Super Duplex 2507 vs X2CrNiMoCuWN25-7-4
Side-by-side chemical composition and mechanical property comparison.
Overview
Super Duplex 2507
1.4410
Super duplex stainless steel with PREN >40. Superior corrosion resistance to standard 2205 duplex, especially in chloride and H₂S environments. Used for subsea pipelines, offshore platform components, desalination plants, and chemical processing equipment.
X2CrNiMoCuWN25-7-4
1.4501
Super duplex stainless with W + Cu addition — trade name Zeron 100 (Rolled Alloys). PREN >41 — even higher than SAF 2507 (1.4410) due to tungsten contribution. Outstanding pitting, crevice, and stress corrosion cracking resistance in hot seawater and aggressive chlorides. Used for subsea oil/gas equipment, seawater desalination, FGD systems, and chemical tankers in the most aggressive chloride environments.
