It creates a condition called hydrogen embrittlement which can cause sudden failure. http://en.wikipedia.org/wiki/Hydrogen_embrittlementDave Evans 52_3100 If you're getting hydrogen embrittlement on your springs from cleaning with acid you should be writing a metallurgical journal paper about it. Granted, I would use the wire brush or wheel or sandblasting instead, but a light cleaning with acid is not enough to cause hydrogen embrittlement to spring steel. | | |
