An iron-based alloy, malleable in some temperature range as initially cast, containing manganese, usually carbon, and often-other alloying elements. In carbon steel and low alloy steel, the maximum carbon 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 being at 5% metallic alloying elements. Common name for large family of Iron based alloys with Carbon content. Steel is easily malleable after molten stage. See also steel classifications. As used in knife blades, an alloy of iron saturated with carbon, and now often including other elements to foster toughness or stain resistance.
