Are all parts of a 1" threaded headset (specifically Tange Levin) likely to be made of steel?
Everything in a steel Levin is steel, apart from the lock nut O-ring and possibly the bearing cages. If it's an alloy Levin, all bets are off :-)
If you damaged a headset while attending to a seatpost, your workshop technique might need a brush-up
Guessing he had the frame at a forward tilt...
