[b]Unknown Material for Piping[/b]
(OP)
We found some piping have a very good corrosion protection in seawater. So we chase the source but fail. then we take some sample to test, the result is:
Carbon 0.04 Silicon 0.34 Manganese 0.77 Sulphur 0.006 Nickel 11.5 Chromium 17.3 Molybdenum 2.15 Copper 0.27
Any expert or specialist can tell me what is it?

You should check the Nitrogen content also, it may be 316LN.

Corrosion never sleeps, but it can be managed.
