Titanium is the metal of choice for offshore oil rigs where its corrosion resistance makes the metal ideal for prolonged

exposure to salt water and corrosive substances. Titanium is also used for the cathodic protection of steel in marine environments and underground structures like offshore wind turbines, where it can provide protection for the lifespan of the installation.

Currently, corrosion is one of the chief problems facing the operational life span of naval and merchant vessels; titanium can mitigates these issues, titanium propellers are becoming increasingly common, whilst the office of naval research is exploring the future of titanium hulled vessels.

Titanium alloys are used in a wide variety of military applications due to their excellent strength-to-weight ratio and corrosion resistance. Some of the most common uses include aircraft and missile components, armor plating, and naval vessels. Titanium alloys are also used in body armor, helmets, and ballistic vests. In addition, titanium alloys are used in a variety of land-based military vehicles and submarines.
