Today, hardness testing is one of the most widely used methods in mechanical materials testing, especially for metals. On the one hand, this test method can be used to find qualitative relations to other material properties (e.g., strength, stiffness, density) or to the material behavior under certain stresses (e.g., abrasion . Cary, I received my new Lee hardness tester from Midway a couple days ago and played with it last night until my hands started to cramp. While the scope is a frustrating little device I feel I got a good idea of the hardness of my current batch of 30-180FN (approx. BHN 16) at 189.6 to 190.1 grains naked.
