DOM tubing is also referred to as ASTM A513 T5 tube and is typically constructed from SAE 1020 or 1026 steel with a chemical composition of carbon, manganese, phosphorous and sulfur. Carbon steel tubing is an economical solution that provides high tensile strength that makes it resistant to breaking under tension. Because of these qualities, even thin tubes formed from A513 steel will show superior strength that performs under demanding of conditions.

A513 T5 Grade DOM 1020/1026 Chemical Composition:

Grades C, max Mn, max P, max S, max
1020 0.17-0.23 0.30-0.60 0.035 0.035
1026 0.22 - 0.28 0.60 - 0.90 0.015 0.005


A513 T5 Grade DOM 1020/1026 Mechanical Property:

Grades Tensil strength (Mpa) Yield strength (Mpa) Elongation % RB
1020 448 379 10 75
1026 490 415 15 85

The durability, reliability and tensile strength of A513 T5 mechanical tubes makes it suitable for a large range of high demand appliance, construction and mechanical applications. Some of the more common uses for DOM mechanical steel tubing include: shafts, cylinders, axles, bushings, collets, conveyor rolls, couplings, fittings, 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.

DOM steel tubes feature several superior mechanical properties and dimensional tolerances that make them an ideal choice for demanding and high precision mechanical applications.


The benefits of using ASTM A513-T5 DOM square tubing include:

  • Easily machined, formed, welded and fabricated
  • Cold finished for a smooth surface finish
  • Superior tensile strength and yield strength
  • Excellent concentricity and dimensional accuracy
  • Possibility for close tolerances during manufacturing
  • Nearly limitless size possibilities
