Russia is an international leader in the research and manufacture of titanium alloy submarines. It is also the first country to build a pressure-resistant shell with titanium alloy. During peak periods, the annual output of titanium alloy plates and tubes for submarines is as high as 10,000 tons, accounting for 1/3 to 1/2 of the annual output of titanium alloy processed materials. Titanium plates for submarine heat exchangers require good thermal conductivity. The shell material is required to have good toughness to resist the shock wave caused by the bomb explosion. The titanium plate (thick plate) for submarine shells is produced in St. Petersburg, and the ingots are provided by the Upper Salda Metallurgical Production Joint Company. In terms of the development level of the titanium industry and the scale of the use of titanium plates and wires in the shipbuilding industry, Russia is far ahead of all other countries in the world. As Russia is ahead of competitors such as the United States in the field of ship material research, its scholars have called on the government to formulate a recent shipbuilding plan to avoid losing its leading position and the development potential it has formed, while ensuring that the Russian Navy will continue to lead in the 21st century In other countries.
Since the 1960s, Russia has developed four generations of nuclear submarines. The world ’s first K162 all-titanium nuclear submarine was launched in December 1968 and has been in operation for more than 30 years. Environmental assessment has never happened. Russia built the first "ALFA" class nuclear submarine in 1970 and continued to build six more in the 1970s and 1980s. Each one used titanium rods, titanium wires, and titanium plates for about 3,000 tons. The maximum dive depth was 914m, which is light and fast.
In the 1980s, six "Typhoon" class ballistic missile nuclear submarines with titanium rods, titanium wires and titanium plates of 9000 tons were manufactured. The first "Typhoon" class nuclear submarine was built in 1980 and commissioned in 1984. Its underwater displacement is 33800t, and the underwater speed is about 27 knots. The "Typhoon" nuclear submarine is the largest submarine in the world. It has a double-shell structure. The non-pressure-resistant shell is made of high-strength and low-magnetic steel. The pressure-resistant shell is made of titanium alloy. Can carry 20 strategic missiles. The launch time of the sixth Typhoon submarine was at the end of 1989, and the Typhoon series will be retired at the beginning of the 21st century.
