1018 low-carbon steel (mild steel)

1018 low-carbon steel (mild steel)

Short Description:

1018 cold rolled steel is a general purpose low carbon steel with good case hardening qualities. It has higher manganese content than other low carbon grades, such as 1020. Due to the higher manganese content, 1018 is best used for carburized parts because 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 machine turned, rather than drawn, then polished.  1018 is avail...
