| Categories: | MetalFerrous MetalCarbon SteelAISI 1000 Series SteelLow Carbon Steel |
| Material Notes: | Supplied as killed, semikilled, rimmed, and capped steel. Good weldability, relatively soft and strengthen with cold work during forming or drawing. Widely used in cold forming operations such as heading, upsetting, and extrusion. Used in the as-rolled condition as bar, shapes, sheet, and strip. |
