Super Duplex 2205 | Product Overview
Introduction To Super Duplex Stainless Steel 2205
Super Duplex Stainless Steel 2205 is a dual-phase (ferritic-austenitic) stainless steel that combines exceptional corrosion resistance with high strength. It contains approximately 22% chromium, 5–6% nickel, and 3% molybdenum, giving it superior resistance to pitting, crevice corrosion, and stress corrosion cracking compared to conventional austenitic and ferritic stainless steels.
Moksh Tubes & Fittings LLP is a trusted supplier, exporter, importer, and stockist of Duplex Stainless Steel 2205 (UNS S32205 / S31803 / ASTM A182 F51). Our product portfolio includes Pipes, Tubes, Sheets, Plates, Coils, Bars, Pipe Fittings, Flanges, Fasteners, Welding Rods, Wire Mesh, and custom fabricated components.

FAQ – Duplex Stainless Steel 2205
Is 2205 Duplex or Super Duplex?
2205 is Duplex Stainless Steel — not Super Duplex. Super Duplex grades include 2507 / S32750 / S32760.
What makes 2205 corrosion resistant?
High Cr–Mo–N content gives strong resistance to pitting, crevice corrosion & chloride SCC.
What industries prefer 2205?
Oil & gas, chemical plants, desalination, marine engineering, pulp & paper, and structural applications.
Can 2205 be welded?
Yes — but heat input must be controlled for phase balance.
What services does Moksh Tubes provide?
High-quality materials, custom fabrication, global supply & full technical support.
