Titanium and titanium alloys are widely used in nuclear submarines, deep submersives, atomic icebreakers, hydrofoils, hovercraft, minesweeper, propellers, whip antennas, seawater pipelines, condensers, heat exchangers, acoustic devices, fire equipment.
Titanium pressure shell is mainly used in deep sea submersible. Titanium pressure shell is used in different extent at home and abroad. For example, the "Haiya" deep-sea submersible of the United States is equipped with titanium observation module and control module, and can dive to a depth of 6100m. China has also made great achievements in deep-submarine technology. The submersible "Jiaolong", our country's independently designed deep-submarine, has reached more than 5000m. However, only Russia uses a large amount of titanium in large submarines. Its six "Typhoon" nuclear submarines are mainly made of industrial pure titanium, Ti64, Ti64ELI, Ti-6Al-2Nb-1Ta-0.8Mo, Ti-3Al-2.5V, IIT-3B, IIT-7M, etc.
