I've had strings pop on me as I was lowering them to try to break that corrosion bond. "I didn't break it, but I _was_ witness to it's demise..." If the tension of the string is at 25-60% of breaking strength when it is at pitch, you really have to go out of your way to break it. Next time you have a few spare minutes, a victim piano and your stringing supply all together in one place, try breaking a string (plain wire, please...). Play it while you are cranking up the tension. You'll be amazed how high it is before it starts to fail (plastic deformation) and finally breaks.
