Abstract: With the improvement of the requirements for corrosion resistance and high reliability of ships, the demand for titanium materials with outstanding corrosion resistance is becoming more and more urgent, but the high cost has always been one of the important factors restricting the extensive application of titanium and titanium alloys in ship domain. Therefore, a large number of studies have been carried out on the low cost technology of titanium at home and abroad, and some research findings have been applied. However, most of the relevant findings are not systematic. Here is systematically introduced the low cost technology of marine titanium in the USA from the aspects of material manufacturing and application, which will provide a systematic low cost technical reference for the application of titanium materials in the field of marine seawater pipeline.
