The SAE J 417-1983 standard provides a guide to metal hardness testing and hardness value conversion, including test methods and conversion values for Vickers hardness, brinell hardness, rockwell hardness, Rockwell surface hardness, Shore hardness. The standard also addresses information on surface preparation, sample Film thickness, surface effects, and Rockwell surface hardness testing recommendations for surface hardened parts. Due to differences in material size, mass, composition, and heat treatment methods, these conversion values can only provide approximate relationships. For applications that require more precise conversion, special conversion values should be developed for each specific steel composition, heat treatment, and part.
