I was sent a length of material claimed to be 303 SS. The color of the metal doesn't resemble stainless. And it sure doesn't cut like stainless. It faced off fairly easily and turned okay, leaving a beautiful finish with carbide inserts. I was applying oil to the tip of the tool while turning the OD and was still seeing small sparks coming off the tool tip.
I then decided to try and part this mystery steel. Parting blade started off cutting well. Nice, long curly chips. Then stopped cutting. Chewed right thru the blades tip. I'm attaching two pictures, one of the curly chips and one of the end of the stock. The metal has stampings at the end. I'm hoping somebody could give me some clarification on what type of material I have. Also, I did a spark test. The shower of sparks were bright white, no orange or yellow that I could see.
