    The "most" stainless steels are the 300 series  which contain over 16
    percent  chrome and nickel (8-10 percent nickel is common) but are
    mostly iron. This material is austienitic and stainless. Austinitic
    steels are not magnetic. It does not make good knives and other
    grades which are ferritic are used for this and a lot of other lower
    cost "stainless" steel products-- these alloys  contain 12 -30
    percent chrome which make them stainless but do not contain nickel.
    These grades are magnetic. 

    It is iron that makes them steel.
