The composition listed is only for structural shapes, plate, sheet, strip, and welded tubing. Hot-rolled and cold finished bars, semifinished products for forging, wire rods, and seamless tubing have a carbon content of 0.13 - 0.18%. Has better machinability and carburizing characteristics than the more formable extra-low carbon steels. Applications: cold-formed, cold-headed, or forged parts which are low strength with hard, wear resistant surfaces. |
