Using 316 stainless steel would not be a wise decision in a seawater environment. Chlorides lead to stress corrosion cracking (SCC) http://en.wikipedia.org/wiki/Stress_corrosion_cracking in austenitic stainless steel and types 304 and 316 are especially susceptible to SCC. You could try a higher alloy such as 310 or 314, but are better off staying away from austenitic stainless steel.
