Not necessarilly. Steel actually flexes more than aluminum, until aluminum wears out. Then it breaks. But you have to go through a lot of fatigue cycles before that happens. But steel doesn't really get weaker with time. But you have to make it beefier to have it have the same strength out of the box as an aluminum stem.
