Lee hardness chart
NettetThis article details the Brinell to Rockwell hardness conversion chart, which explains how the test results of one scale can be translated into another. The Brinell and Rockwell scales use varying levels of force to determine an object’s hardness. However, these two systems use different formulas to calculate this value. NettetThe LEE Reloading Manual, and the chart included, explain how to express Brinell hardness as Yield Strength. LEE claims that the best accuracy is obtained when …
