    To say mostly iron and carbon is pretty misleading. The most common grade of steel sheet contains 0.08% carbon. A high carbon spring steel would be 0.95% carbon. The most common grade of stainless steel contains 18% Chromium and 8% nickel and 0.08% maximum carbon. Almost all steel grades and alloys contain more manganese or other trace elements than carbon.

      Isn't your explanation due to grades of steel? I realize there are many materials in all types of steel. I think the question was misleading. It was only taking into account a 'perfect' grade.

      primarily iron & carbon w/trace amounts of elements (depending on composition desired) including or more of the following: manganese, nickel, chromium, boron, titanium, tungsten, cobalt, phosphorus, sulfur, silicon, and a few others most ppl have never/rarely heard of

      whatever manufacturers are able to get away with.

      Since all alloying elements used in specialty steels cost much more than iron, it would be really stupid to add those without a real benefit.
