Totten Tubes stocks A513-1 as welded mechanical steel tubing and A513-5 DOM mechanical steel tubing in various sizes and shapes. The ASTM A513 specification covers electric-resistance-welded carbon steel tubing for use as mechanical and ornamental tubing.

The ASTM A513 spec information that is most pertinent to our purposes is as follows:

Chemical Requirements

Grade Designation Chemical Composition Limits, %
Carbon Manganese Phosphorus, max Sulfur, max
1010 0.05-0.15 0.30-0.60 0.035 0.035
1015 0.10-0.20 0.30-0.60 0.035 0.035
1020 0.15-0.25 0.30-0.60 0.035 0.035
1026 0.22-0.28 0.60-0.90 0.035 0.035

Materials & Manufacture

A513 mechanical steel tubes shall be manufactured via electric resistance welding, and shall be made from hot- or cold-rolled steel, as specified.

Permissible Variations in Dimensions (Wall Thickness)

Permissible variations in wall thickness for A513-1 steel tubing are ±10% of the nominal wall. Permissible variations in wall thickness for A513-5 DOM are available by request. Contact Totten Tubes for more information.
