31 (1.4562) Stainless steel, known as superduplex stainless steel, is valued for its exceptional strength and corrosion resistance. Below is a detailed overview of its features, advantages and typical applications in hollow structural profiles (HSS).

Material composition: High levels of chromium (24-26%), nickel (6-8%) and molybdenum (3-5%) enhance corrosion resistance, especially in chloride environments.

Mechanical Properties: High tensile strength (approx. 800-1000 MPa) and yield strength (approx. 600-800 MPa).
Good ductility and toughness, making it suitable for structural applications.

Corrosion resistance: Excellent resistance to pitting, crevice corrosion and stress corrosion cracking, especially in harsh environments.

High Strength to Weight Ratio: Allows for lightweight design without sacrificing structural integrity, resulting in easier handling and installation.
Durability: Long service life due to superior corrosion resistance, reducing the need for maintenance and replacement.
Versatility: Suitable for a wide range of applications across a variety of industries, including construction, marine and chemical processing.
Aesthetic appeal: Provides a modern and polished look, making it ideal for architectural and decorative applications.
Fabrication: Easily fabricated using standard techniques such as welding, cutting and machining.

Ocean and offshore structures: Oil and Gas Platforms: Used on offshore drilling and production platforms exposed to seawater.
Marine: Used in marine components requiring high strength and corrosion resistance.

Chemical Processing: Tanks and Pipes: Ideal for handling corrosive chemicals in process plants.
Heat Exchanger: Used in equipment exposed to corrosive liquids and high temperatures.

Building and Architecture: Building Framing: Structural framing used in commercial and industrial buildings.
Architectural Features: Used for decorative elements that require both strength and beauty.

Power generation: Support Structures: Used in power plants to support heavy equipment and structures exposed to harsh conditions.

Food and Beverage Industry: Processing Equipment: Suitable for structural components in food processing and packaging facilities to ensure hygiene and safety.

Infrastructure: Public Structures: Used for railings, canopies and other public infrastructure requiring durability and corrosion resistance.
