Select various hardness testers for testing based on material type
1. Quenched and tempered steel The hardness test of quenched and tempered steel mainly uses Rockwell hardness tester HRC scale. If the material is thin and HRC scale is not suitable, HRA scale can be used instead. If the material is thinner, surface Rockwell hardness scales HR15N, HR30N, or HR45N...Read more -
Relationship between Brinell, Rockwell and Vickers hardness units (hardness system)
The most widely used in production is the hardness of press-in method, such as Brinell hardness, Rockwell hardness, Vickers hardness and micro hardness. The obtained hardness value essentially represents the resistance of the metal surface to the plastic deformation caused by the intrusion of for...Read more -
Test method for hardness of heat treated workpiece
Surface heat treatment is divided into two categories: one is surface quenching and tempering heat treatment, and the other is chemical heat treatment. The hardness testing method is as follows: 1. surface quenching and tempering heat treatment Surface quenching and tempering heat treatment is us...Read more -
