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).
