Duplex stainless steel plates combine high strength with excellent corrosion resistance, particularly in chloride-containing environments. We supply 2205 (S31803/S32205), 2507 (S32750) Super Duplex, and LDX 2101 Lean Duplex grades. These grades offer approximately twice the yield strength of standard austenitic stainless steels while maintaining good weldability and resistance to stress corrosion cracking. Used in chemical plants, desalination equipment, oil and gas processing, and marine applications.
LDX 2101 (UNS S32101) is a lean duplex stainless steel plate offering double the yield strength of 304, high SCC resistance, and excellent price stability due to its low nickel content. Thickness 0.3-100mm. Supplied with EN 10204 3.1 MTC.
