What is DOM tubing used for

DOM Steel Tube is produced using uniformly high quality C1020 steel strip and is formed and electric resistance welded into its basic shape.
After annealing to produce a uniform grain structure throughout, the tube is then cold drawn over a mandrel to give it these : uniform concentrically around the central axis, better ovality, closer tolerances, denser surface, uniform wall thickness, and higher physical properties.
The cold working process works the weld area to produce a sound, dense, and homogeneous structure comparable to that of the base metal. The weld line disappears, causing to be virtually seamless. The surface is superior to that of regular seamless , since the material has been cold drawn from strip steel. The hole is straight and concentric with the outside diameter. DOM Steel Tube may be machined, formed, welded, carburized, and subjected to other fabricating techniques that are ordinarily applied to low carbon steel.
The use of DOM Steel Tube gives you a guaranteed micro-inch surface and lower productions costs by reducing or eliminating such operations as boring, honing, and finishing.

DOM Steel Tube can be used for a wide variety of mechanical applications. It may be used either statically or dynamically. Its close tolerances, good finish, and dense structure make it ideal for parts such as bearings, shafts, cylinders, axles, bushings, collets, conveyor rolls, couplings, , telescoping and push-pull applications, steering columns, shift levers, airbag inflators, damper tubes, power seat mechanisms, engine mounts, fuel rails and injection components, motorcycle and snowmobile frames, supports and guards, diesel injection components, piston pins, seat assembly components, torque wrenches, extensions and handles, shanks, etc.
Machinability is rated at 78% of B1112. Average cutting speed 130 ft/min. This grade is easily welded by all welding processes including gas, air, and submerges arc, and the resultant welds and joints are of extremely high quality. Preheat and post-weld heating is generally not necessary.
DOM Steel Tube will respond to any carburizing method and subsequent heat treatments. Case hardening results in a hard case and relatively soft core. Carburize at 1650°-1700°, oil or water quench and temper at 300°. Carburizing depth is typically .060-.070″.
