JR, sway bars, anti roll bars, stay bars, most are made from high carbon steel that is an industry standard, as long as the bar is not subjected to more than 30* of deflection, auto manufacturers are even using it on trucks but this is where the trouble can start, high amounts of suspension travel causes the steel to be bent past it's yield strength causing work hardened spots and eventual failure, this is where alloys are superior, hollow sway bars should always be made of alloy materials because without the support in the center the hollow tube is deformed past it's yield strength more quickly (the tube collapses on itself) even with less suspension travel.
