Titanium Gr.2: Ideal for Corrosion Resistance and Sustainability at Sea

As carbon neutrality efforts intensify, shipbuilders face rising pressure to adopt eco-friendly materials. The marine industry now prioritizes fuel efficiency, emission reduction, and structural weight savings. At the core of these efforts lies the crucial decision of metal selection.

Titanium Grade 2, a commercially pure titanium (CP Titanium), is emerging as a key material in this transition. It offers exceptional corrosion resistance and a high strength-to-weight ratio, especially in harsh seawater environments. These properties make it ideal for applications in shipbuilding and offshore structures.

Compared to conventional steel, Titanium Gr.2 resists damage from chloride ions and oxidizing agents thanks to its naturally formed oxide film. It remains stable even when fully submerged in seawater, outperforming copper and stainless alloys in long-term durability.


Applications and Life Cycle Advantages of Titanium Gr.2

Titanium Grade 2 plays a vital role in marine systems. It is commonly used in seawater intake pipes, valves, heat exchangers, sea pumps, and piping on ships. In offshore platforms, it is applied in submarine cable protection, wind power structures, and marine instruments.

Its durability allows for longer service life and reduced maintenance, which lowers operating costs. Unlike stainless or copper alloys that corrode rapidly in saltwater, Gr.2 offers decades of stability. This leads to a reduced life cycle cost for marine structures and contributes significantly to carbon reduction goals.

Additionally, Titanium Gr.2 holds long-term recycling value. Dong-A Special Metals actively recovers and processes titanium scrap using precision sorting and smelting. Recycled titanium material plays a key role in reducing Korea’s dependence on raw imports and supports a sustainable resource circulation system.

As marine infrastructure expands globally, the demand for corrosion-resistant, recyclable metals like Titanium Gr.2 continues to grow. Dong-A Special Metals is leading this transition with cutting-edge recycling technology and a commitment to carbon-neutral, cost-effective solutions.
