As has been pointed out elsewhere they should be called stain-resisting, but its a bit too late to get rid of the more impressive 'stainless' tag. Commonly used grades range from AISI 430 type (Werkstoff 1.4016) with around 18% chromium and no nickel, to the stuff cutlery is made of ie AISI 304 type (Werkstoff 1.4301) containing the classic 18% Cr and 8% nickel, to much more resistant AISI 316  type (Werkstoff 1.4401) which adds some molybdenum to the mix for additional resistance to corrosion. Plus there are many other grades and special compositions for special applications.Lee</blockquote>
