Mild Steel Flat Bar Cold Rolled 1018 is a flat, rectangular shaped bar of cold rolled 1018 Mild Steel.
C1018 is a general purpose low carbon steel with good case hardening qualities.
It has a higher manganese content than certain other low carbon grades, such as 1020.
Cold Rolled C1018 is better steel for carburized parts, since it produces a harder and more uniform case.
Due to size limitations of the cold drawing process, large diameter bars are generally turned and polished. The hot roll rounds are usually machine turned, rather than drawn, then abrasively polished.
Due to its versatility Cold Rolled C1018 has a larger size selection than other grades.
