Super Duplex 32750 foil (Alloy 2507, 1.4410), boasting 25% Cr, 4% Mo, and 0.3% N, dominates in pitting/crevice corrosion (CPT 85°C+) and SCC resistance vs Duplex 2205 perfect for high-chloride sour gas where 2205 risks embrittlement. Yield strength of 550 MPa allows 40% thinner gauges, optimizing weight/cost in umbilicals.
