304 SS is a hi grade SS and is used in all food processing, kitchens etc, and is in no way magnetic at all.

Stainless steel comes in many grades. 304 is magnetic and borderline stain-less. 18-8 is a step up but the tough stuff to cut is 316 marine stainless. It has molybdenum. Exotic grades have vanadium. Misery is trying to cut chromium nickel vanadium molybdenum stainless steel. I like SCVjeffs answer. I've seen rod glow red as a wheel spun through it rapidly getting smaller. Not the easiest stuff to work with. I believe 316 has a tensile rating equal to a grade 5 fastener.
