With the development of science and technology and the depletion of terrestrial resources, human development and utilization of the ocean has already been mentioned on the agenda. 

Titanium has excellent corrosion resistance to seawater and is widely used in seawater desalination, shipbuilding, marine thermal energy development and seabed resource exploitation.

As early as in the 1960s, China began to apply research on titanium and titanium alloys in marine and offshore engineering equipment, and has done a lot of work. 

It has basically formed a large number of grades, different performances, and complete specifications. Marine titanium alloy system. 

Due to its unique characteristics, titanium and titanium alloys are uniquely used in marine and offshore equipment applications, and are widely used in nuclear submarines, deep submersibles, atomic icebreakers, hydrofoil vessels, hovercrafts, and minesweepers. And propeller propellers, seawater pipelines, condensers, heat exchangers, etc.
