Shop our online metal selection of Round Chromoly Tubing

We offer a large selection of premium quality round chromoly tubing, 4130 alloy heat-treated to condition N (Normalized). This material meets or exceeds the MIL T 6736 B spec and is often referred to by several different names: chromemoly, chrome alloy, Promoly or simply 4130 tube.

Our Chromoly tubing selection combined with all of our other offerings, is an example of why the Chassis Shop leads the way in servicing you with all your fabrication needs in one call.

Available in several pre-cut lengths for easy and affordable online metal ordering.

Tips for Cost Savings on Tubing Shipments:

If you can use pieces 48 inches or shorter, you will save money on tubing shipping costs.

We recommend ordering tubing in shorter lengths whenever possible and we do offer FREE Shipping to qualifying orders with tubing 48 inches long or shorter.

Tubing over 48 inches long does cost more to ship due to carriers' additional "oversized length" penalties.

Why pay a premium for shipping and then cut the tubing shorter after you receive it?

If you can use 48 inch lengths (or less), it makes more sense to place your order with a pre-cut mindset versus purchasing long lengths.

We offer Chromoly Tubing competitively priced in convenient pre-cut 1 foot increments - up to 90 inches long (the maximum allowable length we can ship you thru most carriers).

It's no problem if you need lengths over 48 inches long for your project, order it that way. To help you with shipping costs, we do provide discounted shipping rates.

PRO Tech Tip:

How to Telescope Tubing

For the best fit when telescoping tubing, select 0.058" wall tubing and slide over tubing with a 1/8" smaller outside diameter.

Example: 1-1/8" x .058" fits over 1" outside diameter tubing.

Tubing dimensions:

Questions and Answers

Is 4130N Chromoly Steel stronger than Mild Steel?

Yes. 4130N Chromoly steel has a significantly higher tensile strength than mild steel, making it a preferred material for high-stress components. Ideal for fabrication of suspension, linkage components, and applications where maximum strength-to-weight ratio is required.

Is 4130N Chromoly Steel lighter than Mild Steel?

The two materials are equal in weight when comparing the exact same thicknesses. Depending on the design and strength requirement, Chromoly Steel in a thinner thickness is often the choice over Mild Steel - resulting in weight savings.

Can I weld Mild Steel to Chromoly Steel?

Yes, it is a very common practice. Mild Steel and 4130N Chromoly Steel can be welded together using the proper welding process and the correct filler rod.

Should I sand off the surface scale of metal before welding?

Yes, it is always a good practice to clean any material in the areas to be welded to reduce the potential introduction of impurities from affecting the final strength of the weld.

Do I need to normalize a component or chassis made of 4130N Chromoly Steel after welding?

Some applications may require normalizing while others may not. This is a complex topic and can't be adequately addressed in a short paragraph. Please call our tech team at 800-530-9494 to discuss your specific project.

How do I telescope or slip-fit tubing?

For the best fit when telescoping tubing, select 0.058" wall tubing and slide over tubing with a 1/8" smaller outside diameter (O.D.).

Example: 1-1/8" x .058" tubing fits over 1" O.D. tubing
