30mm OD x 3mm Wall 60" Long 1018 Carbon Steel Round Tube is the most common grade of carbon steel. Round Tube is commonly in a wide variety of applications including structural and manufacturing. It has high strength and good ductility but offers poor corrosion resistance. This product is cut to metric sizing. 1018 is machinable, weldable and is heat treatable. Please allow for +/- 2" length tolerance.
