C1018 Cold Finish Round Bar

C1018 Cold Finish Round Bar


C1018 Cold Finish Round, is a rolled steel product with close dimensional accuracy, smooth surface finish, and increased mechanical properties and machinability. C1018 Cold Finish Round is a general purpose low carbon steel with good case hardening qualities and is especially suited for cold forming and bending. 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.

  • Specifications: ASTM A108-07(ASTM A108 -07 Standard Specification for Steel Bar, Carbon and Alloy, Cold-Finished.)
  • AKA: Cold Roll Round, CRS Round, CF Round
  • Alloy: 1018
  • Characteristics: Oiled surface, smooth dark grey finish. Accurate dimensions throughout length.
  • Workability: Easy to Weld, Cut, Form and Machine.
  • Mechanical Properties: Brinell = 126, Tensile = 64,000 +/-,  Yield = 54,000 +/-

Alloy 1018 is the most commonly available of the cold-rolled steels. It is generally available in round rod, square bar, and rectangle bar. It has a good combination of all of the typical traits of steel - strength, some ductility, and comparative ease of machining. Chemically, it is very similar to A36 Hot Rolled steel, but the cold rolling process creates a better surface finish and better properties.


Designed for close tolerance. Shafts, Hinges, Dowels. Cold drawing also increases torsional strength, surface hardness and wear resistance. 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.
