ASTM A513 DOM Steel Tubing

Amardeep Steel Center Suppy A513 Type 5 Drawn Over Mandrel Tubing. DOM Steel Tube is made from uniformly high grade C1020 carbon steel strip that is shaped and electric resistance welded into its basic shape. After annealing to establish a homogeneous grain structure throughout, the tube is cold pulled over a mandrel to provide the following benefits: uniform concentricity around the central axis, improved ovality, closer tolerances, denser surface, uniform wall thickness, and greater physical characteristics. The cold working method works the weld region to produce a sound, dense, and homogeneous structure similar to that of the base metal.


A Dom Tube is not technically a tubing, rather it is the technique by which they are made. DOM, or Drawn Over Mandrel, is a type of metal forming method. This technique begins with an ERW, or electrically welded formed tube. First, the ERW is cold pulled over a die and across mandrel planes. As a result, the die's size and angle will influence features such as Outside Diameter (OD). The Inside Diameter or ID of Drawn Over Mandrel Tubing is determined by the Mandrel or Plug used.

Depending on its application, a DOM Tube's chemical composition could be mild steel or stainless steel. Any alloy's usage in the fabrication of DOM Seamless or Welded Tubes will be determined by the primary qualities required for any application. Using this metal forming method has various advantages. For example, the cold drawing technique gives the stainless steel dom tube a superior surface polish, higher dimensional endurance, and the strongest weld strength possible. After being cold drawn, the mild steel dom tube is subjected to a heat treatment to modify mechanical qualities and improve properties such as machinability and toughness.

Applications of ASTM A513 DOM Tubing

DOM tubing's combination of tight dimensional tolerances, smooth bore finish, and superior weld integrity makes it the default choice wherever standard ERW tube is too imprecise and seamless tube is cost-prohibitive.

Applications & Uses of A513 Dom Tube

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, Bushings, Couplings, Collets, Fittings, Damper Tubes •   Shafts
•   Cylinders •   Axles
•   Conveyor rolls •   Telescoping and push-pull applications
•   Steering columns •   Shift levers
•   Airbag inflators •   Power seat mechanisms, Seat assembly components
•   Engine mounts •   Fuel rails and injection components
•   Motorcycle and snowmobile frames •   Supports and guards
•   Diesel injection components •   Piston pins
•   Torque wrenches •   Extensions and handles
•   Shanks

Frequently Asked Questions

Q1. What is the difference between DOM, ERW, and seamless tubing?

ERW is welded from strip steel. DOM starts as ERW then is cold-drawn over a mandrel for tighter tolerances and a denser weld zone. Seamless has no weld. DOM gives seamless-like precision at lower cost.

Q2. Which grades of ASTM A513 DOM tubing does Amardeep Steel supply?

We supply A513 DOM in grades 1020 and 1026. Grade 1026 offers higher tensile strength for hydraulic cylinders. Both are available in custom OD, wall thickness, and cut length per your drawing.

Q3. What dimensional tolerances are held on A513 DOM tube OD and wall thickness?

DOM tube typically holds OD tolerance of ±0.005 in and wall tolerance of ±10%. Concentricity and ovality are significantly better than standard ERW. Tighter tolerances available on request for precision bore applications.

Q4. For which end-use industries is ASTM A513 DOM tubing most commonly specified?

Primary markets are automotive driveshafts, hydraulic and pneumatic cylinder barrels, motorsport roll cages, precision shafting, and mechanical structural assemblies requiring tighter tolerances than standard structural tube.
