Bob,

It isn't cheap ($390), but standard test kits are available. See below:

I received two 7x15 stainless ports today. When I ordered them I was
assured they were 316 ss. So today I thought I would see if a magnet
would stick on one. The magnet stuck. When I called the supplier about
another issue I mentioned that my magnet was sticking to the 316 ss
port. I was told the polishing process was to blame and the 316 had
"picked up a slight magnetic" charge.

Is that true?

Are there simple NDT methods to determine if a stainless alloy is 304
or 316?

Hey man why dont you just get out there in your boat and see if she sinks.
I am not being sarcastic sail the damn thing thats what its for!

Jules, Jules, Jules, ..... you don't understand. If we wanted a boat to
sail, we'd buy one of the many used ones available. It's cheaper and much
faster. We build because we want one done our way and we enjoy the process.

Hey Jules:

Thanks for the advice. Before I go sailing I may want to plug the two
7x15 holes in my cockpit first. Most of us in the northwest tend to
avoid "free commnication with the sea."

Oh, I almost forgot................ GFY.

Jules... listen to Bob...
avoid "free commnication with the sea."
