WebWhen a steel ball is used, the result is written as BHN or HBN, example 285 HBN. When a tungsten ball is used, the result is written as HBW, W is the chemical symbol for tungsten (wolfram). Brinell testing is generally considered to be more accurate because the larger ball size makes deeper and wider indentations, thereby averaging the test out over a wider … WebHardness conversion. Conversion of hardness-to-hardness or hardness-to-tensile-strength values for unalloyed and low-alloy steels and cast iron. Metallic materials, conversion of hardness values.
