4130 STREAMLINE TUBE
4130, also known as "Chrome Moly" (short for chromium molybdenum) is a general purpose steel that has been widely used by the motorsports industries for many years. Weldability, fabrication and mild hardenability make it a popular choice in all forms - tube, bar, sheet, and plate.

CUSTOM STREAMLINE TUBE

For several years, A.E.D. has offered the following previously unavailable sizes of custom streamline "aerotube."

They are produced by roll-forming ROUND tubes through a series of rollers and dies.  This process is cold-rolled, and no further processes (such as stress-relieving) are performed afterwards.

The round tubes can be 4130,  Mild Steel, Aluminum, Titanium ("CP" Grade is preferred), or Stainless Steel.

Wall thicknesses can range from .032 - .065, based on availability of round material.

Minimum order is one length of the round material.

There are no tolerances on the finished dimensions. The major and minor are going to be close to the listings, but the type and grade of material are going to affect the finished results, as well as the wall thickness.

There are no material test reports (sometimes referred as "material certifications") available for the finished roll-formed material.  Test reports are available for most of the original round tubes at an additional cost. Be sure to discuss with your sales representative.

NOTES:

The smaller sizes tend to be more in an OVAL shape rather than the STREAMLINE shape.  This is due in part to the smallness of the dimensions and the way the tooling operates.

On sizes above in RED:

We have modified our listing of major and minor dimensions of the following sizes to closer reflect the finished dimensions that have been obtained:

Streamline 0.457 0.270 .375
Streamline 0.635 0.320 .500
Streamline 0.775 0.430 .625
Streamline 1.640 0.730 1.250

None of these custom tubes are kept in stock.

They are produced to order only.

Minimum order is one length of ROUND material.
