ASTM A513 tubing: manufacturer of ERW and DOM mechanical tubing
For the North American market and for any customer specifying in American standards, the reference for mechanical tubing is ASTM A513. We manufacture electric-resistance-welded (ERW) and DOM tubing conforming to ASTM A513, in small precision diameters.
What the ASTM A513 standard is
ASTM A513 is the American specification for electric-resistance-welded (ERW) carbon and alloy steel mechanical tubing. It is the reference for mechanical tubing in the United States and in markets that work with ASTM specifications, and it organises the product into types according to the manufacturing process and the resulting finish.
What the standard specifies
ASTM A513 defines, by types, the requirements for ERW mechanical tubing: dimensions, tolerances, surface finish, material condition and properties. The types range from tubing as it leaves the weld to DOM (Drawn Over Mandrel), drawn over a mandrel to achieve precision bore and outer surfaces and better mechanical properties.
Which Delmàs range meets ASTM A513
The three ranges correspond to types of ASTM A513, according to the finish and precision required:
| Range | ASTM A513 types | Role |
|---|---|---|
| PREMIUM | T2, T4 | Calibrated finish, surface ready for treatment. |
| OPTIM | T4 | Simultaneous bore/outer control. |
| PRECISE | T5, T6 (DOM) | Precision bore, drawn over a mandrel. |
Beyond the standard: your exact size
ASTM A513 defines the types; your design defines the part. As a manufacturer —not a distributor with a closed catalogue—, we start from your drawing and adjust the size to the hundredth of a millimetre, including sizes that do not exist in the standard catalogue. The standard is the starting point, not the limit.
Market, sectors and applications
A Americanstandard: it is the gateway to the US market and to the automotive customers of the Maghreb and others that specify in ASTM.
- Automotive — mechanical and precision components homologated to ASTM.
- Engineering / Mechanical — shafts, guides and mechanical components.
