A513 1020 DOM Tubes
A513 1020 DOM Tubes are highly sought-after for their superior quality, strength, and reliability in a wide range of industrial and engineering applications. DOM stands for “Drawn Over Mandrel,” a manufacturing process that produces tubing with superior mechanical properties, tight tolerances, and a smooth interior finish. This page will provide an in-depth look at the A513 Dom Tube, including its specifications, features, benefits, and common applications.
What is A513 1020 DOM Tubing?
A513 1020 DOM Tubing refers to a type of mechanical steel tubing manufactured using ASTM A513 standards, specifically Type 5, which indicates that the tubing is welded and subsequently drawn over a mandrel. The “1020” in its name denotes the carbon content of the steel, indicating it is a low-carbon steel with excellent machinability and moderate strength.
The DOM (Drawn Over Mandrel) process improves the tubing’s surface finish, mechanical properties, and dimensional accuracy, making it a preferred choice for demanding applications.

Features of A513 1020 DOM Tubing
- High Strength and Durability: The cold drawing process used in manufacturing A513 Drawn Over Mandrel Tubing enhances its strength and toughness.
- Smooth Surface Finish: Both the interior and exterior surfaces of the tubing are smooth, reducing friction and improving compatibility with other components.
- Tight Tolerances: This tubing offers consistent dimensions, ensuring seamless integration into various applications.
- Good Weldability and Machinability: As a low-carbon steel product, A513 Mechanical Tubing Steel is easy to weld and machine.
- Versatile Applications: Its mechanical properties and precision make it suitable for a wide range of uses in industries such as automotive, construction, and manufacturing.
Advantages of A513 1020 DOM Tubing
- Enhanced Mechanical Properties: The cold drawing process imparts greater strength, toughness, and hardness.

Manufacturing Process: Drawn Over Mandrel (DOM)
The A513 DOM Tube is created through the following steps:
- Electric Resistance Welding (ERW): A steel strip is shaped into a round tube and welded along the seam using electric resistance.
- Cold Drawing: The welded tube is drawn through a mandrel and die to refine its dimensions, improve the surface finish, and enhance its mechanical properties.
- Heat Treatment: The tubing undergoes stress relief or annealing processes to achieve the desired mechanical characteristics and reduce residual stress.
This process eliminates the weld seam and produces a product with superior strength and dimensional accuracy compared to standard welded tubing.
