Grade 1018 Cold Roll Hex Bar
1018 Cold Finish Hexagon Bar is a low carbon steel known for its good case hardening capabilities and excellent cold formability. Its hexagonal shape provides multiple gripping surfaces, making it a reliable choice for fasteners, shafts, and other precision-machined components.
1018 Cold Rolled Steel is available in a wide range of shapes—including rounds, flats, squares, and hexagons—offering flexibility for machining, structural, and industrial applications that require high accuracy and smooth finishes.
C1018 Cold Finished Hexagon Bar, also referred to as CRS Hex or Cold Roll Hex Bar, is manufactured with tight dimensional tolerances and a smooth, refined surface. It is ideal for applications requiring consistent machinability and clean surface quality.
Cold finished steel hexagons offer enhanced mechanical properties compared to hot rolled alternatives, including higher tensile and yield strength, more precise sizing, and improved surface smoothness. These attributes make them a top choice in manufacturing and precision engineering.

Specifications
AISI 1018; ASTM A108; UNS G10180.
Surface Finish
Smooth, Oily Finish; Sharp Corners.
Heat Treatment
Can be carburized and heat treated for case hardening.
Carburizing at 1650°-1700°F, quenching, and tempering at 300°-350°F results in a hard case and tough core.
