It's pretty soft Ed, so doesn't break chips easily. I don't know what chemical process makes it black, but that doesn't seem to hurt the machining. The only thing to be wary of is that it's rolled and has a welded seam. While not an issue on the O.D., the weld is quite prominent inside and can chip tools if they have a brittle, dead sharp edge.
