Alloy tube products from Ryerson feature high tensile strength and toughness. Ryerson offers a selection of round 4140 alloy tubing, as well as square and rectangular varieties. Similar to its alloy bar stock counterpart, 4140 round tubing offers hardenability, strength, wear resistance, toughness and ductility and is available in annealed or heat treated conditions. It’s a great option for parts typically made from 4140 bar stock where the middle would otherwise be removed by machining. It comes available in full-lengths or as cut pieces using our tube processing capabilities.
