Super Duplex Steel S32750 pipe fittings are composed primarily of iron, with chromium (25-26%), molybdenum (3-4%), nickel (6-8%), and a small amount of nitrogen (0.24-0.32%). This composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride environments. The mechanical properties of S32750 include a high tensile strength of 80-100 ksi (550-690 MPa), yield strength of 50-75 ksi (345-515 MPa), and elongation of 25%. This alloy offers superior toughness, high strength, and excellent resistance to both corrosion and fatigue.

Super Duplex Steel S32750 Pipe Fittings consist of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which results in a high Pitting Resistance Equivalent Number (PREN > 40). The duplex microstructure (austenitic-ferritic) offers excellent tensile strength (to 800 MPa), high yield strength (~550 MPa), and superior pitting, crevice corrosion, and stress corrosion cracking resistance. The structure and fatigue resistance of the alloy are sustained even in severe temperature and pressure conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
