2507 Duplex Stainless Steel Plate
2507 Duplex Stainless Steel Plate is classified as a Super Duplex Stainless Steel due to its higher alloying content (25% Chromium, 7% Nickel, 4% Molybdenum, plus Nitrogen), offering enhanced strength and corrosion resistance beyond the standard 2205 grade. It provides exceptional strength and superior resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive, chloride-rich media. This grade is essential for the most severe service environments, primarily in offshore oil and gas equipment (subsea piping, risers), chemical and petrochemical processing (pressure vessels, heat exchangers), and desalination plants (high-pressure reverse osmosis equipment).
