EN 1.4462, also known as duplex stainless steel grade 2205, is a popular material for square tubing in various industrial applications. This alloy combines the strengths of austenitic and ferritic stainless steels, offering excellent corrosion resistance and mechanical properties.
Square tubes made from EN 1.4462 are prized for their:
Corrosion resistance: They perform well in harsh environments, including marine and chemical processing.
Strength: The duplex structure provides high yield strength, allowing for thinner walls and weight reduction.
Versatility: These tubes are suitable for structural applications, fluid transport, and architectural projects.
Weldability: EN 1.4462 can be easily welded using common techniques.
Cost-effectiveness: Despite initial higher costs, the material's longevity often results in lower life-cycle expenses.
Common applications include offshore oil and gas platforms, desalination plants, and bridge construction. The square shape offers advantages in terms of aesthetics and ease of connection in structural designs.
