N'GENIUS for Marine, Naval & Defence

Enhancing performance where it's needed most.

As military systems become more and more complex, so do the materials used to develop them. It's for this reason that - as governments around the world commit to increased spending on defence - one of the key areas of investment earmarked is research and development into high-performance advanced materials.

Alloys from the N'GENIUS Series™ of High Strength Austenitic Stainless Steels can be used extensively in the marine, naval and defence industries due to their strength, durability, low-temperature toughness and significantly enhanced resistance to corrosion. N'GENIUS Series™ grades can fulfil all these design criteria and in addition are non-magnetic, making them highly adaptable advanced materials for marine, naval and defence applications.

Conventional austenitic stainless steels are often utilised due to their wide availability. However, these grades typically possess low mechanical strength and limited corrosion resistance. This restricts their suitability for applications where specific criteria such as pressure, temperature, weight and corrosive environments are critical factors in the materials selection criteria. Some conventional stainless steels can also be partially magnetic.

Weight savings play a critical role in improving the performance, efficiency, and cost-effectiveness of marine vessels.

As such, reducing structural weight can deliver several key advantages, including:

• Lower fuel consumption - Lighter ships require less energy to move through water, reducing operating costs and emissions
• Increased payload capacity - Weight savings can be reallocated to carry more cargo or equipment without exceeding design limits
• Enhanced speed and range - Reduced drag and improved hydrodynamics enable faster travel and longer distances per fuel load
• Better maneuverability - Lighter vessels respond more efficiently to steering and propulsion inputs, improving control and safety

For submarines, weight reduction is even more critical due to the delicate balance between buoyancy and structural integrity, and mechanical properties of the N'GENIUS Series™ could allow designers to:

• Withstand extreme underwater pressures without compromising hull integrity
• Optimise buoyancy control, improving energy efficiency and stability
• Enhance stealth and speed, thanks to reduced mass and improved propulsion efficiency
• Increase operational depth and safety margins, enabling more versatile mission profiles

Ultimately, weight savings contribute to both the economic and operational efficiency of marine and submarine systems - supporting a more sustainable, agile, and capable future for ocean-going vessels.

The N'GENIUS Series™ contains an infinite number Alloy Types and Variants and possess a unique combination of mechanical and corrosion resistance properties, providing a wide range of advanced material solutions for marine, naval and defence applications.

With significantly enhanced strength, alloys from the N'GENIUS Series™ allow engineers to design structures, piping systems, modules, engineering equipment and specialist products with reduced weight but without compromising on durability or structural integrity. Furthermore, their superior corrosion resistance provides the ultimate defence when components are exposed to seawater, chemicals and other harsh conditions.

For advanced material solutions that can be used in a wide range of service conditions and environments to give extended service life and improved sustainability for marine, naval and defence applications, the N'GENIUS Series™ alloys are without equal.

Performance benefits of N'GENIUS™ alloys for marine, naval & defence sectors:

As such, it is possible for engineers to choose from a wide selection of N'GENIUS™ alloys which have a unique combination of mechanical and corrosion resistance properties and provide significant advantages for all marine, naval and defence project applications.
