Hardness Testing is a "virtually" non-destructive test that provides the engineer and metallurgist with information on the materials tensile strength, wear, resistance, etc. There are three primary testing methods: Brinell, Rockwell and Vickers. They vary in the size, indenter, applied load and whether the size or depth of impression is used to determine the materials hardness. NDT Supply offers all methods in both new and reconditioned hardness testers.
