I completely agree there. Corrosion is and should be a far more
pressing concern that fatigue alone. Very often, failures that
initially appear to have resulted from fatigue are actually more
directly caused by corrosion that reduces the effective cross-
sectional area and causes stress risers that result in local yielding
and accelerated fatigue.

Thanks, Bob K.

Corrosion and fatigue work hand in hand. Corrosion begets fatigue and
fatigue begets corrosion. Together, they can cause mayhem.
