Manufacturer, Supplier & Exporter of EN 1.4462 Spool
EN 1.4462 is the European designation for the widely used duplex stainless-steel grade commonly known in UNS as S32205. This alloy is known for its excellent strength and corrosion resistance, especially in chloride-rich environments. When fabricated in the form of a spool — a prefabricated assembly of pipes, fittings, elbows, tees, and flanges — it provides a ready-to-install module, reducing on-site welding, increasing installation speed, and improving quality consistency. Riddhi Siddhi Impex, a leading manufacturer and supplier in India, offers EN 1.4462 spool assemblies tailored to demanding industrial requirements..
EN 1.4462 / S32205 duplex stainless steel combines a balanced two-phase microstructure of ferrite and austenite. This structure gives the material almost double the yield strength compared to typical austenitic stainless steels, along with very good toughness. The high chromium (~22 %) and molybdenum (~3 %) content, along with nitrogen (≈0.14–0.20 %), contribute to its excellent resistance to localized corrosion (pitting and crevice), while maintaining high mechanical performance..
EN 1.4462, also known as Duplex 2205, is a high-performance duplex stainless steel that combines excellent mechanical strength with superior corrosion resistance. Manufactured in spool form, it comes as a prefabricated piping assembly comprising pipes, elbows, tees, and flanges, designed for easy installation in complex piping systems. Riddhi Siddhi Impex, a leading manufacturer and supplier in India, specializes in providing ready-to-use EN 1.4462 spool assemblies that meet industrial quality standards and are optimized for various process applications.
EN 1.4462 has a two-phase microstructure of austenite and ferrite, typically in a 50:50 ratio. This duplex structure enhances both tensile and yield strength while providing excellent resistance to stress corrosion cracking. The alloy’s chemical composition includes approximately 22% chromium, 5–6% nickel, 3% molybdenum, and 0.14–0.20% nitrogen, which collectively enhance pitting and crevice corrosion resistance in chloride-rich or acidic environments. This composition ensures durability and long-term performance in demanding industrial applications..
EN 1.4462 is highly resistant to localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking, which is especially important for offshore, chemical, and desalination applications. Its enhanced corrosion resistance makes it suitable for transporting aggressive media such as seawater, acids, or chloride-containing fluids. The presence of molybdenum and nitrogen significantly boosts its resistance to pitting and crevice corrosion, ensuring long-term reliability even under harsh conditions..
