    Probably a good place to look is manufacturer's data sheets for cold rolled
    carbon sheet steel, intended for use in electric machines. When properly
    heat treated, the carbon content is very low.

    A good place to start would be US Steel. Unfortunately, US Steel doesn't
    appear to have their data sheets in pdf form on their website--the most
    descriptive page I could find was <A HREF="http://www.usx.com/corp/ussteel/sheet/cr/index.htm";>
    http://www.usx.com/corp/ussteel/sheet/cr/index.htm</A>
    However, a guy at work gave me a notebook of US Steel data sheets from the
    late 1970's. I scanned a couple of carbon sheet steel B-H curves from these
    data sheets. Using the very cool and free program, WinDIG (see <A HREF="http://www.unige.ch/sciences/chifi/cpb/windig.html";>
    http://www.unige.ch/sciences/chifi/cpb/windig.html</A>), I was able to painlessly
    convert the scans into numerical data and import it as a femm B-H curve. The
    results are in the attached .fem file, in the materials section.

    Note, however, that the US Steel material has been carefully heat treated to
    bring out the best magnetic properties. If you are just machining parts out
    of blocks of steel that aren't heat treated in any particular way (and you
    really care about the specific properties of the material), you'd probably
    want to resort to measuring the B-H curve of a sample of your material (or
    hiring someone to do it).
