I started with a piece of 7/8 O.D 4130 chromoly tube. Had them bent to make a pair of bicycle handle bars aprox 30" width and 4" rise. The bars bent the first day about 7 degrees at the first bend. My thoughts are to heat treat again after the bending process. Things Ive read and heard from fellow small time manufacturers, heat up the furnace, home oven in my case, to about 450-500 degrees F. let bake for 20minutes and then dip in motor oil to seal the heat process. This is a final touch to the handlebars before production levels. I need to know if this process can harden the chromoly just enough to hopefully prevent bending again.
thanks,
