I get the use of high carbon steel for roll bars, its heat treatable. You can make a spring from it. But mild steel which has a carbon content of between .16-.25 % of the total mix should not be used for a roll bar.. There is not enough carbon in mild steel to do any heat treating so you cant make a spring out of it.
So when I saw this (below) I was having some issues. Might be a mis-speak, I do it all the time. But you cant make a roll bar (sway bar, anti-roll bar) from mild steel. I dont think anyone does. And if they do they arent making a roll bar. They are just putting a common steel bar in an application that it doesnt belong. I just think it should be clarified so a guy doesnt think he can get some mild steel bar or tube and make up a roll bar. It will bend and break. JR

The arms bolt to the flanges that are welded to the mild steel DOM main bar.
