Actually... stainless steel IS ferrous. Ferrous metals are anything that use iron (Periodic talbe Fe, latin work Ferium), and since stainles steel is steel, which is iron with 1.2-3.6% carbon added, stainless steel and all steels for that matter are ferrous metals. Stainless steel just has an additianl 1-1.8% Chromium added to increase the metals resilience to corrosion. As for the non-magnetic properties... I really wasn't aware of this and I'll actually test this on some SS and find out why it is not magnetic. Sorry for the rant but mechanical engineering has made me very touchy when people make minor mistakes :N .
