Carbon Steel round bar C20 is an unalloyed low carbon mild steel grade supplied as a hot rolled or bright drawn finish bar. As a low carbon grade, it provides low strength with good machinability and is suitable for welding. Lightly stressed in the form of bolts, fixings, shafts, spacers, hubs, and bushings. Bracketry, linkages, and base plates would be fine to produce using carbon steel EN3.
