1.4410 stainless steel is an excellent choice for hollow structural profiles in water treatment applications. Here are the main features and advantages of using 1.4410 stainless steel hollow structural profiles:

1.4410 (EN 1.4410) is a duplex stainless steel with high chromium (24-26%) and molybdenum (2.5-3.5%) content, providing excellent corrosion resistance.
The material offers excellent resistance to pitting, crevice and stress corrosion cracking, making it ideal for water treatment environments.
1.4410 can withstand exposure to seawater, chlorides, acids and other corrosive chemicals commonly found in water treatment facilities.

1.4410 stainless steel hollow structural profiles have high tensile strength and yield strength, usually in the range of 700-900 MPa and 500-650 MPa respectively.
The combination of high strength and ductility allows the design of lightweight yet strong structural elements.
The excellent mechanical properties of 1.4410 ensure the structural integrity of the hollow profiles, allowing them to withstand static and dynamic loads in water treatment applications.

1.4410 maintains its mechanical properties and corrosion resistance over a wide temperature range from high to cryogenic conditions.
This thermal stability is particularly beneficial for water treatment applications involving temperature fluctuations, such as desalination plants or cold climate water storage facilities.

1.4410 stainless steel is easy to weld, but welding parameters require careful control of the welding parameters to maintain the desired ferrite-austenite balance.
The high strength and ductility of 1.4410 make it suitable for a variety of manufacturing techniques, including rolling, bending and welding, allowing the production of hollow structural profiles with different cross-sectional shapes and sizes.

1.4410 stainless steel generally has a wider range of applications and may cost slightly less than the more specialized 2507 (UNS S32570) superduplex stainless steel.
This wider availability and potentially lower cost could make 1.4410 a more accessible and cost-effective option for certain water treatment projects.

The combination of corrosion resistance, mechanical properties and manufacturing flexibility makes 1.4410 stainless steel an excellent choice for hollow structural profiles in water treatment applications. While it may not offer the same level of corrosion resistance as 2507 superduplex stainless steel, 1.4410 still provides superior performance in a variety of water treatment environments, making it a viable and cost-effective alternative.
