318LN (1.4462) Duplex Stainless Steel Hollow Structural Sections (HSS) are used in a wide variety of applications due to their unique mechanical properties and corrosion resistance. The following is an overview of their features, benefits and typical applications:

Material composition: – Contains approximately 21-23% Chromium, 4.5-6.5% Nickel and approximately 2.5-3.5% Molybdenum, providing a balance of strength and corrosion resistance.

Mechanical Properties: – High tensile strength (approx. 800-1000 MPa) and yield strength (approx. 450-600 MPa).
– Good ductility and toughness, with effective load-bearing capacity.

Corrosion Resistance: – Excellent resistance to pitting, crevice corrosion and stress corrosion cracking, especially in chloride-rich environments.

Production: – Can be easily manufactured using standard methods, including welding and machining, but requires specific techniques to maintain its performance.

Lightweight: – Hollow profiles are lighter than solid profiles and therefore easier to handle and install.

Strength to weight ratio: – High strength allows for thinner walls, reducing material use while maintaining structural integrity.

Versatility: – Suitable for a wide range of applications in various industries, including construction, marine and chemical processing.

Aesthetic appeal: – Smooth surfaces and clean lines enhance visual appeal, making it suitable for architectural applications.

Enhanced durability: – The combination of strength and corrosion resistance helps extend service life and reduce maintenance requirements.

Building and Architecture: – Structural frames: used in building frames, bridges and other load-bearing structures.
– Handrails and railings: ideal for safety barriers and aesthetic elements in public spaces.

Marine Applications: – Offshore structures: for platforms and supports exposed to sea water and harsh marine conditions.

Chemical Treatment: – Pipes and tanks: suitable for handling corrosive chemicals, ensuring safety and reliability.

Oil and Gas Industry: – Drilling equipment: used for parts requiring high strength and corrosion resistance.

Food and Beverage Industry: – Processing equipment: Due to its ease of cleaning and resistance to corrosion, it is ideally suited for structures requiring high hygiene standards.

Generation: – Heat exchangers: components used in power plants exposed to harsh environments.
