First, sloppy work by the service dept. They should have removed first, then sent back with reg.
Second, stainless would not have corroded from your use in the manner you described.
I would agree with the assessment of nickel coated brass, with the nickel heavily corroded by some cleaning process and the brass showing from beneath.
Nickel coated brass is a poor choice for salt water. Ordinary brass holds up much better. Maintain as stated in an earlier posting. Stainless steel is even better, but a bit more expensive.
Ospho, as referenced earlier is a mixture of phosphoric acid and sodium dichromate, and used as a rust inhibitor coating. It turns iron oxide (rust) into inert iron phosphate. I know nothing about servicing regs, but cannot see how this stuff has any applicability, unless someone tried to use it to clean up the snap. Really don't know what it would do to nickel.

From the color I'd say that is corrosion. What you probaby have is a plated bolt snap and not stainless steel. Nickel and cadmium are pretty common materials for plating. From the dark color I'd guess cadmium. The acids (and sometime bases) used for ultrasonic cleaning will accelerate the corriosion process.
Ordered another pile of bolt snaps from Reef Scuba and will be replacing any questionable ones... it's a minor annoyance, was more curious than anything.
I noticed last year that some I picked up from the dive shop have not been wearing very well at all; this could be one of them.
