Low magnetic or no magnetic steel can play a very good effect on ship stealth. Non-magnetic steel is a kind of functional material, which is widely used in ships and other equipment. Titanium alloy has the characteristics of high strength, light weight, corrosion resistance, non-magnetic, etc., which is very suitable for use on ships, and has long been concerned by countries. In particular, the Soviet Union successfully used titanium alloy for submarine construction and made remarkable achievements. China has also made great achievements in the research of non-magnetic steel, such as a low-magnetic steel has been successfully developed and used in minesweesweeping boat shell, submarine magnetic diameter wall and degaussing dock structure.
