Hardness Conversion Standard Reference & Integrity Guardrail

Mat Grades strictly enforces metallurgical integrity by preventing mathematical or linear conversions between incompatible hardness scales (e.g. Rockwell B vs Rockwell C vs Brinell). Indentation hardness reflects elastic recovery, indenter geometry, and strain hardening.

Test Value:

From Hardness Scale:

To Hardness Scale:

Metallurgical Governance Rule:

Arbitrary linear hardness conversion is prohibited by engineering data governance. Hardness conversions require empirical material-specific correlation tables (ASTM E140 / ISO 18265).

For safe conversions across scales, refer directly to ASTM E140 (Standard Hardness Conversion Tables for Metals) and ISO 18265 empirical tables specific to the alloy family and heat treatment.
