316 and 409 is magnetic. Or at least when I try to stick a magnet to them they stick unlike 304.
If its 316 or 304, a magnet shouldnt stick to the metal, as far as i know about SS. I tried it with 304 and doesnt stick.
My metalshop called me and they have a semi used plate of 430 SS...
Now they will roll 2 tubes for me so i can do my tests.
its a giant plate, btw. 3 mtr by 1 mtr.........well, i will have lots of 430 left.
Cost me 70 dollars......ai...again a hole in my budget.
