EBOOK: BUEHLER HARDNESS CONVERSION CHARTS: HRB, HRC, HBW, HBS ...

Introduction

The requirement to convert from one hardness test scale to another is quite common and as such is covered by various International Standards (ASTM E140, ISO 18265).These standards point out that, due to the differences in the various types of hardness test methods, it is not possible to show a constant conversion relationship across all materials. As such, the standards provide approximate conversions only with defined hardness ranges and test loads for specific materials.Thus there are a number of conversion tables according to material type and it is essential to use the correct one.The following conversion charts have been constructed according to the hardness test scale conversion algorithms provided within ASTM E140. Please treat all converted values as approximations only.
