Introduction
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.

Application
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.
Benefits
How Does the Cold Drawn Process Work?
C1018 has such high workability to begin with that this does not have significant negative effects.
How Is C1018 Used?
Any application requiring steel of no great strength can be handled by C1018, and parts that need threading, drilling, punching, or similar forms of machining are often made from this material.
The high workability of C1018 also means it is easy to weld and cut. It can be welded by most known welding processes and produces very high quality welds and joints.
