Drawn Over Mandrel (DOM) Round Mechanical Tubing is a cold drawn 1020 / 1026 electric resistance welded tube with all the flash removed prior to cold drawing. In comparison to other tubing, DOM round tubing is produced to more exact OD and ID tolerances, and has the highest weld strength possible.
Benefits of Drawn Over Mandrel (DOM) Round Mechanical Tubing:
Applications: Hydraulic Cylinders, Axles, High Speed Shafts, Barrels, Bearings, Spacers, and many other machined tubular parts.
