Metal Material Technology For Ships: 10 Trends

"High" - ship hull steel is still developing towards high performance.

1. High performance is still the main development direction pursued, focusing on improving the overall performance of steel, including strength, plasticity, toughness, explosion resistance, brittle damage resistance, seawater corrosion resistance, fatigue resistance, etc.

2. Pay great attention to the research on process performance such as hot and cold processing and welding, and regard improving the process performance of structural steel as an important development direction in the future.

3. Pay attention to the research and improvement of theories and methods of high-strength structural steel formula design, preparation and application technology.

4. While focusing on high-performance development, pursue low-cost economic performance, etc.

"Titanium" - the research, development, promotion and application of high-performance titanium alloys are imperative

1. While continuing to improve or maintain the existing characteristics of titanium alloys, reducing the manufacturing costs of titanium alloys and their products should be an important direction for future development.

2. Conducting technical research on titanium alloy welding and manufacturing (bending, forming, etc.) processes that are convenient, safe, and reliable for construction is another important direction for future development.

3. Focus on further promoting the application of titanium alloys and their products in ship development.

4. Further improve the titanium alloy material system, continue to develop and expand marine titanium alloy product series, etc.

Open up new areas of application of inorganic materials in ship equipment

1. Carry out research on the working performance and corrosion rules of inorganic materials in complex marine environments, improve environmental adaptability, and improve special properties such as fire prevention, thermal insulation, vibration absorption, and anti-corrosion.

2. Carry out research on the preparation, production and application technology of high-strength lightweight marine concrete, and further promote the development and application of similar marine structures, such as offshore concrete drilling platforms, storage and transportation platforms, barges, floating docks, and crane ships. and other engineering ships.

3. Develop ship interior decoration materials with excellent comprehensive properties (such as craftsmanship, thermal insulation, fire prevention, anti-corrosion, and economy).
