Corrosion resistant metals/alloys withstanding 1000 hrs of Salt Spray
(OP)
Are there any stainless steels or corrosion resistant metals/alloys that withstand 1000 hours of salt spray testing?

On clean, bold, fine finished samples, 316L does not stain.
But if there is any wet/dry cycling or crevices then all bets are off.
I am looking for a NASA paper where they sprayed stainless samples with acidified salt water twice/day and then let them dry. The samples had crevices and were out doors, but there was a roof over them.
The best I remember the 304, 316, 317 and 2205 all rust stained. The 304 and 316 actually pitted through.
Only the superferritic Sea-Cure and superaustenitic AL-6XN survived unscathed.

Corrosion never sleeps, but it can be managed.
