The research and application of Chinese marine titanium alloy began in the 1960s. After decades of development, a relatively complete marine titanium alloy system has been formed, which can meet the requirements of different strength levels of ships, submarines and deep submersibles. Applications include hull structures, propulsion systems, power systems, electronic information systems, auxiliary systems, and special equipment. According to the yield strength grade, the yield strength is below 490 MPa for low-strength titanium alloy, which has excellent plasticity; 490-790 MPa is medium-strength titanium alloy, higher than 790 MPa is high-strength titanium alloy, mainly used in ship power engineering. Heat resistant and corrosion resistant parts and marine special machinery.
