As a lightweight, high strength, excellent corrosion resistance structural materials, titanium can significantly improve the technical and tactical performance of ships equipment, and enhance life-time security capabilities. Currently, titanium alloy and its manufacture technologies for ships using are mainly concentrated in Russia, the United States, France, Japan, China etc.. Russia, the United States and France have made a remarkable progress in titanium research and applications for warships, and the Japan is well know by titanium applications in civil ships. Literature shows that titanium and titanium alloys are mainly used for shell, heat exchanger, condensers, nuclear reactors shell as well as piping systems. Titanium and titanium alloy used for ships will continue to expand in the future, and some new advanced processes and technologies have be pay much more attention in order to reducing the cost of titanium parts manufactures. In recent years, Chinese titanium industry have made a great development, and titanium manufacture processes and forming technologies as well as its equipment levels have greatly improved, and also the cost of titanium alloy has dropped to historic lowest point, that makes the massive application of titanium alloy in ship meet a great opportunity. We should pay fully attentions to research and development of titanium alloy, which called “Marine metal”, and try to give a great support to the safety, reliability and security of the ships during its whole life.
