Key Features of UNS S32750 Duplex Pipes & Tubes
Exceptional Corrosion Resistance – Resists chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion.
High Mechanical Strength – Superior to standard austenitic and ferritic steels.
Thermal Stability – Recommended for use up to 600°F (316°C); prolonged high-temperature exposure may reduce toughness.
Acid Resistance – Performs exceptionally against organic (formic, acetic) and inorganic acids, especially chloride-rich environments.
Low Thermal Expansion – Ensures dimensional stability under thermal stress.
Excellent Weldability & Formability – Facilitates fabrication and installation.
