    Apr 24, 2013 · 4130 is popular for bicycle frames (and aircraft frames) primarily because it doesn't demand heat treating post-welding. You can also get work hardening stress from bending. This 450-500° heating would relieve some of the bending stress but I'd guess a 7° bend introduced next to no stress.Some results are removed in response to a notice of local law requirement.
