  The International Marine Engineering Organization recently released a new standard for titanium alloy pressure hulls, which sets innovative requirements specifically for the manufacturing of 10,000-meter-class manned submersibles. The new standard requires the use of integral precision casting technology to replace traditional welding structures, a change aimed at improving the performance and safety of pressure hulls.

  Titanium alloys, due to their lightweight, high-strength, excellent corrosion resistance, and non-magnetic properties, occupy an important position in the manufacture of pressure hulls for deep-sea submersibles and submarines. Integral precision casting technology ensures that titanium alloy pressure hulls have higher precision and more complex shape manufacturing capabilities, while reducing potential defects caused by welding, thereby improving the overall structural strength and reliability.

  The implementation of the new standard means that the manufacture of 10,000-meter-class manned submersibles will require stricter requirements for materials, processes, and quality control. Integral precision casting technology not only meets these requirements but also promises to further improve the submersible's payload and space utilization while reducing manufacturing and maintenance costs.

  The release of this new standard will undoubtedly promote the development of deep-sea diving technology and the marine engineering field, providing safer and more reliable equipment support for exploring deep-sea resources and conducting scientific research. With continuous technological advancements and innovation, the performance of future deep-sea submersibles and submarines will be further enhanced, and humanity's exploration of the deep sea will become even more determined and powerful.
