Grade Summary: 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 usually machine turned, rather than drawn, then abrasively polished. Due to its versatility Cold Rolled C1018 has a larger size selection than other grades.
Typical Applications: Used for parts requiring cold forming, such as crimping, swaging or bending.Also used on carburized parts requiring soft core and high surface hardness such as king pins, gears, dogs, etc.
Available products: Round Bar, Rectangular Bar, Square Bar and Hexagon Bar.
