Overview

Titanium is immune to seawater corrosion, making it the ideal material for naval vessels, deep-sea submersibles, offshore platforms, and desalination plants.

BAOTI supplies titanium plates, tubes, forgings, and fittings for critical marine applications where decades of maintenance-free service life is required.

Our marine-grade titanium products are certified by ABS, DNV, Lloyd's Register, and Bureau Veritas for use in ship classification and offshore structural applications.

Frequently Asked Questions

Why is titanium preferred over stainless steel for seawater?

Titanium is completely immune to seawater pitting and crevice corrosion at all temperatures, while stainless steels suffer pitting above 25°C. Titanium also has zero biofouling attachment rate.

What ship classification approvals do you hold?

Our titanium products are approved by ABS, DNV GL, Lloyd's Register, Bureau Veritas, and CCS for use in classified naval and commercial marine vessels.

What is the expected service life of titanium in seawater?

Titanium components in seawater service routinely achieve 40+ years with zero maintenance. Unlike copper-nickel or stainless steel, titanium does not suffer from erosion-corrosion even at high flow velocities.

Can titanium be used in deep-sea pressure vessels?

Yes, titanium's excellent strength-to-weight ratio makes it ideal for deep-sea applications. Ti-6Al-4V is used for manned submersible pressure hulls rated to 11,000m (full ocean depth).

Is titanium cost-effective compared to super duplex stainless steel?

While titanium has a higher initial material cost, its 40+ year zero-maintenance life, zero corrosion allowance, and thinner wall requirements often result in lower total lifecycle cost than super duplex for seawater systems.
