What is SS 1.4410 cold-rolled strip?

SS 1.4410 cold-rolled strip is a high-performance super duplex stainless steel (UNS S32750/Alloy 2507) produced via a cold-rolling process. It features exceptional corrosion resistance, a tensile strength of up to 1000 MPa, and high-temperature resistance up to 300°C. Characterized by its 50/50 austenitic-ferritic duplex microstructure, this material is specifically engineered for use in harsh, chloride-rich environments and marine settings.

 

What is the standard for 1.4410 strip?

1.4410 (X2CrNiMoN25-7-4) stainless steel strip is a high-performance super duplex alloy typically standardized under EN 10088-2 for technical delivery conditions of corrosion-resisting steels. It is widely classified by its UNS designation S32750 or ASTM grade (often aligned with ASTM A240 for pressure vessels) and is commonly referred to as 2507 Super Duplex.

 

We supply high-performance 1.4410 stainless steel strip products-including cold-rolled coils, precision thin strips, slit narrow strips, and foils-with a thickness range of 0.1 mm to 3.0 mm. We offer various surface finishes, such as 2B, BA, and polished options, specifically designed for applications in seawater desalination, offshore engineering, and high-pressure chemical environments. Furthermore, we provide precision slitting capabilities supported by a comprehensive quality certification system (including EN 10204 3.1/3.2 certificates and ASTM G48 corrosion testing).
