Grade 1018 Cold Square Bar
1018 Cold Rolled Steel Square Bars feature a smooth, dark grey oiled finish and precise dimensions throughout, making them ideal for applications requiring consistent geometry and a clean appearance. Their refined surface and tight tolerances enhance machinability and reduce post-processing.
1018 is a low carbon steel with excellent case hardening properties and is manufactured for close tolerances. Its balance of machinability and strength makes it a common choice for precision components such as shafts, hinges, dowels, and other custom-machined parts.
C1018 Cold Finish Square is a versatile low carbon steel known for its case hardening capability and ease of cold forming. It is well-suited for brackets, connectors, and parts that undergo bending or forming operations, offering reliable performance with minimal cracking.
C1018 Cold Finished Square, also known as CRS Square or Cold Roll Square Bar, is manufactured with superior dimensional accuracy, tighter tolerances, and a smoother surface finish than hot rolled alternatives. It is a go-to material for machining and fabricating precision tools and parts.
Cold finished steel square bars offer improved mechanical properties over hot finished options, including higher tensile and yield strength, smoother surfaces, and consistent size control. These advantages make them a preferred material in demanding manufacturing and engineering environments.
