Corrosion/pitting causes?
(OP)
Hi chaps,
Can anyone explain why this supposedly 316L SS watch bracelet has severve pitting? Also why aren't the outer links not pitted?
Thanks in advance.

RE: Corrosion/pitting causes?
What makes you sure its corrosion pitting- just because its got "pits" doesn't mean that pitting is occurring- could easily be erosion or crevice corrosion. The outer links could easily have trapped water for longer, the inner dry off quickly. I assume this watch has been exposed to standard harsh atmospheric conditions- coastal, industrial perhaps splash but not salt water/ pool water immersion conditions while being worn on the hand.

I would question if these links are 316, they may be 201. In which case even exposure to liquid hand soap ( a few % Cl) could lead to this attack rapidly.
Was there any corrosion product? A rust colored surface film? If not then it may be that most of this pitting existed in the original condition and they buffed it over to hid it. Then moisture would be easily trapped and a small amount of corrosion would then be revealed.

The chap has removed the old gold plate with blasting media hope that helps.
Yes the centre links certainly look a different grade of SS probably cheaper grade maybe?

The bracelet is by Tag Heuer so SHOULD be decent quality.
