See Cold Roll Steel Tolerances

Cold Roll Square Tube 1018 offers a good blend of strength, some ductility, ease of welding and machining. 1018, the most popular of the cold-rolled steels, is chemically similar to A36 Hot-Rolled steel, but the finishing process offers superior surface finish and mechanical properties. It is typically used in pins, rods, shafts, spindles, and sprockets.
