Weathering steel, also called Corten steel, is a high strength low alloy steel that forms a stable, adherent rust patina that slows corrosion, letting unpainted bridges last 120 years.
White cast iron
White cast iron is a hard, brittle cast iron in which all the carbon solidifies as iron carbide rather than graphite, giving a white fracture surface.
Wrought iron
Wrought iron, also known as bar iron, is nearly pure iron with about 0.05 percent carbon and 1 to 2 percent slag worked into a fibrous structure, displaced by steel.
