Steel (from it. Stahl) is a deformable (ductile) alloy of iron with carbon (and other elements), characterized by eutectoid transformation. The carbon content in steel is not more than 2.14 percent, but not less than 0,022 %. The carbon makes the iron alloys strength and hardness, reducing the ductility and toughness.
