Steel Drawn-Over-Mandrel

A513 DOM Round Steel Tube is a precision-engineered welded mechanical tube with the internal weld seam completely removed, producing a clean and smooth internal surface. This design improves flow characteristics and makes it ideal for hydraulic and mechanical applications requiring seamless-like performance.
DOM (Drawn Over Mandrel) Round Steel Tube undergoes a cold drawing process over a mandrel, resulting in superior dimensional accuracy, tighter tolerances, and exceptionally smooth interior and exterior finishes. This makes it highly suitable for critical applications in the automotive and aerospace sectors.
DOM tubing is a high-performance welded tube where the weld flash is completely removed, offering the structural advantages of a seamless tube. It delivers exceptional strength, roundness, and consistency, making it a reliable choice for high-precision engineering and load-bearing components.
Drawn Over Mandrel (DOM) tubing is known for its strength, durability, and corrosion resistance. With extremely tight dimensional tolerances and smooth surfaces, it is widely used in shafts, axles, and mechanical assemblies that require high structural integrity and precision.
DOM tubing is the preferred solution in automotive, construction, and industrial environments where high-strength tubing is essential. Its superior mechanical properties and clean finish allow it to perform reliably under pressure, vibration, and structural loads.

A513 DOM Round Steel Tube, Drawn Over Mandrel Tubing for Precision Mechanical Applications
Specifications
ASTM A513 Type 5 (1020/1026)
Finish: Blue / Gray, slightly grainy
Finish: Blue / Gray, slightly grainy
Additional Notes
If a more economical round steel tube is needed for structural applications, consider HREW Welded Round Steel Tube.
Stock lengths up to 8ft may vary +/- 1/2"; 10ft lengths may vary up to 1ft +/-; 20ft mill lengths are random and may vary up to 3ft +/-.
Grade 1020 is most common, but depending on outside dimension and wall thickness, tubing may also be Grade 1026 or 520.
