Heating and annealing is done to form this stuff in other situations. But if you need to heat a piece of annealed, 3/16", .028 to put a single flare on it, you might need a better flare tool. Double flares are not needed and could be problematic if you don't get them done properly.
Never had much luck getting a single flare 3/16 SS brakeline to seal properly, same with a 5/16 or 3/8 SS fuel single flare....I've tried it in the past with various flaring tools.....double always seem the way to go
