We have some equipment which has corroded faster than expected and I wonder if anyone might be able to provide some insight?
Matl: 17-4PH H1150 HRC 28 with a liquid nitride treatment
Exposed to atmosphere on offshore platform in warm climate. Severely pitted/corroded within 4 months.
We have hundreds of these parts out there and several on the same platform without problems. The only thing I can think of (and I'm grasping at straws) is: Could bird droppings in a salt spray, hot & humid environment cause severe corrosion of 17-4PH?
