Deep in the Gulf of Mexico, a subsea manifold faced catastrophic CSCC from H2S-laced brine, where standard duplexes cracked under pressure until Super Duplex 32760 foil (UNS S32760) liners intervened, with PREN 40+ and 550 MPa yield slashing failures by 4x and saving millions in downtime for oil & gas engineers.

Super Duplex 32760 foil (Zeron 100, Werkstoff 1.4501), with 24-26% Cr, 3-4% Mo, W/Cu additions, offers unmatched resistance to pitting (CPT >90°C), CSCC, and sulfide stress cracking vs standard duplex 2507 or 2205 ideal for sour gas where others embrittle. Its balanced microstructure triples strength over austenitics, enabling 40% weight reduction in high-pressure components.
