Great service as usual. Fantastic freight service. Somehow I got 2 pieces 2ft long instead of 1.

Hard to find this material where I live. Aircraft Spruce sent this out fast, at a reasonable price and shipping through the U.S. Mail saved me a lot of money. Tubing is to spec and in perfect condition when received.

I had a very unique repair to make. So nice to have the exact size (both inside diameter and wall thickness) of tubing I needed. Thank you for such a large selection.

I ordered 1 x.0.65 cro-moly for a bicycle that I am building I needed front fork material.It arrived at my house in a timely manor. The packaging was very good and the steel was very clean with just alittle mill finish. I ordered a 7 foot length and had just enough of it. I wanted to order an 8 foot piece but the shipping cost went crazy with that length.

This tubing is great stuff. Working out just fine. The reason for the four stars is the way it was shipped. Four pieces were cut to length with a chop saw and the ends were not deburrd. The box was opened but all the pieces were still there in good shape. The reason the box got opened was the burs cut through the box. I cut the palm of my hand handling the box. Ordering and service at Aircraft Spruce is really great. Ill will continue to use them in the future.

What can I say, nice piece of tubing. Shipping outrages, cost 50% of the price of the tubing to ship it 100 miles

Q&A

Q: Is your 4130 tubing annealed or normalized?

All of our 4130 steel tubing is condition N, normalized.

Q: Is this tubing true seamless or DOM?

Yes, per the tech data sheet it is seamless. The manufacturing process is Drawn Over Mandrel (DOM). Essentially the answer is that it is both.

Q: Is your 4130 tubing "Made in the USA"?

Yes, this material is manufactured in the USA.

Q: What lengths of 4130 alloy steel round seamless tubing are most economical to ship? Is there a crating charge?

It's best to keep the lengths under 4', but we can ship up to 8' via standard ground transportation within the USA. Essentially, the longer (and heavier) the package, the higher the shipping cost.

Q: What AMS Spec does your 4130 Tubing conform to?

ASTM/A S1906

Q: Can this 4130 steel type be bent and flare using normal flaring tools?

It can be bent but I could not find any documents referring to how well this material can be flared.

Q: What is the tolerance on the diameters of the 4130 ALLOY STEEL ROUND SEAMLESS TUBES?

The tolerance is +/- 10%.

Q: Is this 4130 the same as those used on off road applications(cages)?

Yes, we have many customers in the off-road segment that use this material.
