Corten steel is a type of alloy steel made by adding cobalt, nickel, and chromium to iron ore. Among other industries, it is used in construction and manufacturing.
Mild steel is an alloy steel with a lower softening point than corten steel, but a higher softening point than mild carbon steel. Applications include automotive parts, industrial machinery, and welding equipment.
Corten steel is becoming increasingly popular among roll-formed product manufacturers. Its unique appearance and naturally oxidizing finish make it highly desirable for architectural projects.
Known as "low carbon steel" in addition to mild steel, low carbon steel has a very low carbon content compared to other carbon steel. Mild steel is usually composed of 0.05% to 0.25% carbon.
