Titanium Alloy Shell Gr5 welded shell For Torpedo

Titanium has strong acid and alkali corrosion resistance, and it will not rust when immersed in seawater for 5 years, while steel will corrode and deteriorate in seawater. Therefore, the outer shell of the ship is made of titanium alloy, and the seawater cannot corrode it. The submarine made can resist both seawater corrosion and deep pressure, and its diving depth is 80% higher than that of stainless steel submarines. At the same time, titanium is non-magnetic and will not be detected by mines, so it has a good anti-monitoring effect. Generally, steel submarines will be easily crushed by water pressure when diving for more than 300m. The diving depth of titanium submarines exceeds 300m not only will it not be crushed, but also can effectively avoid the attack of depth charges, showing the unique charm and excellent performance of "titanium submarines". At present, titanium is an irreplaceable material for ships in the deep sea field. Russia successfully manufactured all-titanium submarines as early as 1968. Since the mid-1960s, Russia has produced 6 to 7 double-layer high-pressure hull "Alpha"-class all-titanium submarines, and each submarine uses 3000t of titanium. In addition, such as "Shark"-class nuclear submarines, multi-purpose 945 and 988 nuclear submarines, etc., their underwater displacement is large, the underwater speed is fast, and the ultimate diving depth can reach 800m. Its pressure-resistant shell is made of titanium alloys. Titanium alloys are also widely used in torpedo launch tanks,Pumps, valves, pipes, propellers, etc. made of titanium alloys on torpedo launch high-pressure gas cylinders and crisis coolers have good results and greatly extend their service life.

Grade:

Ti-6Al-4V
It is a titanium alloy strengthened by heat treatment, which has good weldability and sheet formability and forging properties. Used in the manufacture of jet engine compressor blades, impellers, etc. Others such as landing gear wheels and structural parts, fasteners, brackets, aircraft accessories, frames, stringer structures, pipes, are used in a wide variety of applications.
 

Ti-5Al-2.5Sn
