Round Tube

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

Meets AMS-T-6736. Stocked in 17 to 24 foot random lengths; cut pieces available.

A.E.D. Stenciled 4130 Chrome Moly Tubes (SKU #'s ending with AED)

We stock over 40 sizes of 4130 Chrome Moly, produced by Webco Industries, specifically for our needs, stenciled with A.E.D Motorsport Products. Over the years we have adjusted the manufacturing of our tubes to offer benefits specific to its application. We require greater dimensional consistency for ease of use and fabrication, improved mechanical properties for fatigue and impact toughness and surface critical production processes to improve weldability and finished appearance.

While A.E.D. is not the only supplier of 4130 tubes, nor is Webco the only manufacture of 4130 tubes, A.E.D. is the only distributor to subject our specific materials to the rigors of race car crash testing both on the track and in true automotive test labs. (Check out this Sprint Car Drop Test) Over the years we have learned what to look for in a quality tube with respect to the review of damages and behavior of these tubes throughout a number of structural test.

We don’t specifically release our aim to production requirements but all tubes are produced to the AMS 6736 B specification with much greater care than required. A.E.D. also visits Webco Industries on a regular basis to meet with engineers to discuss current material characteristics, findings from crash and fabrication reviews and look towards what the next improvements might be. In fact Webco has even hosted guests from SFI to better educate those within safety aspects of racing as to the manufacturing process and values and limitations in our materials of choice for race car manufacturing.

Over the years we have seen a number of mills producing 4130 specified tubes. Many of which we do not feel confident in selling. We have maintained over the years that we sell only the best tube from the most reputable mills – our mills of choice, Webco, Plymouth and Benteler. These are the mills that place the most care in production of safety critical tubes for racing.

Why A.E.D. Chrome Moly Tube? Simple – because we care about our customers and their customers.
