Steel Hardness Conversion Table

97 行  Reference table: Steel Hardness conversion chart. Since the various types of hardness tests do not all measure the same combination of material properties, conversion from one hardness scale to another is only an approximate process. Because of the wide range of variation among different materials, it is not possible to state confidence limits for the errors in using a conversion chart. Tool ...

STANDARDIZATION OF THE LEEB Impact body HARDNESS

Conversion tables for the common hardness scales are given in the ASTM E 140 or DIN 50 150 standard. But it is to consider that those tables are only valid for unalloyed and low-alloyed steel grades, and therefore reflects material group number 1 (see Table 1). If measurements have to be carried out on high-alloy steels or other materials, e.g. nonferrous metals, then the instrument has to be ...
