Nice going! Its neat to see results like this. Now to play the devils advocate. What if the dent or rock slides on the seam of HREW tubing? VS Seamless DOM?I don't doubt that your steel is stronger but just thought I would ask. Don't worry every piece of prefabbed steel on my truck is from marlin and thanks cause Ive given them a beating!
Thank you for the excellent question. In terms of hardness, I would assume it to be much harder due to the tempering effects during the welding process. I will be doing some other tests in the up coming weeks and will revisit this question when I return to the lab. My hypothesis: The welded region will be harder, but I wonder how the welded region will hold up while it is being deformed. After typing that last sentence I immediately wondered where that seam was during the crush test, so check this out:you'll notice the seam is at the bottom. At first thought I wipe my forehead and say "whew" but as I ponder this more, I bet that due to the increase in hardness near the welded region, perhaps the material will be harder to crush if the seam was at 6' or 3'o-clock? This has definitely raised my curiosity!
This shouldn't even be a factor. This is a common misconception about DOM. Common DOM isn't seamless. It's actually just ERW which is drawn over a madrel in order to flatten out the weld inside the tube in order to obtain symetrical and consistent side wall. My point being that the DOM was also welded, so as far as temper or anything similar, they shoudl be equal. Here's a link that should explain it in much more detail. http://www.pirate4x4.com/forum/showthread.php?t=659544
mspry,Thank you for this information. It only proves more the point that simply having a "DOM" product does not prove it is more dent resistant than a HREW product BigMike
I still say strength is all in the design.
If this was anyone else it would get flagged but to a indifference on this board it wont.
4130 anyone?
im not a lawyer or anything but couldnt you take your test results and open a class action lawsuit for false advertising?
thiss is what happened to mine this weekend out snow wheeling and got caught in the ditch and hit a stump.. didnt even hit hard iv dropped off rocks and beat on this bumper hella good all the time and never any prob... you can see the missing paint in the 3rd pic where it bent right wher the shackle mounts use to be
