C1018 Cold Finish Hexagon

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

1018 Steel is the most commonly available of the cold-rolled steels. 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. 1018 Steel is the most commonly available of the cold-rolled steels.

Characteristics: Oiled surface, smooth dark grey finish. Sharp or defined edges. Accurate dimensions throughout length.

1018 is a free machining grade and is among the most commonly available grades in the world. It is widely available in cold finished rounds, squares, flat bar and hexagons. Despite its unimpressive mechanical properties, the alloy is easily formed, machined, welded and fabricated. Due to its higher Mn content, it can, in thin sections, be hardened to Rc 42. The alloy is  often employed in high volume screw machine part applications, in shafts, spindles, pins, rods, sprocket assemblies and an incredibly wide variety of component parts. Machinability is rated at 62% of 1112 carbon steel. The alloy can be easily brought to a fine finish, its chips are continuous and hard and it can be machined in all conditions. 1018 can be easily formed in the annealed condition. 1018 has been successfully welded using most all the common practices including gas, resistance, oxyacetylene, and submerged melt welding
