1018 is a free machining grade and is among the most commonly available grades in the world. Alloy 1018 is easily formed, machined, welded and fabricated. Cold drawn tubing inherently possesses a high strength-to-weight ratio and can be processed to provide a combination of desired characteristics: good surface quality, excellent micro-structure uniformity, good machinability and high tensile properties. Seamless mechanical tubing is produced from solid round billets by rotary piercing and then is rolled in an Assel mill equipped with a no-end-loss unit that permits an extremely broad range of diameter/wall thickness ratios. Tubes are then processed through a multiple-pass sizing reducing mill and a rotary sizer. The 1018 Cold Drawn Seamless Tube listed for sale on this page is Pickled & Oiled and offered in a black, unground state. We additionally offer this material with a ground and polished finish. 1018 Cold Drawn Seamless Tube is the primary tubular steel used in the manufacturing of Race Cars in the NASCAR racing series.
