Hardness scales and range
(according to relevant standards), in this case table A1 respectively T1, T2 (low alloy steel). Different measuring ranges are valid for other materials. When exceeding the limits the conversion range will be extended. The calculated values are highlighted in red besides the original data in HV.
Note:
Conversions are acc. to latest ASTM E140-12bԐ1 (2013) and EN ISO 18265:2014.
Conversions into tensile strength: 98N (10kgf) test load only.
