A magnet doesn't attract 316L. (sometimes, you might get a very slight pull, depending on how strong your magnet is)
316L has less ferrous in it than 304/308 grades.
Sorry but you are mistaken. 304 is not magnetic. 430 is magnetic. Neither 304 or 316 SS is magnetic. I was at the stainless suplier recently and they admit that in a scrap bin there is no way to tell the difference.

2008 Nissan Frontier 4X4 Nismo. 12 MPG baseline with my normal commute and heavy stop and go daily driving. Generator installed and working on 3/29/2009
Up to 14.5 MPG with no enhancers. Still testing the effects of lots of HHO and no electronic enhancers.
