The best environment for titanium alloy processing is seawater. Because of the metal‘s corrosion resistance, titanium works best in seawater. When titanium is the material of choice, tank corrosion, pitting, stress corrosion cracking, or microbial corrosion in seawater are not a problem.

Titanium applications in the ocean include ship propellers, shipborne heat transfer, pipeline components, ballast components, waste system components, tidal zone protection, shipborne components.
