Tell me about the finish, it looks as though it were done on a surface grinder with a coarse wheel. It could be just the lighting and the way the photo was made though.
Ken,
I got the material from Kaoma. He said it was a SS strap that's used as an electrical grounding strap, I'm assuming for cell phone towers since he works on them for a living. I've never worked with SS before so I put a magnet to it and it didn't stick and then I did a couple of exploratory drilled holes and was surprised as to how easily it drilled. It almost drilled like it was aluminum and looked like chrome plated aluminum but I'm pretty sure you can't chrome plate aluminum. So I went ahead and started milling them out and it milled easily. I took a file to it to deburr the edges then I knew it must be SS because the file did not take a very good bite out of it. I'm guessing it's 303 SS. Anyway, one side has a brushed finish as seen in the picture and the other side is flat and shinny, like it was chrome plated.
