Iron carbon content from 0.6 to 2.0 percent when it became a high hardness can be prepared sword and die like a high-carbon steel. Low, medium and high carbon steels together called "carbon steel." If the iron content of more than 2.0% of carbon becomes hard and brittle cast iron pot can, radiators, pig iron a plow. Usually pig iron carbon content of 3.5% -5.5%. So the difference between pure iron, steel and cast iron main different is that the carbon content. Pure iron is a steel, its chemical composition is mainly iron content in 99.50% -99.90%, the carbon content of 0.04% or less, the other elements, the less the better. Because it is actually not a real pure iron, so called it A near-iron steel industrial iron. General industrial iron special soft texture, toughness particularly large, good electromagnetic properties.
