enter a number value into the desired field and click calculate. The Vickers test uses a square-based diamond pyramid with a 136º point angle. Enter a from value, select the from units, enter the “to” units, and G-Wizard will give you a value (if there is one) in the new hardness units. Hardness conversion calculator for Rockwell, Brinell, Vickers, Shore Scleroscope, and Tensile Strength… The Hardness Conversion Calculator is particularly handy.
