Submarines like to use titanium alloy as a pressure-resistant shell

In the early days of the struggle for supremacy between the United States and the Soviet union, the Soviet union developed a large number of submarines, especially some later nuclear submarines, in order to cope with the maritime threat posed by the aircraft carrier battle group of the United States. The operational performance was excellent, which greatly enhanced the strategic deterrence capability of the Soviet union underwater. And one of the characteristics of Soviet nuclear submarines was that they liked to use titanium alloy to make pressure-resistant shells. So why? What's the advantage of titanium alloy? In fact, the reason is very simple, since the submarine's compression shell, of course, is to resist pressure.

It is widely known that submarines often go down to a certain depth when performing missions. As the depth increases, the pressure under the water will increase. This is very important to test the pressure resistance of submarines, especially the material of the pressure shell. Titanium alloys, on the other hand, are among the most powerful metals in stiffness and strength properties, and these metals can be added to a submarine to effectively ensure that there is no deformation or fracture at strong water pressure. On the other hand, titanium alloy metal is not only of high strength, but also of special light quality. Therefore, the pressure shell made of titanium alloy can effectively reduce the load of submarine, which is of great help to the speed and voyage of underwater navigation.

In fact, not only the Soviet nuclear submarine USES titanium alloy for its pressure-resistant shell design, but also some deep water detectors will use titanium alloy as the shell. For example, China's deep-manned submersible jiaolong is the case, and the hull of jiaolong is the case.

Ti80 titanium alloy material. This titanium alloy material is further developed in China on the basis of Ti6211 in the United States. It not only has amazing strength, but also has excellent properties in toughness, corrosion resistance and other aspects.
