These bags are a good deal and appreciate them. However, in this purchase there was a heavy cutoff rod of looks like stainless steel - very shiny. Thats OK I guess, but it makes me question if the rest of the tubes/rods/plates are really all 4130 or not. Any thoughts on that? Of course, working on aircraft, this is an important question.

Thank you, the Bargain Bag of 4130 Chrome-Moly tubing is just what I was looking for to use as practice with my TIG welder. I wanted to get some welding time in and work with my tube coping unit for good fit-up.

Nice assortment of sizes, wall thickness. Mostly round with a few square and even some chunks of streamline tubing. Theyre all about a foot long or so, maybe a little less, just right for learning to cut, cope and weld tubing.
