C1018 Cold Finished Round (CRS Round) represents precision-engineered steel at its finest. Unlike its hot-rolled counterparts, this premium material delivers exceptional dimensional consistency, tighter tolerances, and a silky-smooth surface finish that reduces finishing work. This versatile low-carbon steel offers outstanding case hardening capabilities, allowing for a wear-resistant exterior while maintaining a tough, ductile core. Its balanced carbon content makes it the gold standard for cold forming and bending operations, with minimal spring-back and excellent workability.

1018 cold rolled steel round bars feature a distinctive smooth, dark gray oiled finish that not only enhances aesthetic appeal but also provides initial corrosion protection. These precision-manufactured bars maintain exceptionally tight dimensional consistency throughout their entire length—a crucial factor for applications requiring exacting fits. Meeting the rigorous ASTM A108-07 specification, they deliver the perfect combination of strength, machinability, and dimensional stability for critical components like precision shafts, load-bearing hinges, and alignment dowels.
