STEEL

Steel is a metallic alloy formed essentially by iron and carbon, with percentages of carbon varying between 0.008 and 2.11%. It differs from cast iron, which is also an alloy of iron and carbon, but with a carbon content between 2.11% and 6.67%. The fundamental difference between the two is that steel, due to its ductility, is easily deformable by forging, rolling and extrusion, while a cast iron part is manufactured by the casting or machining process.
