AviationNASATechnologyAn iron-base alloy usually containing carbon and other alloying elements. In carbon steel and low-alloy steel, the maximum carbon content is about 2.0%; in high-alloy steel, about 2.5%. The dividing line between low-alloy and high-alloy steels is generally regarded as the 5% level of total metallic alloying elements. Steel is differentiated from two general classes of iron, namely, cast-irons, which have high carbon concentrations, and relatively pure irons, which have low carbon concentrations.
