T303: Type 303 is a free-machining variation of T-304. The addition of sulfur for better machinability makes this a favorite for use in automatic screw machines.
304-304L: The most widely used of the austenitic grades, T-304 offers good corrosion resistance to many chemicals and industrial atmospheres. Generally considered non-magnetic, it can become slightly magnetic when cold-worked. In 304L, the carbon content has been lowered to .03% max. for corrosion resistance at heat affected zones from welding.
316 & 316L:Type 316 is an austenitic chrome nickel steel with superior corrosion resistance to that of other chrome nickel steels. T-316 is generally considered non-magnetic, but can become magnetic when cold worked. In 316L, the carbon content has been lowered to .03% max. for corrosion resistance at heat affected zones from welding.

I started buying from American Metals at the turn of the century and have been very pleased with them, great prices, great service, I can't ask for anything more out of a supplier.
