Super Duplex 1.4410 Pipes — Frequently Asked Questions
Find answers to common questions about Super Duplex steel, UNS S32750 pipe price, and its specialized applications.
Super Duplex steel is characterized by its dual-phase microstructure (approx. 50% austenite, 50% ferrite) and its high alloying content (Chromium, Molybdenum, Nitrogen). This results in a pitting resistance equivalent number (PREN) typically above 40, offering both high strength and exceptional resistance to localized and stress corrosion cracking.
UNS S32750 is specified for environments with high chloride concentrations, high pressure, or high acidity. This includes seawater handling systems, pressure vessels, chemical tankers, and piping in highly aggressive petrochemical and upstream oil & gas (offshore) applications.
Welding Super Duplex requires careful control. The recommended filler metal is typically ER2594 or a matching alloy like ER2209 (for thinner sections). We ensure the use of suitable welding procedures to maintain the critical phase balance and avoid brittle intermetallic phases.
Both are Super Duplex grades. 1.4501 (S32760) contains a small, controlled amount of Copper (Cu) and Tungsten (W), giving it a slightly higher PREN and marginally better corrosion resistance in certain highly acidic or concentrated chloride environments. S32750 is the more common and widely used Super Duplex grade.
