Hello all, I've got a HR-150A (Chinese clone) of a Rockwell hardness tester. Works good with both C and B scales. My question, what would be required for testing lead BHN hardness? OR - is it even possible? It does have a 60 Kg setting for the weight as well as the normal 100 and 150 Kg setting.
I suspect a person could use the 60 Kg weight and a larger ball for the penetrator (1/8"? larger?) and do some testing to determine settings on dial for BHN ranges. I'm just wondering if anyone has already done this.
